In most cases it can be repaired. Moving to an SSD and adding memory give a five to eight year old machine several more years of comfortable use, for far less than the cost of replacing it.
Covered in : Ordinateur lent
A software cleanup and a startup tidy take one to two hours. Replacing a drive with an SSD, including the transfer of all your data, generally takes half a day.
Covered in : Ordinateur lent
It deals with the software causes, but not with a mechanical drive, a shortage of memory or overheating. That is why a diagnosis before reinstalling often saves a pointless job.
Covered in : Ordinateur lent
Not necessarily. That freeze often comes from a USB device plugged in at startup, or from a lost boot setting. Unplug everything connected, USB sticks and external drives included, then try again.
Covered in : PC qui ne démarre plus
In most cases, yes. If the drive is not physically damaged, the data is intact and is recovered by connecting it to another machine. A startup fault is not data loss.
Covered in : PC qui ne démarre plus
That depends entirely on the cause : a software repair is nothing like replacing a motherboard. Since the diagnosis is free, you know the figure before committing to anything.
Covered in : PC qui ne démarre plus
It clearly speeds up loading and program startup, but not the calculations themselves, which depend on the processor and graphics card. For office work and everyday use, the difference is dramatic.
Covered in : SSD ou disque dur
Yes, and on a desktop it is often a good idea : the SSD takes the system, the old drive becomes storage. On a laptop it needs a free bay, which is not always there.
Covered in : SSD ou disque dur
Taking the machine apart is quick ; it is copying the data that takes time, generally a few hours depending on the volume. The machine comes back ready to use, with nothing to set up again.
Covered in : SSD ou disque dur
Not necessarily. If the case and the screen are in good condition and the memory can be extended, an SSD and a general service often give it several more years for a modest outlay.
Covered in : Quand changer d'ordinateur
Documents, photos, email and bookmarks transfer across in full. Software has to be reinstalled, but the licences can usually be reused.
Covered in : Quand changer d'ordinateur
A professionally refurbished machine is tested, cleaned, fitted with new parts where needed and sold with a warranty. It is generally business hardware, sturdier than the consumer entry level.
Covered in : Quand changer d'ordinateur
Not necessarily. Microsoft Defender, built in and up to date, scores comparably to commercial products for home use. What matters is having only one active, and letting it update itself.
Covered in : Supprimer un virus
A classic virus, rarely. Ransomware, yes : it encrypts files and makes them unusable. That is why a backup kept disconnected from the machine remains the only truly reliable protection.
Covered in : Supprimer un virus
Never. No software company puts a phone number in an alert. That is the very mechanism of the fake tech support scam.
Covered in : Supprimer un virus
No. The great majority of fraudulent links lead to a fake login page meant to steal a password, not to install a program. If you typed nothing and downloaded nothing, the risk stays low.
Covered in : J'ai cliqué sur un lien frauduleux
It is advisable as soon as there is a financial loss, and banks often require it for the dispute. Reporting is useful even where no money was lost.
Covered in : J'ai cliqué sur un lien frauduleux
Change the password from another device, turn on two-factor authentication, then check the forwarding rules and the authorised apps in the account settings. That is where access is most often maintained.
Covered in : J'ai cliqué sur un lien frauduleux
No. It is an ordinary web page that has scanned nothing and has access to nothing. The message is entirely fabricated to provoke a phone call.
Covered in : Fausse alerte de virus
Never. Microsoft does not call private individuals and has no way of knowing that your machine has a problem. Any such call is a scam.
Covered in : Fausse alerte de virus
It is the only real guarantee if the person had full access. A cleanup may be enough in mild cases, but examining the machine is what settles it.
Covered in : Fausse alerte de virus
From directories, data leaks or resold lists. It does not mean your computer is infected, nor that anyone is watching you.
Covered in : Faux appel Microsoft
No. That kind of detail circulates in resold lists, and its whole purpose is to lend the call credibility.
Covered in : Faux appel Microsoft
A few minutes are enough to copy files or install permanent access. Have the machine checked and change your passwords from another device, as a precaution.
Covered in : Faux appel Microsoft
Usually from data leaks at retailers or online services, or from automated sending across ranges of numbers. It does not mean your phone is compromised.
Covered in : Faux SMS colis ou amende
For legitimate marketing, yes. For a fraudulent message, no : it only confirms the number is live. Report it to 33700 and delete it.
Covered in : Faux SMS colis ou amende
That is extremely rare and belongs to high-end targeted attacks. In these mass campaigns, simply reading the message carries no risk.
Covered in : Faux SMS colis ou amende
Usually through a fake login page, or through reusing a password that leaked from another service. Rarely through a direct attack on the platform.
Covered in : Compte piraté
From a few minutes with a verification code, to several days or weeks if identity checks are needed. Acting quickly counts for a great deal.
Covered in : Compte piraté
It is worth doing where there is financial loss, identity theft, or harmful messages sent in your name. Keep screenshots as evidence.
Covered in : Compte piraté
No. It can remove the program responsible, but the encryption stays. Only a key, a known decryption tool for that family, or a backup will bring the data back.
Covered in : Fichiers chiffrés, rançon
Not necessarily. Syncing may have spread the encrypted files, but version history often lets you go back to a clean copy. That is the first avenue to explore.
Covered in : Fichiers chiffrés, rançon
Identification and the recovery attempt generally take one to several days. The clean reinstall comes on top of that. Much depends on whether a backup exists.
