All keys on keyboard do not work after upgrade, touchpad still works, Is there a phone number?I cab’t chat because the keyboard is frozen. However, I can use my phone to communicate

laptop keyboard and touchpad not working

Problem: computer starts up normally and goes to the password log-in screen, but nothing happens when I try to enter the password. The computer doesn't appear to see any keystrokes.
Solutions tried:

1. rebooted
2. removed and replaced main battery
3. attached USB keyboard
4. hit Enter key on startup: successful in opening the Advance Options menu, but am unable to take any of the actions because all require that I enter the laptop password
5. looked for an onscreen keyboard, but there isn't one because this isn't a touch screen computer

Why I think this is a Windows issue:

1. the computer recognizes when I hit the Enter key on startup
2. the USB keyboard doesn’t work
3. the keyboard touchpad doesn’t work, but the attached USB mouse DOES work

 

Keyboard Volume Keys not working while in-game

I happen to have used the Tt Challenger Pro keyboard in the past, and the volume keys worked flawlessly in every game, so it's indeed a weird problem. I would suggest the same thing sneekypeet suggested, using the keyboard software and assign this function to a hotkey, but you said that didn't work either, so yeah...

 

The f1 key and the f2 key do not work
