I have a Toshiba Satellite A300-23J and have been running Windows 8 and later windows 8.1 for some time now. Last night my keyboard stopped working for no possible reason. When computer starts up (I think it's called during POST ?) my keyboard works. I can easily enter bios and navigate into it. There is no option to enable or disable keyboard on bios.
Things done so far:
- Checked Device Manager (not in Safe mode) everything looks OK (no Exclamation marks or red Xs). Tried uninstalling and re-installing the keyboard from there still nothing.
EDIT If it helps the mousepad also stopped working about a week ago but I had an external mouse in handy so I did not really bother with it (the external wireless mouse works perfectly, even custom button commands using x-mouse button). There seems to be a light on the mousepad (a horizontal line light at the bottom of the mousepad before the mouse buttons) which turns on, but no part of the mousepad is working.
