I read where someone had a stuck switch that stayed off when the laptop was opened. Simply remove the keyboard and spray air into the fan until all dust is gone. It sounds as though the backlight may have been damaged when it fell. Any suggestions for next step? Thanks for the directions.

Have you tried headphones? Didn’t find what you were looking for? I saw the pictures of how to take apart the laptop, I removed the screw for the dvd rw and it just wont slide out of the computer, not sure if have to take apart the whole assembly to remove the dvd drive, i unscrewed it, but still it wont come out.


Replace the wireless card.

Sometimes the screen goes completely black I can see the backlight is functional but no information on the screen or sometimes mostly horizontal lines. Is this a mechanical problem? Is there a board or chip or something that I can buy and replace? I have a small problem i need some help on. But laptops f70 doesnt. Worked fine for a Compaq V with the popular graphics chip problem. Unlock the socket there is a screw.

I hope those guys checked the AC adapter.

Thankyou for your response. Replaced screen, still same problem. I would check the AC adapter. The LCD cable connector is shown in the Step When I do get it to come on, it will either stay on the black screen that says COMPAC, or it will go to the windows repair up and stay there for a really long time scanning.
