You need to replace the back light in your screen. Depending on the laptop, the back l light can be relatively cheap. It is usually the repair that costs the money. If you decide that you want to replace the back light yourself, you can find a few tutorials just by searching google.

It sounds like you need a new ballast unit for your screen. It cannot be a processor problem as the laptop works OK on another screen. The ballast unit is beneath the screen itself. Check ebay for a keen priced ballast unit or complete screen. Hope that helps.

The touchpad is installed on HP notebook PCs.
You can "tap" and "double tap" your touchpad with your finger, and interact with the operating system in exactly the same way as clicking and double clicking on your mouse.
When using touchpad on your notebook PC, the cursor may jump, flicker, or double-click by itself.
Follow the recommendations in that HP document, or "disable" the TouchPad, if you don't like what it does.
Hello If you can faintly see the screen I would guess the back lights are like you said....not working. Can you hook up a external monitor or TV so you can still use it and get your files in order. or until you choose to get it fixed. I would get a couple of estimates first I also found this video if you want to replace the back light inverter yourself. http://www.youtube.com/watch?v=UT2GFVem_9U&feature=PlayList&p=70B03BCB27E35519&playnext=1&playnext_from=PL&index=16
If it seems like you're accessing the hard drive (drive light comes on, flickers intermittently, then goes off, it's a good chance your screen is bad.
First thing to do is plug in an external monitor and start up the laptop. If it comes up with windows, you know it's the screen.
To find out if it's the backlight, or the lcd, toggle the monitor function and shine a flashlight on a slight angle to the screen. If you can faintly see what was displayed on the external monitor, then the backlight inverter is probably bad.
If the external monitor didn't come up, you're probably looking at a motherboard.
The good thing is that all of those are covered for one year under Compaq's warranty, on a new machine.
If you are able to use the external monitor, back up your data, because HP/Compaq usually reformat the harddrive. Additionally, if you've added memory, pull the cards. They want it sent back the way it came from the factory.