Covered in : Fichiers chiffrés, rançon
It is less destructive than a virus, but it watches your browsing, sells it on, and often serves as a way in for more harmful programs. There is no reason to leave it there.
Covered in : Publicités intempestives
Only if the problem is confined to the browser. If a program is installed on the machine, it will reconfigure the browser the next time you open it.
Covered in : Publicités intempestives
It hides the symptoms without removing the cause, and has no effect on windows appearing outside the browser. It is still useful as prevention, once the cleanup is done.
Covered in : Publicités intempestives
For home use, no. An up-to-date Microsoft Defender offers comparable protection. Two-factor authentication and regular backups bring far more real security than another subscription.
Covered in : Sécuriser son ordinateur
The classic signs : unknown sign-ins reported by the service, messages sent without your knowledge, automatic forwarding rules created in your mailbox, or a sudden inability to log in. If in doubt, change the password from another device.
Covered in : Sécuriser son ordinateur
It is a cheap precaution with no downside. Blackmail messages claiming to hold images of you, on the other hand, are almost always bluff : they are sent en masse, with no images behind them at all.
Covered in : Sécuriser son ordinateur
That message means the connection to the local network is established and encrypted, but no route out to the internet is detected. The cause is generally the router or a network setting, not the Wi-Fi adapter.
Covered in : Wi-Fi sans Internet
No, and it is the typical symptom of a DNS problem or of filtering by an antivirus. Changing the DNS settles most of these cases.
Covered in : Wi-Fi sans Internet
A simple restart, yes. A factory reset, no : it wipes your configuration, network name and key included, and makes things needlessly complicated.
Covered in : Wi-Fi sans Internet
Close to the router, on the 5 GHz band and with a recent device, several hundred megabits is normal. Through two walls, dropping to a few dozen is just as normal.
Covered in : Internet lent
If your router is more than five years old, yes : recent models handle multiple devices and current Wi-Fi standards better. Providers often offer an exchange.
Covered in : Internet lent
Rarely. If the speed over cable is already good, upgrading the subscription changes nothing : it is the wireless side that needs work.
Covered in : Internet lent
It is not needed day to day, but a restart clears a good number of temporary blockages and forces the router to pick a less crowded channel. It is the first thing to try.
Covered in : Wi-Fi qui se déconnecte
Well placed, yes. Badly placed, it makes things worse by rebroadcasting an already weak signal and halving the speed. Its position matters more than its price.
Covered in : Wi-Fi qui se déconnecte
Absolutely, and it is common. Fibre stops at the router ; what happens after that depends entirely on the quality of the Wi-Fi. A cable test settles it in a minute.
Covered in : Wi-Fi qui se déconnecte
Powerline is almost always better as soon as a floor or a load-bearing wall has to be crossed, because it does not depend on the signal travelling. A repeater only suits short distances with no major obstacle.
Covered in : Zones sans Wi-Fi
No. It requires both sockets to be on the same meter, and its performance depends on the quality of the electrical installation. Testing first avoids an unpleasant surprise.
Covered in : Zones sans Wi-Fi
No, it is added to it. The router remains the point of entry ; its own Wi-Fi is usually turned off so the two networks do not compete.
Covered in : Zones sans Wi-Fi
Reckon on three to ten minutes on fibre, longer after a lengthy outage : the router sometimes picks up an update along the way. Do not unplug it during that phase.
Covered in : Voyant rouge sur la box
Yes. Each home has its own connection at the shared distribution point. A fault can be strictly individual, even within the same building.
Covered in : Voyant rouge sur la box
If it is more than five years old, exchanging it with your provider often brings better Wi-Fi and better handling of multiple devices. It is generally free.
Covered in : Voyant rouge sur la box
No, and that is exactly what the encryption is for. These methods only work on a network you already have access to, or whose router you have.
Covered in : Mot de passe Wi-Fi perdu
Not necessary if it is long and has never been widely shared. A guest network is a better answer than frequent changes.
Covered in : Mot de passe Wi-Fi perdu
Today's factory keys are long and random, so they are solid. On a very old router, on the other hand, changing it is advisable.
Covered in : Mot de passe Wi-Fi perdu
No, not with a network printer : it stands on its own on the Wi-Fi. That only applies to a USB printer shared from a machine.
Covered in : Ajouter une imprimante Wi-Fi
Most often because it only handles the 2.4 GHz band while your router broadcasts a 5 GHz network under a different name. Check the band before looking any further.
Covered in : Ajouter une imprimante Wi-Fi
Yes, as soon as the printer is on the same network. Printing is built into Android and iOS on most recent models, with no extra app.
Covered in : Ajouter une imprimante Wi-Fi
It is possible if the drive has been little used since, and unlikely if it has been used daily. Time matters less than how much writing has taken place since the deletion.
Covered in : Récupérer des fichiers
No, and nobody can seriously guarantee it before examining the media. The diagnosis can say what is recoverable and in what proportion, before you commit to anything.
Covered in : Récupérer des fichiers
Not necessarily. A quick format only removes the drive's table of contents, not the data. A full format, on the other hand, rewrites everything and makes recovery very unlikely.
Covered in : Récupérer des fichiers
No, never if the drive holds data you want to keep. That offer appears when the file table is damaged, while the data itself is still there.
Covered in : Disque externe non reconnu
A regular clicking means a mechanical failure in progress. Unplug it and do not plug it back in : every attempt reduces the chances of recovery.
