I am working with a client who is in a group home for mentally challenged and/or disabled adults. He has the toshiba C655D sattelite laptop. I was able to fix all the issues except I cannot figure out how to get the keyboard to work. I tried the language and region settings, those are all correct. I tried to use the on screen keyboard except the keyboard doesnt work so I was not even able to that! The arrows, touchpad and mouse all work. The function settings (of those I tried) also seem to work. Can somebody please help me?
