asked on Toshiba c8556-s5196 keyboard suddenly doesn't work
A Toshiba c8556-s5196 running Windows 7 was working well and suddenly the keyboard doesn't work on the built in keyboard or an attached USB keyboard. It works minimally in that the user can type in the password to get in. It also works when f8 is pressed to get the machine into safe mode.
I tried running it without the battery and the problem still was there so it doesn't seem to be the battery ACPI setting.
It doesn't seem to be a hardware problem because the keyboard works very minimally and the USB keyboard also doesn't work. The synaptics pad works.
What could be the problem?

It doesn't work in safe mode.
I'll do a malware scan and see what comes up.

Removed the laptop keyboard and usb keyboard still didn't work.
Malwarebytes found one item in quick scan and removing it didn't help. Doing a malwarebytes full machine scan.
Will try last known good configuration next.
The machine's last updates were weeks ago and it was working well after those updates.

The advice of the experts led me down the path to finding the problem. The solution that accounts for all 3 keyboards not working is the ease of access filter setting set when it shouldn't have been.
i would uninstall the latest updates - they are often the cause of these problems
or do a system restore - as suggested