Covered in : Disque externe non reconnu
Sometimes, but the work is then a hardware matter, not a software one. Do not plug it back in to test it, that often makes the damage worse.
Covered in : Disque externe non reconnu
A quick format only clears the index, and recovery remains possible. A full format rewrites the whole medium and makes recovery very unlikely.
Covered in : Clé USB illisible
That often comes from a drive-letter conflict or a faulty USB driver on the machine concerned. The stick itself is generally healthy.
Covered in : Clé USB illisible
A few years in regular use, less if it is heavily worked. Nothing warns you of the end, unlike a mechanical drive.
Covered in : Clé USB illisible
It makes a good third copy, but depends on an account and a connection. A physical medium in your own hands is still useful, particularly for large volumes of photos and video.
Covered in : Bien sauvegarder
It depends what you are willing to lose. A monthly backup means losing at most a month of work : it is for each person to judge whether that is acceptable.
Covered in : Bien sauvegarder
Five to eight years for a lightly used mechanical drive. A backup medium is not eternal and has to be replaced, which almost everyone forgets.
Covered in : Bien sauvegarder
Two causes dominate : a charging cable with no data wires, or the connection mode left on "Charging only". Unlock the phone and select file transfer.
Covered in : Photos du téléphone
No. It is syncing : a deletion on the phone propagates, and losing the account means losing access. An independent local copy is still needed.
Covered in : Photos du téléphone
Often yes, especially if they were synced with an account, or if only the screen is damaged. Much depends on the state of the device.
Covered in : Photos du téléphone
The contents of an old drive can be cloned, but that is rarely wise onto different hardware : you inherit the accumulated slowness and problems along with it. Starting clean is better.
Covered in : Changer d'ordinateur
A few hours, depending on the volume of data and the number of programs to reinstall. Copying the files is the longest part, the configuration the most delicate.
Covered in : Changer d'ordinateur
Keep it for a few months as a precaution, then have it securely erased before giving it away, selling it or recycling it. Formatting alone does not protect your data.
Covered in : Changer d'ordinateur
No. The stop exists precisely to avoid corrupted data being written. That said, if the blue screen comes from a failing drive, that drive threatens your files quite apart from the crash itself.
Covered in : Écran bleu
No. An isolated incident after an update or a power cut is ordinary. It is repetition, especially in the same circumstances, that points to a cause worth finding.
Covered in : Écran bleu
Only if they come from software. With faulty memory or a failing drive, the crashes will return identically on a freshly installed system.
Covered in : Écran bleu
No, that is more likely the browser or the connection. Try another browser and see whether the machine stays responsive during the freeze : if it does, the system is fine.
Covered in : Ordinateur qui se fige
Wait a minute or two first, many freezes clear on their own. If nothing moves, a long press on the power button is the only option left - and carries no particular risk once in a while.
Covered in : Ordinateur qui se fige
Only if they come from memory being full, which Task Manager will show. With a failing drive or overheating, adding memory changes nothing.
Covered in : Ordinateur qui se fige
In the vast majority of cases, no. The problem concerns starting the system, not the files, which remain readable from another machine.
Covered in : Redémarrage en boucle
Three forced shutdowns during the startup phase are enough : the menu appears on the fourth power-on. It is a mechanism Windows provides, and it is not dangerous.
Covered in : Redémarrage en boucle
Use the uninstall updates option in the advanced options. That is the scenario where it works best, and it does not touch your documents.
Covered in : Redémarrage en boucle
That is the typical picture of overheating or an underpowered supply. It is not beyond repair, but letting it continue damages components over time.
Covered in : PC qui s'éteint seul
Often yes on a machine under five years old. Beyond that, the thermal paste has generally dried out and needs replacing for the cleaning to have its full effect.
Covered in : PC qui s'éteint seul
It helps, especially in summer and on a thin model. It is only a palliative though : if the internal vents are clogged, no external fan will make up for it.
Covered in : PC qui s'éteint seul
Avoid it absolutely while the drive is working. A shutdown while system files are being written can leave Windows unable to start. Only force a shutdown after a long, complete standstill.
Covered in : Mise à jour bloquée
That is the sign of a specific, repeatable cause : not enough disk space, a corrupted file or an incompatible driver. The error code shown tells you which.
Covered in : Mise à jour bloquée
In normal operation, no. Temporary user profiles do occur after a major update : the documents are then present but in another folder, and recoverable.
Covered in : Mise à jour bloquée
No, it keeps working normally. It is the security fixes that stop, which leaves the machine progressively more exposed to known flaws.
Covered in : Passer à Windows 11
No, it is free for eligible machines with a valid Windows 10 licence.
Covered in : Passer à Windows 11
Yes, for a limited period after the migration - ten days as a rule. After that, going back requires a full reinstall.
Covered in : Passer à Windows 11
No, the documents stay intact. One caution though : on a local account, a reset forced by certain tools can lose access to encrypted files and to passwords saved in the browser.
Covered in : Mot de passe oublié
Microsoft offers a longer account recovery form, which asks you to prove your identity through a series of details about the account. It generally takes a few days.
Covered in : Mot de passe oublié
No, and rightly so. A serious technician will ask for proof of ownership, and a drive protected by BitLocker stays inaccessible without its recovery key.
Covered in : Mot de passe oublié
Unlocking with a code is immediate. The identity recovery form generally takes a few days, and may need several attempts if the details given are too vague.
