Interesting Display issue

Super_Nova · 06-07-2007, 09:56 PM

I have a customer who brought us her Dell laptop to work on. The issue is as soon as windows gets to the log on screen it switches to the external display and will not display on its own LCD. Even if there is no monitor attached. It works fine on a PE disk or Live Linux disk. It works fine if I don't load the driver. But as soon as I load the driver it's as if it's defaulting to the external display. I even formatted and reinstalled windows, but as soon as I loaded the driver it defaulted to the external display.

Maybe there is a setting for that in the Bios or something. Can you use an external monitor to set it back to its own internal LCD?

Have you tried reloading the drivers or uninstalling them and using the basic "Standard PCI" drivers?

Here's what I've done so far. I've tried several different drivers. I tried the one off the Dell website as well as the ATI DNA driver. I've called Dell and changed out the system board and video card. I've reformated windows twice. Still, once the driver initializes it automatically switches the internal LCD off and switches to the external display and it's as if the internal LCD display isn't even there in any of the settings. So far we have a new registry, new drivers, new hardware but yet we have the same issue. The LCD works fine while the system is posting. It works fine in Safe mode. It works fine with the driver uninstalled. But once the driver starts up it turns off the built in LCD and switches to the external display.
