Laptop screen way too dark

By maryunger3 ·
I have a Presario r3000, pentium 4,512 mb ram, 40g. HD. My screen looks all black unless you have a bright inches from it, I put a desktop monitor on it it works untill it hangs at the win XP logo screen for about 3-4 minutes and then the monitor light goes orange and then the monitor shuts off but the computer stays on.

Those units have a backlight behind the display
element. It'll run about $100 to repair.

The Back Light is part of the answer here as that is why the screen is so dark but it also sounds as if you have some other problem as well if you can not get Windows to boot.

Try this and see what if anything happens download The Ultimate Boot CD from


Burn it to a CD and boot from that with the external monitor connected and rum some diagnostics to see if you have a hardware or software problem. The first test would be a HDD Test to see if the HDD is still working properly but you can then do some CPU or M'Board testing and make sure that the unit is working correctly.

If the external Monitor still goes out you need to look at replacing the M'Board and that isn't going to be a easy option. Unless it's still UG in which case I would RMA it immediately to get it fixed but if you don't have your Data backed up you'll need to do that first.

oh dear, it sounds like the video card went in the compaq. they have step by step instructions on how to replace it at the compaq website. it is not hard, just tedious and well, i always find that stuff scary because it is usually the bosses' laptop...you'll need special torx bits, long and short. i got a nifty compaq screwdriver with all the bits for $40 at www.impactcomputers.com. they have parts there also but i would not buy their refurb stuff, too much work to replace the thing...
you could also get a docking station for it to allow you to put in a new video card.
