As the headline says, a large chunk of the keyboard suddenly stopped working. Ctrl, Alt, Alt Gr, PgDn, PgUp, arrow keys, and Esc, at least.
I've tried reboot, hard/forced reboot, and clean reboot. There is no keyboard driver or Launchpad utility available on Acer's website.
Model: Acer Aspire E3-112
Windows 10 64-bit
What do I do? I've had trouble with the touchpad before, which was resolved following a Windows update. I haven't found anything here or through Google, but maybe several users are experiencing this problem right now and it is being fixed as we speak?
