Thread: Keyboard problem

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

Probably a bad device what happens when you try a dissimilar one?

It doesn't seem likely a particular key sequence would cause that. Most devices have Mylar sheets with conductive circuit lines drawn on them associating the keys. If one of the circuit lines breaks it can affect various 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.
