Laptop Keyboard Not Working? Fixes, Then When to Call
Most laptop keyboards that stop typing have a cause you can find in about fifteen minutes: a switched-on accessibility setting, a stuck driver, crumbs under a key, or a spill. If none of those turns out to be the cause, the fault is physical, and a hardware repair is the answer. Work through the checks below in order. We’ll point out where each one goes wrong, and where our technicians at NextGen IT can come to your home in Brisbane, Logan, Ipswich or Redlands and sort it for you, on a No Fix, No Fee basis.
TL;DR
Restart first, and unplug anything attached (USB devices, docks, external monitors). A confused peripheral can make a built-in keyboard look dead.
If only some keys fail, or letters type as numbers, check Filter Keys, Sticky Keys and Num Lock before you suspect hardware.
Plug in an external keyboard. If it works, the problem is limited to the laptop’s own keyboard. If it also fails, the cause is almost certainly in Windows.
Liquid on the keyboard is an emergency: shut the laptop down straight away and keep it off.
A whole row or column of dead keys, or keys that fail on and off, usually points to hardware. That is the point to stop troubleshooting and book a repair.

Start with the quick checks
Before you open a single setting, spend two minutes on the basics. They fix more keyboards than any driver reinstall.
Restart the laptop properly. Use Restart from the Start menu, not just closing the lid. A restart clears a stuck software state that can stop the keyboard from sending input. If you can’t type a password to get in, use the on-screen keyboard (the small keyboard icon at the bottom right of the Windows sign-in screen) and click the letters with your mouse or trackpad.
Disconnect everything. Unplug USB devices, external monitors, wireless dongles and any docking station, then restart. Manufacturers such as Dell recommend exactly this step, because a faulty accessory can interfere with input. If the keyboard comes back, reconnect your devices one at a time to find the culprit.
Check the obvious physical things. Is the laptop in tablet or tent mode (on a 2-in-1)? Some models switch the keyboard off when the screen is folded back. Is a heavy case, cover or sleeve pressing on the keys? Has someone stuck a cover or protector over the keyboard that has shifted?
Note exactly what is wrong. The pattern tells you where the fault lives:
What you see | Most likely cause | Go to |
Nothing types at all, even after a restart | Driver, Windows setting or hardware connection | Driver and test sections |
Keys respond slowly or you must press hard | Filter Keys switched on | Accessibility settings |
Letters type as numbers (e.g. J types 1) | Num Lock or an Fn function lock | Num Lock section |
One or a few keys dead | Debris under the key, or a damaged key | Cleaning section |
A whole row or column dead | Damaged keyboard connector or matrix | When to call a technician |
Keys type by themselves, or keyboard died after a spill | Liquid damage | Spill section |
How to unlock or unfreeze a laptop keyboard
People often search for how to “unlock” a laptop keyboard, but laptops rarely have a true lock. What looks like a locked keyboard is almost always one of three things: an accessibility feature that has been switched on by accident, a function key combination, or a frozen Windows session.
Filter Keys, Sticky Keys and Toggle Keys
Windows has accessibility features that change how the keyboard behaves. Filter Keys tells Windows to ignore brief or repeated keystrokes. If it is on, you may find you have to hold each key down for a moment before a character appears, which feels exactly like a dying keyboard. Sony’s support guidance notes these features can be turned on unintentionally, and ASUS points to Filter Keys as the cause when keys feel insensitive or delayed.
The usual accident is holding the Shift key down for several seconds, which pops up a prompt offering to turn Filter Keys on. Someone presses Enter or clicks Yes without reading it, and the keyboard changes behaviour.
To check and switch these off in Windows 11:
Open Settings (Windows key + I, or use the mouse on the Start menu).
Go to Accessibility, then Keyboard.
Turn off Sticky keys, Filter keys and Toggle keys.
Test the keyboard in Notepad.
On Windows 10 the same switches live under Ease of Access, then Keyboard. If you can’t type at all, you can do all of this with the mouse.
