No Screen on Notebook Compaq nC8000

Hi

My laptop has some keys down on the right side showing lights on it and some laptops has them up the top of the keyboard i think

if you can see them press FN and the light up or down key to brighten the screen

If you cant find the keys check out the manual for your laptop if you have it

Hi, sounds like what is known as the blue screen of death. You can try reseting your operating system to an earlier time, before the problem began, by pressing the ESC or Del key during bootup, this will give you the option to boot into safe mode, from where you can attempt the reset. Or you can insert the CD that came with your compaq and perform a system restore. Both of these options will not remove any saved data.

try press f12 and hold down on restart of computer you should have options

There are many factors which might be causing this problem...Maybe the laptop battery is not charging properly of else there's a failure in your O/S or even a faulty motherboard.

Thanx for using fixya.

Unfortunately, sounds like the LCD backlight or backlight power board is bad. If there is any warranty, lucky you. Otherwise you need replacement parts. The output voltage on the powerboard needs to be checked to determine what needs to be replaced. Backlight Approx $20, powerboard Approx $65. This is the cost for parts alone if you are into electronics, otherwise a repair shop would end up charging you $200 - $300. There is a slight possibility that it is only a loose connection (cold solder joint or loose cable), but the laptop would still need to be opened, Lots of luck

Sounds like the battery or possibly the charging circits themselves are the problem. Can you try turning on the laptop with just the power cord in and no battery?

check your keyboard connection (unplug and plug again). If not works try another of same type.