Covered in : Compte Microsoft bloqué
Yes, a local account is still possible. You lose syncing and the online backup of the BitLocker key, but the machine works normally.
Covered in : Compte Microsoft bloqué
Those that exist only in the cloud, yes. Those downloaded locally stay on the machine. It is a good argument for not depending on the cloud alone.
Covered in : Compte Microsoft bloqué
No, it is a safe operation. It only restarts the graphical interface. Simply save any open documents first, as a precaution.
Covered in : Menu Démarrer bloqué
It indicates damaged system files or a corrupted user profile. It is not serious for your data, but it calls for a thorough repair.
Covered in : Menu Démarrer bloqué
Rarely. Repairing the system files or creating a new profile settles almost every case without a reinstall.
Covered in : Menu Démarrer bloqué
Being an administrator entitles you to take ownership of a folder, but does not automatically give access to files belonging to another account. Ownership has to be taken explicitly.
Covered in : Accès refusé aux fichiers
No, it only changes access rights, not the contents. The only real risk is applying it too widely, to system folders.
Covered in : Accès refusé aux fichiers
No. That is the sign of ransomware encryption, and no amount of rights work will change it. Switch the machine off and have it examined.
Covered in : Accès refusé aux fichiers
Every two to three years in domestic use. Far more often with pets, tobacco, or in a dusty workplace : hair and particles clog heatsinks very quickly.
Covered in : Surchauffe et bruit
It gains a few degrees, especially in summer. It is only a supplement though : if the internal fins are blocked, no external fan will make up for it.
Covered in : Surchauffe et bruit
That happens when a program is working the processor in the background, or after a changed power setting. Look at what is running before concluding there is a hardware problem.
Covered in : Surchauffe et bruit
Three to five years in ordinary use, or roughly 500 to 1000 charge cycles. Heat shortens that noticeably.
Covered in : Batterie qui ne tient plus
No, that is a habit inherited from an older technology. Lithium batteries prefer frequent partial charges to full discharges.
Covered in : Batterie qui ne tient plus
No. A swollen battery is a fire risk and distorts the case. Stop using it and have it replaced without delay.
Covered in : Batterie qui ne tient plus
Yes, provided the voltage is identical and the power at least equivalent. A different voltage can damage the machine, and insufficient power will never recharge the battery.
Covered in : Portable qui ne charge plus
It means the battery no longer holds any charge at all. The machine is still usable as a desktop, but a new battery is needed to get its portability back.
Covered in : Portable qui ne charge plus
On a machine that is otherwise in good condition, yes : it is a routine repair and far cheaper than replacing the computer.
Covered in : Portable qui ne charge plus
Not at all. The drive is not involved, and your files stay accessible - including by simply plugging in an external monitor.
Covered in : Écran cassé
No. A panel is a sealed assembly of layers ; a crack cannot be filled and the ink blotch will keep spreading. Replacement is the only answer.
Covered in : Écran cassé
That depends entirely on the model. Common panels are available quickly ; unusual resolutions or recent models can take longer.
Covered in : Écran cassé
That is the characteristic sign of a damaged or badly connected video ribbon, often at the hinge. The panel itself is generally intact.
Covered in : Lignes sur l'écran
No, it is nearly always the graphics driver or the refresh rate. Reinstalling the official driver is enough in the great majority of cases.
Covered in : Lignes sur l'écran
On a desktop it is easily replaced. On a laptop where it is soldered to the motherboard, the job is heavy and rarely worthwhile on an older machine.
Covered in : Lignes sur l'écran
No, the layout has switched to QWERTY. The Left Alt + Shift shortcut restores AZERTY immediately.
Covered in : Clavier en panne
Sometimes, if the mechanism under the keycap is intact. If the clip is broken, the whole keyboard has to be replaced on most laptops.
Covered in : Clavier en panne
Yes, with no technical problem at all. It is a perfectly viable answer on a machine used mainly in one place.
Covered in : Clavier en panne
It depends on the manufacturer, but it is always a key in the F1 to F12 row bearing a crossed-out rectangle, alone or combined with Fn.
Covered in : Pavé tactile inactif
Scrolling or gestures that no longer respond generally come from the driver, not the hardware. Reinstalling the manufacturer's driver is usually enough.
Covered in : Pavé tactile inactif
Yes, it almost always indicates a battery swelling underneath. Stop using it for long periods and have the machine examined without delay.
Covered in : Pavé tactile inactif
The volume mixer keeps a separate level for each application. One of them is probably muted or directed to another output.
Covered in : Plus de son
Yes, it is a classic : the update replaces the manufacturer's driver with a generic one. Reinstalling the official driver generally settles it.
Covered in : Plus de son
Yes, speakers can be replaced. Check the balance in the audio settings first : it sometimes shifts, and correcting it costs nothing.
Covered in : Plus de son
The port supplies power but the stick is not recognised by the system. That often comes from an unassigned drive letter or a damaged file table - it is not necessarily data loss.
Covered in : Ports USB en panne
Often it is the USB selective suspend setting cutting them to save power. Disabling it in the power options settles many of these cases.
Covered in : Ports USB en panne
On a desktop, yes, with an inexpensive expansion card. On a laptop, an external hub is the only option, preferably with its own power supply.
Covered in : Ports USB en panne
Almost always because its network address changes every time the router restarts. Reserving a fixed address for the printer in the router settles it for good.
