Keyboard not working at BIOS

By twelch ·
I have a HP Pavilion a1730n, hooked up the computer and powered it on, completes post fine and shows the BIOS screen, the keyboard does not respond to any key presses. The hard drive is wiped so with XP CD in and when "Press any key to boot from cd" comes up to boot windows the key presses do nothing.

We have tried several USB and PS/2 Keyboards with no luck. Also tried removing the CMOS battery with no luck. Also tried new ram with no luck. Any help would be much appreciated!

If you have removed the BIOS Battery you need to reset the BIOS

And to do this you need a PS2 Keyboard not a USB Keyboard. When the HP Logo appears on the screen press the Delete Key and hold it down till the BIOS Screen appears Look at the keyboard and see if a Green LED is illuminated as it is possible that the PS2 Port is not working here if that is the case you'll need to look at the M'Board manual to see if there are any Jumpers to remove the Power from the PS2 Port and reset this if there is. If there is no Jumper you and the keyboard is not having any effect you need a New M'Board.

If the keyboard is working here you need to set the Date & Time and set the BIOS to Performance defaults then set the Boot Order to Optical Drive before HD and then save the changes when you exit BIOS. Follow the prompts and install Windows with the PS2 Keyboard attached.
