Whenever I turn on the computer it gives me a blue screen with the message "Enter Power-on Password"

I've tried resetting the cmos to no success,  and I can't find any motherboard jumper pins.

Hi:

See the service manual at the link below, chapter 5, page 154 for how to clear the P/W...

The manual indicates the password jumper is blue so it can be easily identified.

On all my HP business desktop PC's, the clear P/W jumper is green, so look for either color.