Covered in : Imprimante en panne
They do not damage it, but some models refuse them after an update to their internal software. An error message on a brand-new cartridge often comes from that.
Covered in : Imprimante en panne
On entry-level models, the cost of a part frequently exceeds that of a new device. A laser printer or a professional model, on the other hand, is well worth repairing.
Covered in : Imprimante en panne
Yes. Corrosion acts over days or weeks : a machine that works on the first day can fail well afterwards. A preventive clean is strongly advisable.
Covered in : Liquide renversé
No. It absorbs moisture from the air, not moisture trapped in the circuits, and it leaves residues. It is a persistent belief with no real effect.
Covered in : Liquide renversé
It depends on the liquid, the quantity, and above all how quickly you react. Clean water with a machine never switched back on offers good prospects ; a fizzy drink with several attempts to power up, far less.
Covered in : Liquide renversé
Yes. We identify the cause and give you a quote before any repair. You are free to say no: nothing is charged if you do not go ahead.
Covered in : Dépannage à domicile
Yes, and it is better that way. You know the machine's history, your passwords stay in your hands, and you see what is being done to your data.
Covered in : Dépannage à domicile
Our hours cover a wide range, six days a week. For an urgent situation, say so at the first contact: see our emergency IT support page.
Covered in : Dépannage à domicile
No. We only reach files when the work requires it - a backup or a transfer - and never their contents. Your documents remain yours.
Covered in : Dépannage à domicile
It depends on the real urgency and on the nature of the fault. Many situations are handled remotely straight away; for an on-site visit, we give you a slot on the first call.
Covered in : Dépannage entreprise
We handle the environment it runs in: the machine, the network, the database, access rights, backups. For configuring the software itself, the vendor remains the right contact, and we are happy to work alongside them.
Covered in : Dépannage entreprise
No. One-off work is possible with no commitment. Ongoing follow-up is mainly worthwhile from a few machines upward, or when the business cannot afford to stop.
Covered in : Dépannage entreprise
Isolate the machines from the network immediately, unplug any backups still connected and switch nothing else off before reaching us. Some of what is on the disks helps identify the family and sometimes recover the files.
Covered in : Dépannage entreprise
Our hours cover a wide range, six days a week. Flag the urgency at the first contact and say what is blocked: that lets us give you a realistic slot.
Covered in : Dépannage urgent
The diagnosis is still free and the quote still comes before any repair, emergency or not. So you know what you are committing to before anything starts.
Covered in : Dépannage urgent
In the vast majority of cases, no. A startup failure concerns the system, not the files, which stay readable when the disk is connected to another machine.
Covered in : Dépannage urgent
We work on Windows laptops, all makes. For Macs and MacBooks, our specialist site apple-lyon.com takes over with the right skills and the right parts.
Covered in : Réparation portable
Often yes, but the job is heavier than it looks: the hinge frequently tears its mounting points out of the case. The diagnosis will say whether the repair will last.
Covered in : Réparation portable
It depends entirely on the panel: resolution, technology, whether it is a touchscreen, how it is mounted. That is why we draw up a quote after identifying the exact model, never over the phone.
Covered in : Réparation portable
Yes, in the vast majority of cases. The disk is connected to another machine and your files transfer in full, even if the computer itself is beyond repair.
Covered in : Réparation portable
On a desktop, repair is often the right call: the parts are standard and inexpensive. The turning point is Windows 11 compatibility rather than mechanical condition.
Covered in : Réparation ordinateur fixe
On a desktop computer, yes, and at a reasonable cost. Compatibility with the existing processor and memory has to be checked, which the diagnosis establishes.
Covered in : Réparation ordinateur fixe
It depends on the source. A fan blowing hard signals a build-up of dust, which a clean-out reverses. A clicking coming from the disk is a good deal more serious and means switching the machine off.
Covered in : Réparation ordinateur fixe
Absolutely not. The disk is not involved and your files remain intact. They are in fact reachable straight away by simply plugging in an external monitor.
Covered in : Réparation d'écran
No. A panel is a sealed stack of layers: a crack cannot be filled and the ink blotch will keep spreading. Replacement is the only answer.
Covered in : Réparation d'écran
Common resolutions are available quickly. Unusual panels or very recent models take longer, and we tell you how long with the quote.
Covered in : Réparation d'écran
Yes, because the touch glass is a separate part from the panel and the two are sometimes bonded together. The diagnosis determines whether only one needs changing.
Covered in : Réparation d'écran
No, the layout has simply switched to QWERTY. A keyboard shortcut restores AZERTY immediately, and the unwanted layout can be removed for good.
Covered in : Remplacement de clavier
Sometimes, if the mechanism under the keycap is intact. If the clip is broken or the conductive film is worn, the whole keyboard has to be replaced.
Covered in : Remplacement de clavier
From thirty minutes on models where it unclips from above, to several hours on those that require the palm rest to be fully stripped down.
Covered in : Remplacement de clavier
It is the most frequent cause, but not the only one: the motherboard, the memory or the power button can produce the same symptom. Diagnosis by elimination settles it in a few minutes.
Covered in : Alimentation et charge
Yes if the voltage is identical and the wattage at least equivalent. A different voltage can damage the machine, and insufficient wattage will never charge the battery.
Covered in : Alimentation et charge
Yes, it is a routine workshop repair: the socket is resoldered or replaced. On a machine that is otherwise in good condition, it is well worth it.
