Step 1: Check the USB connection

USB cable and port

Unplug the USB cable and plug it back in. Try a different USB port, preferably one directly on the motherboard.

Avoid USB hubs

Connect the keyboard directly instead of through a USB hub.

Wireless keyboard

Check the USB receiver and replace the batteries. Make sure there are no obstacles between the keyboard and the receiver.

Step 2: Reinstall the drivers

Uninstall and reinstall the driver

  1. Right-click Start > "Device Manager"
  2. Expand "Keyboards"
  3. Right-click your keyboard
  4. Select "Uninstall device"
  5. Restart your computer

Update the driver

  1. Open Device Manager
  2. Right-click your keyboard
  3. Select "Update driver"
  4. Choose "Search automatically"

Step 3: Turn off Filter Keys

Filter Keys can be turned on by accident by pressing Shift 5 times.

Turning off Filter Keys

  1. Open Settings (using your mouse)
  2. Go to "Accessibility" > "Keyboard"
  3. Make sure "Filter Keys" is off
  4. Also turn off the keyboard shortcut

Also check "Sticky Keys" and "Toggle Keys".

Step 4: Use the on-screen keyboard

A temporary workaround while you fix the problem:

  • From the sign-in screen: click the accessibility icon
  • From Settings: Accessibility > Keyboard > On-screen keyboard
  • Search for "osk" in the search bar

Step 5: Test the hardware

Test on another computer

If the keyboard doesn't work there either, it is probably defective.

Test with another keyboard

If that one does work, your original keyboard is defective.

BIOS test

If your keyboard works in the BIOS but not in Windows, the problem is software-related.

Additional solutions

  • Run Windows Update: Can fix keyboard problems
  • System Restore: Roll back to an earlier point
  • Clean the keyboard: Dirt can block keys

Frequently asked questions

Why does my keyboard work in the BIOS but not in Windows?

This points to a software problem: corrupted drivers, conflicting software, or Filter Keys. Try reinstalling the driver.

My wireless keyboard stopped working after I replaced the batteries.

You may need to pair the keyboard again. Find the connect button on the keyboard and the receiver and press and hold both.

Some keys work, but others don't.

This often indicates physical damage or dirt. Try cleaning the keyboard thoroughly. On mechanical keyboards you can sometimes replace individual switches.
