I have a laptop AH530/GFX (a series). Sometimes everything works fine, but there are times when I try to open it, and the screen is just black, it shows nothing. The fan and the lights bellow the keyboard work properly, so I can suppose it's not a matter of the battery or the power. Any solutions?

My computer turns on but nothing displays on monitor. HELP?

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.

Hi:
I am sorry to tell you that this series of HP laptops has a known problem with the video chip on the motherboard. There are thousands of complaints to HP about the DV9000 seriies laptop, and yours has the same sympoms that others have reported. HP extended the warranty on some, but most people lost their shirts. There are a few people who have had mixed success in repairing the motherboards, but often they have to get replaced. If you did a google search on yor laptop problem, you will find lots of info.
The bottom line is that your laptop is expensive to fix, and it is a known problem!