Covered in : Alimentation et charge
It can on cheap models with no protection. That is one of the reasons we do not fit bargain power supplies in the machines we repair.
Covered in : Alimentation et charge
Not necessarily. Microsoft Defender, built in and up to date, scores comparably to commercial products for home use. What matters is having only one active.
Covered in : Suppression de virus
Allow one to two hours for a normal case, longer if the symptoms came back after an earlier clean-up. The manual part is the longest, and it is the one that prevents a relapse.
Covered in : Suppression de virus
A clean-up does not touch your documents. The only case where files are genuinely at stake is ransomware, which encrypts them - and there, only a backup or a known decryption tool will get them back.
Covered in : Suppression de virus
The signs of a return are always the same: ads outside the browser, a home page that changes on its own, an antivirus that turns itself off. A relapse a few days after a clean-up almost always comes from a scheduled task that was missed.
Covered in : Suppression de virus
For home use, yes, provided it is active, up to date and alone. Independent tests put it on a level with commercial products, at no cost and with no slowdown.
Covered in : Installation d'antivirus
No. Two active antivirus products get in each other's way, slow the machine down and protect less well than one. Cleanly uninstalling the previous one is part of the installation.
Covered in : Installation d'antivirus
Partly. It blocks known variants, but not all of them. The only genuinely reliable protection remains a backup disconnected from the machine.
Covered in : Installation d'antivirus
Yes, minimal protection is still worth having: USB sticks and external disks carry infections too. An occasional scan is enough in that situation.
Covered in : Installation d'antivirus
No. It blocks known variants, but new ones get through. The only genuinely reliable protection is a backup the program cannot reach.
Covered in : Protection rançongiciel
The authorities unanimously advise against it, and for practical reasons: nothing guarantees the key, paying funds the activity and marks you out as a target good for the money next time.
Covered in : Protection rançongiciel
Not necessarily. Syncing may have propagated the encrypted versions, but version history often allows a return to a clean version. It is the first avenue to explore.
Covered in : Protection rançongiciel
Yes, and increasingly so: the attacks are automated and do not choose their targets. A badly protected small business is easier to reach than a large group.
Covered in : Protection rançongiciel
With two-factor authentication on email and a tested offline backup. Those two cover most of the real risk, and the first is free.
Covered in : Sécurisation PME
For a small or medium business, rarely. Most of it is handled as part of routine maintenance, provided someone regularly checks that the measures are still in place.
Covered in : Sécurisation PME
The question no longer works that way: the attacks are automated and do not choose their targets. A badly protected organization is hit because it is reachable, not because it was singled out.
Covered in : Sécurisation PME
Isolate the machine from the network, change the passwords from another device starting with email, and check the account's automatic forwarding rules. Then have the machine examined.
Covered in : Sécurisation PME
Yes, and it is often more revealing: in small organizations nobody has IT in their remit, and the weak points build up without anyone seeing them.
Covered in : Audit de sécurité
No. Most of it is done by observation and by looking at configurations. Only the restore test needs a little availability, and it can be scheduled.
Covered in : Audit de sécurité
That is precisely the aim. Each point states the concrete risk and what the fix costs. A report you cannot use serves no purpose.
Covered in : Audit de sécurité
Yes, but nothing obliges you to. The document is written to be usable by any provider, including the one already working with you.
Covered in : Audit de sécurité
Far less than on a hard drive: the TRIM function genuinely erases the freed blocks, often within a few minutes. Switching the machine off straight away is the only thing that improves your chances.
Covered in : Récupération sur SSD
No, and nobody can seriously guarantee it before examining the media. The diagnosis does say what is recoverable and in what proportion, before you commit to anything.
Covered in : Récupération sur SSD
Often yes, more so than a mechanical drive: with no moving parts, a knock rarely damages the memory chips. It is the circuit board or the controller that suffer.
Covered in : Récupération sur SSD
On a medium whose data genuinely matters, it is risky : installing the software and writing the recovered files can overwrite exactly what you are looking for. If the loss is important, do not attempt anything.
Covered in : Récupération sur SSD
Not fully by default. Some folders may be synced with online storage without you choosing it, which is not the same thing as a backup with history.
Covered in : Sauvegarde automatique
While it runs, slightly. That is why it is scheduled for a quiet hour. Later backups only handle changed files and are therefore quick.
Covered in : Sauvegarde automatique
Rarely worthwhile for a household: a clean reinstall beats restoring an already cluttered system. It is your data that counts.
Covered in : Sauvegarde automatique
By actually opening a few restored files, twice a year. It is the only check with any value: a green icon proves nothing.
Covered in : Sauvegarde automatique
It depends on what you are willing to lose. A daily backup means losing at most one day's work: it is for each business to judge whether that is acceptable.
Covered in : Sauvegarde d'entreprise
It makes a good off-site copy, but depends on an account and a connection. A local copy speeds up everyday restores considerably, and those account for most of the real need.
Covered in : Sauvegarde d'entreprise
Several generations at least, so you can go back before corruption that went unnoticed. The duration then depends on your own obligations, accounting ones in particular.
Covered in : Sauvegarde d'entreprise
It is a real and frequent risk. We always document the arrangement: where the media is, which passwords, what the restore procedure is. Without that, the backup dies with its keeper.
Covered in : Sauvegarde d'entreprise
They are syncing services: a deletion propagates, and losing the account means losing access. With version history switched on and understood they come close, but a local copy remains useful.
