Does someone know how to reach a CMOS battery on HP ZD7000 laptop or is there any jumpers to reset the BIOS? Somehow the screen stoped showing anything. I can hear the Windows start up sound but the screen is black at all time. Looks like windows is sending video signal to other display. I tried everything I know with no luck and a last thing remains is BIOS reset. Thank you.

Looking in the user's manual? That's always the FIRST place people should check when trying to locate a component.

You must remove the optical drive, the keyboard cover, the keyboard, the top cover, the display assembly and the system board, all of which require knowledge of disassembling/reassembling a laptop.

The battery is on the bottom of the system board.

I could probably do that if I had step by step guide or instruction how to disassemble a laptop.

The step-by-step procedures for taking it apart and putting it all back together again are in the manual.

Hey,

Probably resetting the BIOS is what you mgith want to do.. but before that try this

When your windows starts try pressing F8 key repeatedly, after you restart your laptop (important to press and release instead of keeping it pressed once)

If you can get to this screen, try choosing the option which says something like:
"Enable VGA mode"

This would be the simplest thing to do, since the monitor should display the output on the default monitor(laptop screen).

If this doesn't work, then HP guide would be your best bet (look at ThumbsUp2's reply)

Best of luck

Ash
