A Few Keys Stopped Working? Try This First.

When a key — or a handful of keys — stops responding, it's frustrating, but it's rarely serious and often free to fix. Let's rule out the simple causes before assuming anything is broken.

1. Restart the Laptop

You'll have heard this before, and for good reason: a restart clears little glitches that can leave keys unresponsive. Start → Power → Restart, then test the keys again.

2. Check for Crumbs and Dust

It's the commonest cause of all. A crumb or speck of dust under a key stops it pressing properly.

  • Switch the laptop off.
  • Turn it upside down over a bin and give it a gentle shake.
  • A puff of compressed air around the sticky keys works wonders.
Was something spilt?

If tea, coffee or water has gone near the keyboard, switch the laptop off straight away, unplug it, and don't use it until it's completely dry. Liquid and electronics don't mix — and this is a good moment to ask us before switching it back on.

3. Make Sure It Isn't a Setting

Occasionally a setting is the culprit rather than the key:

  • If numbers aren't typing on the right-hand keys, press the Num Lock key once.
  • If pressing keys does nothing in one programme but works elsewhere, the programme — not the keyboard — is frozen. Close and reopen it.

4. A Free Way to Keep Going Meanwhile

If a key fails just when you need it, Windows has a built-in On-Screen Keyboard you can click with the mouse — a handy stand-in until the real one is sorted. Press the Windows key, type On-Screen Keyboard, and open it.

5. Update the Keyboard Driver

If several keys misbehave, the keyboard's driver (its instruction software) may need refreshing. Your laptop maker's free tool — HP Support Assistant, Dell SupportAssist or Lenovo Vantage — will handle it. Open it, check for updates, and restart.

Still not right? We'll take a look

Ask our IT Man — free and friendly. Tell us which keys are affected and whether anything was spilt. If it turns out the keyboard needs replacing, it's usually an inexpensive fix — and we'll tell you honestly before you spend anything.

In a Nutshell

Most "dead" keys are just a glitch or a crumb. Restart, give the keyboard a gentle clean, and check Num Lock. The free On-Screen Keyboard keeps you going in the meantime. If a spill was involved — switch off and ask us before powering back on.