Where this goes wrong: the shortcut that turns the feature on can also be left enabled in a sub-menu, so it switches itself back on. Open the “Keyboard shortcut for…” options and untick the shortcut for each feature, so it can’t happen again.
Num Lock and function lock
If letters are typing as numbers, especially on the right side of the keyboard (M, J, K, L, U, I, O), Num Lock is on and the embedded number pad is active. Look for a Num Lock light, then press Num Lock, or use an Fn key combination if your model has no dedicated key. ASUS lists this as one of the most common causes of a “locked” keyboard.
Similarly, if the volume, brightness or other top-row keys do the opposite of what you expect, a function lock (often Fn plus Esc) has been toggled. Press that combination once and try again.
Unfreezing a keyboard that has stopped responding mid-session
If the keyboard dies while you are working and nothing else on screen is moving either, Windows itself may have frozen. Try these in order:
Wait a minute. A busy laptop that is running updates or a heavy program can ignore input for a short time.
Press Ctrl + Alt + Delete. If that screen appears, Windows is alive. Use the mouse to open Task Manager, end the program that is not responding, or choose Restart from the power icon.
If even Ctrl + Alt + Delete does nothing, hold the power button until the laptop shuts down, wait ten seconds, then start it again. Save work first whenever you can, because a forced shutdown loses anything unsaved.
If the screen freezes along with the keyboard regularly, you have a bigger problem than keys. A laptop that hangs often may have a failing drive, overheating or malware, and that deserves a proper diagnosis.
Test whether it is software or hardware
The single most useful test costs nothing if you have a spare keyboard. It splits the problem cleanly in two.
The external keyboard test
Plug in a USB keyboard, or pair a Bluetooth or wireless one. Dell advises that if the external keyboard works, the issue is limited to the laptop’s built-in keyboard. That tells you the rest of the laptop is processing input fine, so the fault is either the built-in keyboard’s driver or its hardware.
If the external keyboard fails too, Windows is the problem, not the keys. Move on to the driver steps below. For USB keyboards, plug straight into a port on the laptop rather than through a hub, and try another port, as HP’s guidance suggests.
Does the keyboard work before Windows loads?
Restart the laptop and tap the key that opens the BIOS or UEFI setup screen as it starts. The key varies by brand and is usually shown on the start-up logo screen (commonly F2, Delete, F10 or Esc). If the built-in keyboard moves the menu selection there, the keyboard hardware is working and the fault sits in Windows, either a setting or a driver. If it does not respond at all in that screen, a hardware fault becomes much more likely.
Where this goes wrong: timing. On many laptops you have a second or two to press the key, and Windows’ fast start-up can skip it. Shut down fully (hold Shift while clicking Shut down), then power on and tap the key repeatedly. If you can’t find the right key for your model, that is an easy thing for a technician to check on the spot.
Reinstall the keyboard driver
A corrupted driver can stop a built-in keyboard working even though the hardware is fine. Dell and ASUS both describe the same approach:
Right-click the Start button and choose Device Manager (or press Windows key + X).
Expand Keyboards.
Right-click the keyboard entry (often “Standard PS/2 Keyboard” on laptops) and choose Uninstall device.
Restart. Windows reinstalls the driver automatically.
If you can’t type, navigate Device Manager with the mouse. If an entry shows a yellow warning triangle, the driver is clearly the problem.
Where this goes wrong: people uninstall the wrong item, or uninstall several drivers at once and end up with a trackpad that has stopped too. If the trackpad also misbehaves, our guide to fixes to try for a trackpad that isn’t working covers the matching checks. Outdated system drivers and BIOS can also cause keyboard faults, so Windows Update and your manufacturer’s update tool are worth running, but a BIOS update done wrongly can leave a laptop unable to start. It is not a step to take casually.
Run the Windows keyboard troubleshooter
In Windows 11, open Settings, then System, then Troubleshoot, then Other troubleshooters, and run the Keyboard troubleshooter, as ASUS describes. It is quick and occasionally catches a setting you missed, though it often reports that it found nothing.
