Check for hardware damages

Before you start with the following procedures, take a look at your keyboard. If your keyboard is damaged, physically, it may not function as expected. This has nothing to do with your keyboard driver.

You can claim a warranty from the buyer or manufacturer to repair your keyboard. If your keyboard is mechanical or semi-mechanical, you can buy new keycaps for your switches.

Keyboards with removable/interchangeable keycaps have to be cleaned regularly after you remove the keys. If all of the above physical fixes do not fix your keyboard, do as the following procedures instruct.

If this doesn’t work for you, it is time to purchase a new keyboard. Check for keyboard compatibility before you buy it.

Take a look at the keyboard cables

The cable used to connect your keyboard with the computer may be twisted, damaged, or loosely connected. This can happen to the USB pin too, causing your keyboard to not be detected by the computer.

If your cable is damaged, make sure to cover the damage with an insulating material as direct exposure to the ruptured cable can cause shocks. You can also change the cable with the help of tech support.
