Short answer

Dirt under a key, a wrong keyboard language, or a sticky keys setting explain most cases before hardware failure does. The quickest thing to try first: check the language layout — If pressing the at symbol gives quotation marks, the layout is wrong. Press Windows and Space to switch, or set the correct layout in Settings, Time and language. Most people are done in about 15 minutes.

  • Keys repeat by themselves

Why it happens

Dirt under a key, a wrong keyboard language, or a sticky keys setting explain most cases before hardware failure does.

Work through these in order

0% done
  1. 1

    Check the language layout

    If pressing the at symbol gives quotation marks, the layout is wrong. Press Windows and Space to switch, or set the correct layout in Settings, Time and language.

  2. 2

    Turn off the accessibility settings

    Open Settings, Accessibility, Keyboard, and switch off Sticky keys, Filter keys and Toggle keys. Filter keys is what makes keys need a long press.

  3. 3

    Clean under the keys

    Switch off, turn the laptop upside down, and use compressed air along the rows. Crumbs and dust cause a large share of dead keys.

  4. 4

    Test with an external keyboard

    If a plug-in keyboard works perfectly, the built-in one has failed, which confirms it is a hardware repair.

  5. 5

    Reinstall the keyboard driver

    In Device Manager expand Keyboards, uninstall the device, then restart. Windows reinstalls it automatically.

If none of that worked

Never pour liquid on a keyboard to clean it. If something was spilled, switch off immediately, turn the laptop face down, and have it opened and dried professionally.
