Thread: Keyboard problem

My computer keyboard keys 1, q, a, z are not working please help me to release them.

Probably a bad keyboard what happens when you try a different one?

It doesn't seem likely a particular key sequence would cause that. Most keyboards have Mylar sheets with conductive circuit lines drawn on them connecting the keys. If one of the circuit lines breaks it can affect several keys, usually ones close together. The fact that your 1, Q, A, Z don't work the left-most column would indicate that's the problem.