Roll back a recent change
If the keyboard failed right after an update or new software, use System Restore to return to a restore point from before the problem started. ASUS suggests this for recently started faults. Search “Create a restore point” in the Start menu, then choose System Restore. Your documents are not touched, but programs installed since that point are removed.
Only some keys not working
When most of the keyboard types normally and a handful of keys are dead, the suspects change. Software rarely kills three random keys. Dirt and physical wear do.
Clean the keys properly
Dust, crumbs, hair and dried drink residue can hold a key partly down or stop it making contact. Both Dell and Microsoft tell users to make sure nothing is blocking the keys. Here is the safe routine:
Shut the laptop down and unplug the charger. Dell’s guidance is to turn the computer off before cleaning around a problem key.
Tilt the laptop at an angle and use compressed air in short bursts along the rows of keys.
Wipe the key surfaces with a soft microfibre cloth, lightly dampened if there is grime. Never spray liquid onto the keyboard.
Test the keys again in Notepad.
Where this goes wrong: prying off keycaps. Laptop keycaps sit on tiny plastic clips that snap easily, and a broken clip turns a dirty key into a dead key. Different models use different mechanisms, and the thin keyboards in modern ultrabooks are especially fragile. If a key still feels gritty or stuck after a blast of air, leave the cap alone.
Rule out a stuck or sticky key causing the rest
A key held down by debris can make other keys misbehave, or fill a document with repeated characters. Open Notepad and press each problem key slowly. A key that feels spongy, doesn’t spring back or clicks differently from its neighbours is mechanically damaged, not misconfigured.
Check the keyboard layout and language
If keys type the wrong characters (an @ where a quote should be, or a £ where a # should be), the keyboard layout is probably set to another region. In Settings, go to Time & language, then Language & region, and make sure English (Australia) is the one in use and that its keyboard layout is selected. Press Windows key + Space to cycle through installed layouts. Accidentally pressing that shortcut is a very common reason for symbols moving around.
If liquid has been spilled on the keyboard
Liquid changes everything, because the damage continues after the spill and can reach the motherboard. Do these things immediately:
Shut the laptop down at once. Hold the power button if you have to. Don’t wait to save a document.
Unplug the charger and remove any accessories.
Turn the laptop upside down in a tent shape to let liquid drain away from the electronics, then dab the surface with a soft microfibre cloth.
Leave it to dry thoroughly. Dell’s advice is to allow at least 24 to 48 hours before switching it on.
Don’t use a hairdryer, don’t put it in rice, and don’t power it on to “see if it works”. Sweet, sticky or milky liquids (tea with sugar, juice, soft drink, coffee with milk) are worse than clear water because they leave residue that keeps shorting contacts as they dry. A university IT support team, NMU’s Technology Support Services, advises that for greasy or sticky liquids the device should go to an authorised service provider rather than simply air-drying.
Our step-by-step guide to saving your laptop in the first 5 to 15 minutes after a spill goes into the timing in more detail. If the laptop has had a drink on it and the keyboard now misbehaves, a technician should open it, check for corrosion and confirm the data is safe. Data recovery is part of what we do, so if the laptop won’t start after a spill, say so when you book and we will take the drive into account.
When to stop troubleshooting and get it repaired
There is a point where more clicking in Settings is wasted effort. Stop when you see any of these:
A whole column or row of keys is dead, or keys work intermittently in a block. That pattern typically points to a damaged keyboard matrix or ribbon connector, and Microsoft’s own community guidance, a Q&A answer on a dead column of keys, describes it as needing a hardware repair, with an external keyboard as the stopgap.
The keyboard doesn’t work in the BIOS or UEFI screen, and the external keyboard works fine in Windows.
The laptop has been dropped, crushed or spilled on and the keyboard failed afterwards.
The driver reinstall, troubleshooter and restore all made no difference.
The keys feel loose, lifted or swollen. A bulging battery can push the keyboard upward from underneath. Don’t press on it or keep charging it. Read our guide to laptop charging port problems, including swollen batteries and turn the laptop off.
