Fix: USB keyboard not working
A USB keyboard usually stops working because of a loose cable, bad USB port, stuck driver, disabled device, or the keyboard itself failing.
Quick answer
Unplug the keyboard, try another USB port, restart the computer, then test the keyboard on another device if possible.
Important warning
If the keyboard got wet, unplug it immediately and do not keep testing it while powered.
Try this
- 1 Unplug the keyboard and plug it back in.
- 2 Try another USB port on the computer.
- 3 Avoid USB hubs while testing. Plug directly into the computer.
- 4 Restart the computer.
- 5 Check whether the keyboard lights turn on.
- 6 Try the keyboard on another computer if available.
- 7 If another keyboard works in the same port, the original keyboard may be faulty.
