Acer Laptops Acer Laptop Keyboard Some Keys Not Working: How to Fix It Yourself
When only some keys on an Acer laptop keyboard stop working, it's typically debris under the keys, a liquid spill residue, a driver issue, or a damaged keyboard ribbon cable. If an entire row or section is dead, the ribbon cable or keyboard circuit is likely the culprit.
⚠️ Safety First
- Turn off and unplug the laptop before cleaning the keyboard.
- Be gentle when removing keycaps — the scissor mechanisms underneath are fragile.
- If the keyboard stopped working after a spill, flip the laptop upside down immediately to drain.

Step-by-Step Repair
- 1
Identify the pattern of dead keys
Open a text editor and test every key on the keyboard. Use the on-screen keyboard (search 'On-Screen Keyboard' in Windows) to compare. Note which keys don't work. Are they random, in a row, or in a section? Random dead keys suggest debris. A whole row or column suggests a circuit or cable issue.
- 2
Clean under the affected keys
Turn off the laptop. Tilt it at a 45-degree angle and use compressed air to blow between and under the keys, moving across the keyboard. For stuck or dead individual keys, gently pry off the keycap with a keycap puller or thin flathead screwdriver. Clean underneath with a cotton swab and isopropyl alcohol. Snap the keycap back on.

Check for driver or software issues
Open Device Manager > Keyboards. Right-click your keyboard entry and select 'Uninstall device.' Restart the laptop — Windows will reinstall the driver automatically. Also check if Filter Keys is accidentally turned on: Settings > Accessibility > Keyboard > Filter Keys should be off.
- 4
Test with an external keyboard
Plug in a USB keyboard and test all the keys that aren't working on the built-in keyboard. If the same keys don't work on the external keyboard, it's a software issue. If the external keyboard works perfectly, the built-in keyboard hardware is the problem.
- 5
Replace the keyboard
If cleaning and drivers didn't help and an entire section is dead, the keyboard needs replacing. On most Acer laptops, the keyboard is held in by screws from the bottom and clips from the top. Remove the back panel, disconnect the keyboard ribbon cable from the motherboard, unscrew the keyboard, and swap it. Order by exact Acer model number.
If That Didn't Work
- Liquid spill damage corroding the key contacts
- Windows Sticky Keys or Filter Keys accidentally enabled
- Keyboard ribbon cable came loose from the motherboard connector
- Physical damage from heavy impact
When to Call a Professional
If the keyboard replacement doesn't fix it, the motherboard keyboard connector may be damaged. A technician can inspect and repair the connector.
