How to Fix a Laptop Keyboard That Is Not Working
Is your laptop keyboard unresponsive or typing the wrong characters? A non-working keyboard can be frustrating, but it doesn’t always mean you need a replacement. This guide will show you easy troubleshooting steps to fix a laptop keyboard that’s not working.
1. Check for Dirt and Debris
Dust and crumbs can block key movement, causing unresponsiveness.
✔ Turn the laptop upside down and gently shake it to remove loose debris.
✔ Use compressed air to clean under the keys.
✔ For sticky keys, clean them with a cotton swab and rubbing alcohol.
🛑 Do not use excessive liquid while cleaning.
2. Restart Your Laptop
Sometimes, a simple restart can fix temporary glitches.
✔ If your keyboard isn’t working at all, use an external USB keyboard to restart the laptop.
✔ Try booting into Safe Mode (Windows: Shift + Restart | Mac: Hold Shift while booting) to see if the keyboard works.
3. Check Keyboard Connection (For Detachable Keyboards)
If you have a 2-in-1 laptop or a detachable keyboard, the connection might be loose.
✔ Disconnect and reconnect the keyboard.
✔ Look for dust or damage in the connection port.
4. Update or Reinstall Keyboard Drivers (Windows Only)
Outdated or faulty drivers can cause keyboard malfunctions.
- Open Device Manager (Win + X > Device Manager).
- Expand Keyboards, right-click your keyboard, and select Update Driver.
- If updating doesn’t work, select Uninstall Device and restart your laptop.
🛑 Windows will reinstall the keyboard driver automatically.
5. Disable Filter Keys (Windows Only)
Filter Keys can cause slow or unresponsive keyboard input.
- Go to Control Panel > Ease of Access > Keyboard Settings.
- Turn off Filter Keys and restart your laptop.
6. Test Keyboard in BIOS Mode
If your keyboard doesn’t work in Windows but does in BIOS, it’s a software issue.
✔ Restart the laptop and press F2, F10, or DEL to enter BIOS.
✔ If the keyboard works here, Windows may be the problem.
✔ Try System Restore or reinstall the operating system if needed.
7. Check for Physical Damage
A damaged keyboard may need replacement.
✔ If some keys work but others don’t, the keyboard membrane may be broken.
✔ If the keyboard types automatically, there may be a short circuit.
✔ Try using an external USB keyboard – If it works fine, the built-in keyboard may need repair.
🛑 If the keyboard is physically damaged, replacement is the only option.
Final Thoughts
A non-working keyboard can often be fixed with simple troubleshooting. Before considering a replacement, try cleaning, updating drivers, and checking for software issues. If your keyboard is physically damaged, replacing it is the best long-term solution.
