Some keys on keyboard don't work

[foti]

My laptop is a 3 year old HP Probook 4520s. For about one year the "Fn" key hasn't been working and just yesterday the keys "Q A Z CAPS LOCK TAB 1 ESC" stopped working for no reason. I'v tried re-installing the driver but still nothing. any idea how to fix this?

It sounds to me like its the keyboard itself. Depending on how old the computer is; certain letters could just be wearing out which means the keyboard most likely needs replacement.

I tend to agree with Matt keyboard or rather the key pads are made in different formats but are usually two small pads of rubberized material that will conduct electricity. A lot of use will eventually wear these to the point where they will not conduct or they have been damaged by direct violence (intended or not) or something being spilt on them.

Anyway this is what you want if you go the path of replacing it - as long as you can get one.
