Laptop Keyboard Not Working? Causes, Quick Fixes & When to Replace

A laptop keyboard can fail in many ways, one dead key, a whole row gone, or nothing typing at all. Some causes are simple to fix; others mean the keyboard needs replacing. Here's how to tell.

1. Restart first

A temporary software glitch can freeze a keyboard. A simple restart is always worth trying before anything else, and it costs nothing.

2. Clean stuck or unresponsive keys

Crumbs, dust and debris under the keys are a common cause of stuck or non-responding keys. Carefully cleaning around them can bring them back.

3. Reinstall the keyboard driver

On Windows, a corrupt keyboard driver can stop input. Removing and reinstalling it through Device Manager fixes some cases, especially if the trouble started after an update.

4. Spill damage

Liquid is the number-one killer of laptop keyboards. Even a small spill can corrode the contacts, causing keys to fail days or weeks later. If keys stopped working after any spill, the keyboard has likely been damaged.

5. A loose ribbon connector

After a drop or a previous repair, the keyboard's ribbon cable to the motherboard can come slightly loose, knocking out part or all of the keyboard. Re-seating it can restore function.

6. When to replace

If multiple keys are dead, the keyboard has spill damage, or cleaning and drivers don't help, replacement is the reliable fix. In the meantime, a plug-in USB keyboard keeps you working.
