So, I read some of the related posts on here but couldn't really find the solution. I have a ps/2 port but my ps/2 keyboard doesn't work on it anymore. Maybe it's broken or something. So, I got a new keyboard. A USB Keyboard and it worked just fine. I could enter BIOS with no problem and even formatted and re-installed windows on my computer so many times.

But, a few days ago, I tried accessing my BIOS setup and it wouldn't let my keyboard work. I even checked it by trying to boot with a CD, but it wouldn't accept my keyboard press even though all the lights on the keyboard were on. I tried resetting the BIOS by switching off and on the switch at the back of my CPU, but it doesn't work. I keep hearing those clicks when I boot my pc. I read somewhere about Click BIOS but couldn't find one compatible with Intel.

  • Does the USB keyboard work within windows ? – thilina R Apr 17 '15 at 13:51
  • To reset the BIOS, you can remove the BIOS battery and wait for a few seconds and put it back in. Not sure if there will be a switch to do that – thilina R Apr 17 '15 at 13:53

    @slayernoah pretty big approach for this problem. I would definitely not reset the BIOS to defaults just because the keyboard is not working. – LPChip Apr 17 '15 at 14:33
  • @slayernoah yes, it does – Ashfaaq Apr 17 '15 at 15:55
  • @LPChip i have to reinstall windows. So i need the keyboard to work so i can boot from dvd – Ashfaaq Apr 17 '15 at 15:55

USB keyboards require a small time before they are properly initialized. Just because the backlid works doesn't mean the keyboard is ready to be used. Usually if the numlock can be turned on and off, you know the keyboard is ready to be used.

The BIOS will initialize all your USB hardware in order, and once your keyboard has been initialized it will start to work.

You should unplug all your USB devices and only plugin your USB keyboard, reboot the computer (2 times or more if necessary) until your keyboard is able to work and you can access the BIOS. If it keeps failing, plug it into a different USB port.
