Laptop Keyboard Not Working? Causes & Fixes

A laptop keyboard that won't type, has dead keys, or repeats letters is frustrating — but it's also one of the more fixable problems we handle. The right repair depends entirely on whether the issue is software or hardware, so a proper diagnosis comes first.

Common keyboard problems

Most keyboard faults we see fall into a few groups:

• Dead keys — one or more keys do nothing when pressed.
• Stuck or sticky keys — keys that don't spring back or feel gummy.
• Whole keyboard unresponsive — nothing types at all.
• Ghost typing — letters repeat or appear on their own.

Liquid spills: act fast

Chai, water, or a cold drink over the keyboard is a very common cause, and timing matters enormously. If you spill liquid, switch the laptop off immediately, unplug it, remove the charger, and turn it upside down to drain. Do not keep using it and do not try to dry it with heat. Liquid can corrode the keyboard and seep down to the motherboard and storage drive, so the sooner it's opened and cleaned, the better the outcome. Sugary drinks are especially damaging as they leave a sticky residue that keeps eating at the contacts. If a spill has put your files at risk, our data recovery team can step in alongside the repair.

Driver issue or hardware fault?

Not every keyboard problem is physical. Sometimes a driver glitch or software setting is to blame, and a simple restart, driver reinstall, or settings check fixes it for free. A quick way to tell: if an external USB keyboard works perfectly but the built-in one doesn't, the fault is usually hardware. If both behave oddly, it may be software. Our technicians check the software side first before recommending any part replacement.

How we fix it

Once we've diagnosed the cause, the repair is straightforward:

• Clean under stuck keys or clear spill residue.
• Reinstall or update keyboard drivers if it's a software issue.
• Replace the keyboard module if keys are physically dead.
• Inspect the board for any liquid damage underneath.
