HP ProBook 4730s Keyboard Not Working - How to Fix It

I was just working on an HP ProBook 4730s and the keyboard stopped working. None of the keys worked. I figured maybe I had hit the Alt key and some other key and inadvertantly changed a setting.

I went to another computer and looked up keyboard settings and fixing a broken keyboard, keyboard not functioning, etc..

I don't know what caused the problem, but it was really simple to fix. If this happens to you, shut off the computer, unplug the AC cord and remove the battery for a couple of minutes. I don't know why, but it worked. I am typing again.


  1. I've had the same thing happen with my three week old ProBook 4430s. I think it is caused by static electricity buildup, because I've also shut off my ProBook about 10 times when I sit down at my desk and touch it and I can feel the shock.

  2. Thank you so much, i was asked to fix this problem on ProBook 4430s and as i dont windows that much i had no idea what was the problem. But i took the battery out put it back in and turned the computer on and it was fine, just like you said it worked no problem.

  3. You have saved me :-) . Thanks!!!!!!!

  4. My hp probook 4520s keyboard not working I remove the battery n others output devices for about 10minute it's still not working somebody help pla