Covered in : Sauvegarde cloud
The large services offer infrastructure far more robust than a disk sitting on a desk. The real question is access to your account: that is where most incidents happen.
Covered in : Sauvegarde cloud
From a few hours to several days depending on the volume and your upload speed, often far lower than your download speed. You start with the essential data, the rest follows.
Covered in : Sauvegarde cloud
The data is deleted after a period that varies by provider. So it has to be brought back before cancelling, which takes time: plan ahead.
Covered in : Sauvegarde cloud
No. Redundancy protects against a disk failure, not against deletion, ransomware, theft or fire. The NAS must itself be backed up elsewhere.
Covered in : Installation NAS
Yes, that is how it is meant to work: it uses little power and manages its own sleep phases. Repeated shutdowns do more harm than continuous use.
Covered in : Installation NAS
Yes, but it is the most sensitive point: a badly exposed NAS is attacked automatically. That access is configured with specific precautions, never by simply opening a port.
Covered in : Installation NAS
With redundancy, the NAS carries on working and you replace the failed disk. But you have to be told: with no alert configured, nobody notices.
Covered in : Installation NAS
In practice from three or four machines, or as soon as work stops when the IT goes down. Below that, occasional work remains cheaper and we will say so.
Covered in : Maintenance PME
No. We also work on demand, with no commitment. A contract brings regular follow-up and knowledge of your setup, not an obligation to go through us.
Covered in : Maintenance PME
We handle the environment it runs in: the machine, the network, the database, rights, backups. Configuring how it works stays with the vendor, whom we are happy to deal with.
Covered in : Maintenance PME
A frequent and often awkward case. The documentation we keep - access, administrator passwords, procedures - is precisely what makes continuity possible without starting over.
Covered in : Maintenance PME
We work on short terms, with a reasonable notice period. A long contract only protects the provider: if the service suits you, it renews naturally.
Covered in : Contrat de maintenance
No, hardware is quoted separately. The contract covers follow-up, monitoring and advice, including anticipating the replacements to come.
Covered in : Contrat de maintenance
You get the full documentation of the setup, the access and the administrator passwords. They have been yours from the start, the contract only keeps them up to date.
Covered in : Contrat de maintenance
That is in fact the most common route. A few one-off jobs let you see whether we get on, before formalizing anything.
Covered in : Contrat de maintenance
Maintenance covers the technical upkeep of the setup. Managed IT adds the running of it: user accounts, dealing with other providers, tracking contracts and advice on what to change.
Covered in : Infogérance
No, unless you choose off-site backup, and then you know exactly what happens. Managed IT is about running things, not about hosting your files.
Covered in : Infogérance
No, and we prefer to say so plainly. We cover a wide range of hours six days a week. A business needing permanent on-call cover should go to an organization built for it.
Covered in : Infogérance
Absolutely, and it is a common arrangement: the in-house person handles the day-to-day and the business side, we handle the infrastructure, security and anything needing a step back.
Covered in : Infogérance
It depends on the arrangement. Under regular follow-up, everyday support is included. On demand, it is charged per job, with the figure given beforehand.
Covered in : Assistance utilisateurs
Yes, and it is the most efficient way: it saves the owner acting as a relay. We agree together on who can call and about what.
Covered in : Assistance utilisateurs
We check the machine and the account's access straight away. A quick report beats an infection discovered three weeks later.
Covered in : Assistance utilisateurs
For email, accounts and access to company files, yes. For repairing the phones themselves, no.
Covered in : Assistance utilisateurs
Not necessarily. On a small setup, taking a record during visits is enough. A monitoring tool becomes worthwhile from around ten machines, or where there is a server.
Covered in : Gestion de parc
Allow half a day for an organization of five to fifteen machines, plus writing the document up. It is a one-off task, after which it is updated as we visit.
Covered in : Gestion de parc
Yes, entirely, and it is written to be usable by anyone, including another provider. That is precisely what gives it its value.
Covered in : Gestion de parc
We track them and warn you before they expire. The contracts stay in your name: that is a rule we do not bend.
Covered in : Gestion de parc
Not always. Existing conduits, skirting boards and powerline adapters often avoid building work. We look at what can be done before proposing anything.
Covered in : Installation réseau
For simple home use, yes. As soon as there are several work machines, a server or a lot of connected devices, it becomes limiting and is better confined to internet access.
Covered in : Installation réseau
From half a day for a home to several days for business premises with cabling. The quote states the duration after a site visit.
Covered in : Installation réseau
Yes, and it is common. We start with a review: it is rare that everything has to be redone, a few targeted corrections are often enough.
Covered in : Installation réseau
Well placed, yes. Badly placed, it makes things worse by rebroadcasting an already weak signal and halving the speed. Where it sits matters far more than what it cost.
Covered in : Configuration Wi-Fi
No. They need both sockets to be on the same meter, and their performance depends on the electrical installation. A test beforehand tells you in ten minutes whether it will work.
Covered in : Configuration Wi-Fi
If it is more than five years old, swapping it with your operator often brings a real gain, and it is generally free. That does not replace good placement.
Covered in : Configuration Wi-Fi
Yes, with an access point built for outdoor use or a cable run to the building. It is a frequent request, and it can be done properly.
Covered in : Configuration Wi-Fi
Rarely. Testing the existing links shows which are usable. You then add what is missing rather than starting over.
