No information is shown on the laptop's LCD during boot or with Windows 7 running. If I hook up an external display all information is shown on the external display. I've tried switching display's with fn+f5 several times with no luck.

Now the the catch. If I boot into Ubuntu then the laptop's LCD display will work only after Ubuntu boots and the X server has initialized. Still no boot process display.

I've reset the BIOS (unhooked the battery on the motherboard etc and set them to default factory). I've even flashed the BIOS to A17

I'm assuming since Ubuntu works, its by-passing the various firmwares and managing the system itself.

Ideas?