Resetting Windows is a last software step some manufacturers mention, and ASUS advises backing up your personal files first. A reset takes hours, wipes your set-up and still won’t fix a hardware fault, so it is rarely worth starting without a clear sign the problem is in Windows. If the external keyboard works perfectly and the BIOS test fails, a reset won’t help.
If the laptop shows other symptoms too, such as not starting at all, our guide on mapping what you see to the fault when a PC won’t turn on may point you to the real cause.
Use an external keyboard in the meantime
A cheap USB or Bluetooth keyboard keeps you working while you wait for a repair. It also keeps you from making matters worse by hammering at dead keys or opening the laptop yourself. For urgent jobs, such as a work deadline or a bank login, the on-screen keyboard (Windows key + Ctrl + O) gets you through a password prompt in a pinch.
Who fixes a laptop keyboard at home in Brisbane
This is the part of the job most people dread: working out whether to try another fix, carry the laptop into a shop and leave it for days, or live with the problem. A technician coming to you changes that. Our technicians are local, patient and explain what they find in plain English, with no jargon.
When you book our laptop and computer repairs, a technician comes to your home, and we cover hardware and screen repairs, slow computers, virus and malware removal and data recovery. Pricing is fixed and given upfront after assessment, with no hidden fees, and our No Fix, No Fee guarantee means you pay only when the problem is solved. We offer same-day home visits, which suits anyone who can’t be without their laptop for a week.
We serve Brisbane, Ipswich, Redlands and Logan. If your laptop is a Windows machine, our Microsoft, Windows and Surface support covers it, and Mac owners can see our Apple support page.
To make a visit quick, have these details ready: the make and model, what you’ve already tried, whether the problem started after a spill, drop or update, and whether anything on the laptop is irreplaceable. Writing down which keys fail, and whether the external keyboard works, saves the technician time.
Prevent keyboard trouble
Keep drinks away from the laptop. Most keyboard deaths we hear about follow a spilled cup. Even a small splash is worth treating as a spill.
Close the lid gently and don’t leave pens, earbuds or cables on the keyboard when you do. They leave marks on the screen and can press keys down.
Clean every month or two with compressed air, with the laptop off.
Keep Windows updated, so keyboard drivers stay current. If you’re unsure which updates matter, we can look at it during a visit.
Make backups. A failed keyboard is annoying. A failed keyboard on a laptop with the only copy of your photos and documents is a bigger problem.
FAQ
How do I fix my laptop keyboard that is not typing?
Restart, unplug all accessories, then check Filter Keys, Sticky Keys and Num Lock in Windows settings. Next, reinstall the keyboard driver in Device Manager and test with an external keyboard. If that works but the built-in keys still don’t, the fault is in the laptop’s keyboard hardware and needs a repair.
How do I unlock a laptop keyboard?
Most laptops don’t have a real lock. Turn off Filter Keys and Sticky Keys in the Windows keyboard accessibility settings, press Num Lock if letters type as numbers, and check for a function lock key combination. If your keyboard still won’t respond, move on to the driver and hardware checks.
Why are only some keys on my laptop not working?
Crumbs, dust and dried spills under the keys are the usual cause, followed by a damaged key or a loose keyboard connector. Switch the laptop off and clean around the keys with compressed air. If a whole row or column is dead, that points to hardware, so book a repair rather than keep troubleshooting.
Can I accidentally lock my keyboard?
Yes. Holding Shift down for several seconds can switch on Filter Keys, which delays or ignores keystrokes. Num Lock, a function lock or a changed keyboard layout can make a working keyboard seem faulty too. Each of these takes a minute to check and undo in Settings.
Is it worth repairing a laptop keyboard?
Often yes, particularly when the rest of the laptop is in good order. A repair is usually much cheaper than replacing the laptop. A technician can confirm whether it’s the keyboard, the connector or something deeper before you commit to anything, and with our No Fix, No Fee guarantee you only pay if it is fixed.