Covered in : Câblage et baie
Category 6 amply covers current and future business and home needs. Higher categories are only justified on particular links.
Covered in : Câblage et baie
Often yes, by reusing existing conduits or running trunking along the skirting boards. We look at that during the site visit.
Covered in : Câblage et baie
Two at least: one for the computer, one spare for a phone, a printer or a second screen. The extra cost during the work is marginal.
Covered in : Câblage et baie
The question no longer works that way: the attacks are automated and sweep the internet without choosing. An organization is hit because it is reachable, not because it was singled out.
Covered in : Sécurisation du réseau
It depends on the size. On a small setup, dealing with remote access, passwords and separating uses brings far more, for far less.
Covered in : Sécurisation du réseau
Exposed directly to the internet, yes, it is one of the most exploited ways in. Routed through an encrypted tunnel with two-factor authentication, it becomes perfectly acceptable.
Covered in : Sécurisation du réseau
The review takes half a day. The priority corrections are often handled straight afterwards, the structural changes are then scheduled.
Covered in : Sécurisation du réseau
It adds some encryption, but the limiting factor is almost always the upload speed of the premises' connection. That is what we measure before committing.
Covered in : Installation VPN
Usually yes, a light VPN client, sometimes built into the system. It is configured once, after which connecting takes one click.
Covered in : Installation VPN
No. It secures the link, not the machines. An infected remote machine remains a danger to the network it joins, which is why we deal with both together.
Covered in : Installation VPN
It depends on the equipment and the available speed. Two or three occasional users work on most routers; beyond that, dedicated equipment is needed.
Covered in : Installation VPN
Not before measuring. If the speed obtained over a cable is already close to what you pay for, upgrading will change nothing: the problem is internal.
Covered in : Optimisation réseau
Yes, and it is common. A damaged pair drags a link down without cutting it, which makes the symptom hard to place without a test.
Covered in : Optimisation réseau
Half a day for an organization of ordinary size, measurements and report included. The free corrections are often made straight afterwards.
Covered in : Optimisation réseau
That is generally a matter of latency or occasional saturation, not of speed. The two are measured separately and corrected differently.
Covered in : Optimisation réseau
No. The contents are transferred in full, programs and settings included. The old disk is kept for a few days as a precaution before being returned to you.
Covered in : Passage au SSD
Not necessarily. The copy keeps the system as it is. A reinstall is only justified if the system was already unstable or infected.
Covered in : Passage au SSD
Generally half a day to a day, copying the data being the longest part. We agree the slot around your constraints.
Covered in : Passage au SSD
Yes, and it is recommended: the two jobs go well together and are done in a single visit. We check beforehand what the machine will accept.
Covered in : Passage au SSD
Half a day generally, longer if there is a lot of data or if many business programs have to be reinstalled.
Covered in : Installation de poste
Usually yes, with the original license. Some require deactivation on the old machine first: worth checking before parting with it.
Covered in : Installation de poste
Those saved in a synced browser come across automatically. The others are recovered before the transfer, a point we deal with from the outset.
Covered in : Installation de poste
Keep it for a few months as a precaution, then have it securely erased before giving it away, selling it or recycling it. Formatting alone does not protect your data.
Covered in : Installation de poste
No, quite the opposite: the components are standard, documented and replaceable one at a time. Reliability depends on the choice of parts, the power supply in particular.
Covered in : PC sur mesure
Yes, we assemble and install. We will simply point out any incompatibilities or choices that look unbalanced to us before starting.
Covered in : PC sur mesure
It is a separate license, which we supply and install. A license from a branded machine is generally not transferable.
Covered in : PC sur mesure
A few days depending on component availability. Assembly and installation take a day, supply determines the rest.
Covered in : PC sur mesure
It depends entirely on the monitor and the games in mind. We draw up two or three builds at different levels, explaining what each step up actually brings.
Covered in : PC gamer
There is a risk: unknown wear and no warranty. On a tight budget it remains a good lever, provided the rest of the machine is new.
Covered in : PC gamer
That is the whole point of custom building. We allow headroom on the power supply and leave memory slots free so upgrades stay simple.
Covered in : PC gamer
We put stability and quietness ahead of a few percent of performance. On request, we apply moderate settings verified under load.
Covered in : PC gamer
Almost always because its address changes every time the router restarts. Reserving a fixed address settles it for good, in a few minutes.
Covered in : Installation d'imprimante
No, not with a network printer: it works on its own. That only applies to a USB printer shared from a machine.
Covered in : Installation d'imprimante
For text and occasional use, a mono laser, because it does not dry out. For photos or a lot of color with regular use, inkjet still makes sense.
Covered in : Installation d'imprimante
Yes on most multifunction devices, and it is very handy in a business. It is also the function most often badly configured, particularly on access rights.
Covered in : Installation d'imprimante
There is no threshold: the need decides, particularly business software that requires one. Many ten-person organizations run perfectly well on a NAS.
Covered in : Installation de serveur
More than a NAS, and it makes noise. That is worth planning for: a server in an occupied office is rarely a good idea without a dedicated room or soundproofing.
Covered in : Installation de serveur
With redundant storage, work carries on while the disk is replaced. For a more serious failure, only a tested backup determines how long it takes to resume.
Covered in : Installation de serveur
It is strongly advised. An unmonitored server accumulates silent faults, starting with backups that have stopped and that nobody notices.
