LCD backlight issues on laptop
Posted: Wed Mar 21, 2007 11:57 pm
I have a Compaq V2000 series laptop and it has a problem. The backlight doesn't work if I turn the laptop on without having a power cord connected.
If I turn it on without the cord, then connect the cord and press and release the backlight switch (the one that turns off the backlight when the lid is closed) then the backlight comes on and stays.
If I just press and release the switch without attaching the power cord, then the light comes on for a moment and goes off again.
The screen had some dead pixels so I sent it to HP to get the screen replaced under warranty and the issue appeared after I received it.
I've sent the laptop to HP again to get this issue fixed, but they didn't do anything and sent it back to me with a paper saying that they didn't find the issue.
I'm 100% certain its a software issue, just not sure where to look.
EDIT: I've formatted the HDD and reinstalled WinXP Pro SP2 and the issue is still there. I think its some sort of an inherent driver fuckup.
