HP, compaq presario laptop, R 4000 powers on, but has blank screen.
Posted on 2008-10-19
My problem began when I didn't know the power-on password for a compaq presario R4000 laptop which I had bought at our local swapmeet. I figured that if I just removed the laptop's internal battery it might reset or let me bypass the password. But, now nothing at all appears on the screen when the computer is turned on. The keyboard has no indicator lights on anymore, and when I press the F1 or F10 or other keys, nothing happens. The dvd drive does sound as if it's working, but still nothing appears on the display screen, so I can't be sure. What might the problem be here? And are there any solutions, besides buying another laptop?! Thank you for your help.
