90% of Toshiba keyboard won't work

[BackSpace303]

I have a Toshiba laptop (windows 8) and my keyboard has been acting up lately. Only the top row of keys work. (Screen brightness, F keys, delete etc) I've tried looking at the sticky keys and checking the driver but nothing worked. The weird thing is that my keyboard DOES work when I have to type in my password. Also, I've had this problem before and it got fixed somehow, but I don't know how.

I can't find anyone else with the same problem, and nothing seems to work. Please help!

Hi,

Please do try these troubleshooting steps that may help.
- First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If the keyboard will still not work, proceed with uninstalling/reinstalling the keyboard driver.
- Go to Device Manager and uninstall the keyboard driver, reboot the laptop once uninstalled and it should reinstall the driver automatically upon reboot.
- If this will still not work, connect an external USB keyboard and test if it will work or not.
- If the external keyboard will work just fine that could mean that the problem is the built in keyboard.
- I would suggest opening the laptop and check the ribbon cable that connects the keyboard to the motherboard.
- Unplug the ribbon cable then plug it back in and test it again.
- If all these will not work then last option would be to replace the keyboard.
