Question : Problem: Random Keys not working

I have a laptop which has a problem with the following keys:

m, \, caps lock, windows key, left arrow


I changed the keyboard and still have the same issues.

At this stage I thought it was a keyboard controller (hardware) issue, however when i plug in a usb keyboard i have a similar but varied issue.

With the USB keyboard the numbers 1,2,3,4,7,8,9,0 don't work as well as a few other keys.


Does anyone have any idea why this is and if it can be fixed?
