When the keyboard is being used, keys are unresponsive

In many cases the keyboard itself just needs to be rebooted. To check for this problem, click the ‘caps lock’ button and see if the light turns on. If it does not turn on, restart the computer and try again.

A common cause for keys to be unresponsive is if the keyboard itself is dirty or dusty. Use a laptop cleaning kit or a dry toothbrush to gently clean around the individual keys and keyboard. Try using the keys again.

If there are only a few keys on the keyboard that are unresponsive, you can replace them individually. A key needs to be replaced if it is physically damaged (cracked, water damaged, etc.). Replace keys using this guide.

If the keyboard itself is unresponsive, you may need to replace the whole thing. In order to resolve this problem, you need to purchase the keyboard your computer requires online. Replace the keyboard using this guide.

If the fan doesn’t turn, there may be an issue with the fan itself. To fix this problem, replace the fan using this guide.
