Laptop video only with external monitor

[MeiaNoite]

Heyia!

Guys i am getting a weird freaking problem here.

I have a Dell Inspiron 6000.

The problem i am having is that my dell will not show on its monitor image what so ever! But not alwayssssss...

1. Turn dell on, image just fine, can access bios and so...
2. Booting, windows loading screen fine too, no problem at all.
3. When windows load up, supposed to show desktop, done... screen gets black.

Facts?

- It will show full resolution 1920*1200 (or something like it) in safe mode.
- Will show image under F8 - VGA Mode
- Will show image just fine instaling XP.
- Will show image fine fine fine untill i install Video`s driver.

After install the video driver, which i tried like 3 different verions, windows does not show any image anymore.
External monitor works fine!
Fn key + F8 which is for switch between screen, only make my exernal monitor blinks... but laptop still no image.
Tried bios reset and load default valeus.
Tried Windows XP SP2 and SP3, clean install from zero.

Really sounds like a software problem but i am already starting to think that some kind of hardware is broken. WTH!

Under video propeties, where it shows "Monitor" "Panel" "TV", monitor is on (of course, i am using one to type here...) Panel and TV show "not connected". As well Panel and TV buttons are disabled, so i cant turn it on.

Any tips?? I dont know what else to do.
Thanks !!!

Thanks a lot for the quick reply! Oh well, it does look like some hardware failure in the mobo showing up with some graphics driver feature. Anyhow, the good thing is that this is a corporate laptop, so once I am back from holidays I'll give it to the IT service of my company and let's see what they say. It was fun to try but heck! I'll post here the update then... .

Thank you again!

No luck finding the exact cause. The guys just replaced the full laptop (changed my drive to new laptop). I guess that proves was hardware . Oh well...
