Some Laptop Keys Stopped Working?
Common Keyboard Problems — and What to Check First
Have some keys on your laptop keyboard suddenly stopped working?
A laptop keyboard problem does not always mean the keyboard itself has failed. The cause could be dirt or liquid under the keys, a damaged keyboard, a loose internal connection, a driver or software problem, a stuck modifier key, or another hardware fault.
The pattern of affected keys and whether the problem occurs everywhere can provide important clues.
In this guide, we explain common causes, what you can check safely, and when professional diagnosis or keyboard replacement may be needed.
Different keyboard problem need different fixes
Some keys do not work at all
Some keys do not work at all (no pattern)
One or more specific keys, such as R or E, do not produce any input when pressed, while other keys continue to work normally. This is commonly caused by physical damage or wear to the keyboard, although the underlying keyboard circuitry or connection may also be responsible.
Certain keys or a row of keys stopped working
Certain group or rows of keys stopped working (has a pattern)
If an entire row, column, number pad, or another group of keys stops working while other keys function normally, this may indicate a keyboard hardware or connection problem. It is commonly caused by a faulty keyboard connection, damaged keyboard circuitry, or a problem with the keyboard itself.
Keys work intermittently
Keys work intermittently
A key may work intermittently or only register when pressed at a particular angle or with a certain amount of pressure. This usually indicates a physical problem with the key mechanism or its connection, such as a worn or damaged key switch, keycap mechanism, or underlying keyboard contact.
Keys type the wrong characters

The keyboard may be using an incorrect keyboard layout, or a software or accessibility setting may be affecting how keystrokes are interpreted. Please check the computer's keyboard and input settings to make sure the correct layout and input options are selected.
Some keys feel physically damaged or stuck
Some keys feel physically damaged or stuck
A key may feel loose, broken, sticky, or difficult to press due to normal wear and tear, physical impact, or liquid exposure. This may indicate damage to the keycap, key mechanism, or the underlying keyboard assembly.

Liquid exposure or physical impact can damage the keyboard, its internal connectors, or other related components. Depending on the severity of the damage, the keyboard may become partially or completely unresponsive.

If the keyboard works normally in BIOS/UEFI or at the login screen but stops working after Windows or macOS starts, the problem may be related to drivers, software, or system settings. Similarly, if the keyboard works in Safe Mode but not in normal mode, or the problem occurs only in a specific application, the cause is more likely to be software-related rather than a physical keyboard fault.
Common Causes of Laptop Keyboard Problems
- Dust, dirt or debris — Debris under or around a key can prevent the key mechanism from working correctly.
- Liquid damage — A spill can affect individual keys, keyboard circuits or the internal connector.
- Physical damage or wear — A damaged key mechanism, keyboard membrane or worn keyboard can cause individual keys to fail.
- Loose or damaged keyboard connection — The internal keyboard cable or connector may be loose or damaged.
- Keyboard driver or software problem — Windows or macOS may not be handling keyboard input correctly.
- Wrong keyboard layout or language — The keyboard may produce unexpected characters rather than simply failing.
- Accessibility or keyboard settings — Settings such as Filter Keys or related features can change keyboard behaviour.
- Motherboard or embedded-controller fault — Less commonly, the keyboard circuit or system hardware may be responsible.
What to Do When Some Laptop Keys Stop Working?
On Windows
Including Windows 10 and Windows 11 laptops from different manufacturers and with built-in keyboards.
Try these checks before replacing the keyboard:
1. Check the basics- Restart the laptop and test the affected keys again.
- Check whether the keys are physically stuck, loose or obstructed by debris.
- If there has been a liquid spill, stop using the laptop and avoid repeatedly powering it on.
- Test several nearby keys and note whether there is a pattern, such as one row or column.
- Try typing in Notepad or another simple text field.
- Test an external USB or Bluetooth keyboard if available.
- Check whether the affected keys work at the Windows sign-in screen or in BIOS/UEFI if accessible.
- Check the keyboard language and layout in Windows Settings.
- Check accessibility settings such as Filter Keys if keyboard behaviour is unusual.
- In Device Manager, check the keyboard device and consider updating or reinstalling its driver if appropriate.
- If only the built-in keyboard is affected, the keyboard, cable or motherboard may need inspection or replacement.
- If the laptop has suffered liquid damage, professional inspection is recommended because corrosion can cause additional problems later.
On a Mac
Including recent macOS versions and different MacBook models with built-in keyboards.
Try these checks before replacing the keyboard:
1. Check the basics- Restart the Mac and test the affected keys again.
- Check whether the keys are physically stuck, loose or obstructed by debris.
- If there has been a liquid spill, stop using the Mac and avoid repeatedly powering it on.
- Test several nearby keys and note whether there is a pattern.
- Test typing in TextEdit or another simple text field.
- Try an external keyboard if available.
- Test whether the affected keys work at the Mac login screen or in another startup environment if accessible.
- Check the keyboard input source and language settings.
- Check whether any accessibility settings are affecting keyboard input.
- If only the built-in keyboard is affected, the keyboard, connector or other hardware may need inspection.
- After liquid exposure, professional inspection is recommended even if some keys still work.
When Should You Stop Troubleshooting?
- Several keys or an entire row/column have stopped working suddenly.
- The keyboard stopped working after liquid exposure, a drop or another physical incident.
- The keys are physically damaged, loose or stuck.
- An external keyboard works but the built-in keyboard does not.
- You are considering opening the laptop or replacing the keyboard but are unsure how it is connected.
- The keyboard problem is accompanied by other hardware symptoms such as random shutdowns or charging problems.
Common questions
Why have some of my laptop keys stopped working?
Why does an entire row or group of laptop keys stop working?
Could liquid damage cause only some keys to stop working?
Could a keyboard driver or Windows/macOS setting cause this problem?
Can I clean a laptop keyboard when some keys are not working?
Can the laptop keyboard be replaced?
Can I replace the laptop keyboard myself?
If you are purchasing a replacement keyboard yourself, make sure you check the exact laptop model, keyboard part number and layout before ordering. Even very similar laptop models can use different keyboards, connectors or layouts, so a keyboard designed for a similar model may not be compatible with your laptop.
If you are unsure which keyboard you need or whether the replacement is compatible, we recommend checking the laptop model and part number before purchasing.
Don’t Remove Keycaps by Force!
When a few laptop keys stop working, it can be tempting to remove the keycaps or open the laptop immediately. Laptop keyboard mechanisms are delicate, and forcing a key can damage the keycap, hinge or keyboard.
Before attempting a physical repair, identify the affected keys, test an external keyboard, check for liquid or physical damage, and back up important data.
