What to do when your laptop keyboard stops typing, types the wrong characters, or loses a few keys.
Quick answer: If your laptop keyboard is not working, restart the laptop and check that Filter Keys is off in Windows Settings. Then reinstall the keyboard driver in Device Manager. To learn whether the fault is software or hardware, open the BIOS at start-up: if the keys work there, Windows is the problem. If they do not, the keyboard or its connection has probably failed.
A laptop keyboard is hard to replace on the spot, so a dead one can stop your work right away. Fortunately, plenty of keyboard faults come from Windows settings and drivers rather than the keyboard itself.
This guide shows you how to keep working while you fix it, how to separate a software problem from a hardware one, and which repairs are worth paying for. All the Windows paths below are for Windows 11.

How can you keep working while the keyboard is broken?
You need a way to type before you can try most fixes. There are two easy options.
- Use the on-screen keyboard: Press Windows + Ctrl + O, or use your mouse to open Settings > Accessibility > Keyboard and turn on the on-screen keyboard.
- Plug in a USB keyboard: Any cheap wired keyboard will do. If it works, the laptop itself is responding normally to keyboard input, and the fault is limited to the built-in keys or their driver.
Is it a software or hardware problem?
Restart the laptop and tap the BIOS key right after you press power. It is often F2, F1, F10 or Delete, depending on the maker. If the BIOS opens and the arrow keys move around the menu, the keyboard is physically working. Exit without saving, and focus on Windows.
| What you notice | Likely cause | Best next step |
|---|---|---|
| All keys dead in Windows, fine in BIOS | Driver or Windows setting | Fix 2 to Fix 7 |
| All keys dead everywhere | Failed keyboard or loose cable | Fix 10 |
| A few keys dead, others fine | Debris or worn switches | Fix 8 |
| Numbers appear instead of letters | Num Lock or Fn Lock | Fix 3 |
| Keys stopped after a spill | Liquid damage | Fix 9, and power off now |
What are the fixes for a laptop keyboard that is not working?
1. Restart properly
Use Start, then Power, then Restart. A restart reloads the keyboard driver in full. If that fails, shut down, disconnect accessories, wait 30 seconds, and start it again.
2. Turn off Filter Keys
Filter Keys makes Windows ignore short or repeated key presses, and it can switch on by accident if you hold Shift for several seconds. Go to Settings > Accessibility > Keyboard and turn off Filter keys. Check Sticky keys on the same page too.
Ana thought her keyboard had died because letters only appeared when she held each key down for a second. She had leaned on the Shift key during a video call, and that switched on Filter Keys. Turning it off fixed the whole keyboard in under a minute.
3. Check Num Lock and Fn Lock
On smaller laptops, Num Lock can make letter keys type numbers. Press Num Lock once to test this. Function keys may also act differently when Fn Lock is on. Many laptops toggle it with Fn + Esc, though it varies by model.
4. Reinstall the keyboard driver
Right-click Start and open Device Manager. Expand Keyboards, right-click your keyboard, and choose Uninstall device. Restart the laptop, and Windows will reinstall the driver when it starts. You can also choose Update driver and search automatically.
5. Stop Windows from powering down the keyboard
In Device Manager, open your keyboard’s Properties and go to the Power Management tab, if there is one. Uncheck “Allow the computer to turn off this device to save power” and click OK.
6. Turn off Fast Startup
Fast Startup keeps part of the system in a saved state, which can carry a driver fault across restarts. Open Control Panel > Power Options > Choose what the power buttons do. Click Change settings that are currently unavailable if the box is grey, uncheck Turn on fast startup, and save.
7. Remove a recent Windows update
If the keyboard stopped straight after an update, go to Settings > Windows Update > Update history > Uninstall updates. Remove the latest update and restart. If everything is working, you can pause updates for a short time while you wait for a corrected version. Also install any updates from your laptop maker’s support tool, since a chipset or BIOS update can solve input faults.
8. Clean the keyboard
Shut the laptop down first. Tilt it and use short bursts of compressed air around any stuck keys. Crumbs and dust can stop a key from making contact. Avoid forcing keycaps off, because the small clips underneath break easily.
9. Deal with a spill quickly
Turn the laptop off right away and unplug the charger. Turn it upside down and let it drain. Do not switch it on to test it. Liquid can keep causing damage inside after the keys appear to dry, so have it checked by a technician if the spill was more than a few drops, or if it was sugary.
10. Check for a loose connection or failed keyboard
If the keys fail in the BIOS as well, the keyboard or its ribbon cable has probably failed. This often happens after a drop, a spill or a recent repair. At that point, it is a job for a technician unless you are comfortable opening laptops.
Note which keys fail before you book a repair. If they sit in a single row or a block, it can point to a damaged keyboard circuit, and the technician can test that first. A short list of symptoms saves time and often money.
What does a keyboard repair cost and is it worth it?
Prices depend on the model. Some laptops let a technician swap the keyboard with a few screws, whereas others have it fixed to the top case, which means replacing a larger and more costly part. Ask for a written quote, and check your warranty first.
If the quote is high and you mostly work at a desk, an external keyboard is a sensible low-cost alternative. It will not help much when you travel, but it can extend the life of an otherwise healthy laptop by years.
A small business owner’s four-year-old laptop lost its top row of keys. The repair needed a full top case, so she bought a compact Bluetooth keyboard for her desk and saved the repair money towards her next laptop.
What are the risks and limits of these fixes?
- Uninstalling a driver: This is safe in most cases because Windows reinstalls it, but keep a USB keyboard or the on-screen keyboard ready.
- Removing updates: An update can include security fixes, so reinstall it once a corrected version arrives.
- Removing keycaps: Clips and scissor mechanisms break easily and can be hard to replace.
- Drying a wet laptop with heat: A hair dryer can warp parts and push liquid further inside. Let it air-dry and get it checked.
Open the on-screen keyboard now with Windows + Ctrl + O so you remember how it works, then close it. Add a cheap USB keyboard to your desk drawer if you rely on your laptop for income.
Frequently asked questions
Why did my laptop keyboard suddenly stop working?
Common causes are a driver glitch, a recent update, Filter Keys being switched on, or physical damage from a drop or spill. Start with a restart, and then check the Windows settings.
How do I turn my laptop keyboard back on?
Reinstall the driver from Device Manager, turn off Filter Keys, and check for a function key that locks the keyboard on some models. Restarting often reloads it as well.
Why are only some keys not working on my laptop?
Usually debris, worn switches or liquid damage. Clean it with compressed air. If a whole row or block fails, the keyboard circuit may be damaged.
Why does my keyboard type numbers instead of letters?
Num Lock is probably on. Press Num Lock, or Fn with the key that shows a Num Lock icon, to switch it off.
Can I use my laptop with a broken keyboard?
Yes. A USB or Bluetooth keyboard works straight away, and the on-screen keyboard is there for short tasks.
Is it worth replacing a laptop keyboard?
Usually yes on a newer laptop, especially if the keyboard is a simple swap. On an older model, compare the quote with an external keyboard or a replacement laptop.
Final Thoughts
- Use the BIOS test first. It tells you whether to work on Windows or book a repair.
- Check Filter Keys and Num Lock before you assume that anything is broken.
- Turn the laptop off at once after a spill, and do not test it until it has been checked.
- Keep a USB keyboard as a cheap backup for urgent work.
