My 3000 c200 has a problem with some keys. pgdn, pgup (also fn Home and fn End) are not working. Arrows are ok, and fn with other keys is also ok (like volume control, brightness, ect). Also the windows key and application key are not working. I think it is not a hardware problem but a software one. Seems like a setup was changed and those keys are blocked.
Anybody knows what could it be happening here ? Any suggestions ?
