Hi,
Here are some details on my computer:
Toshiba P100 SD 802F
Display LCD : 17 inch 1440x900
Video adapter : Geforce 7900 GS driver 8.4.0.0 (original driver)
BIOS : 3.8 (latest driver)
All other driver are original
Windows XP media center with SP2

How it start :
I has running on battery because was on the train (level 75% so might not be the problem)
I install software MagicTune version 9.1.0.429 with is coming from samsung when buying their external LCD display 226BW.
Install complete and ask to reboot
Just before reboot, a message error say that MagicTune could not install correctly.
Plug computer because arrive at home
Reboot computer and my laptop LCD is black but I can see it is on because there is blur when I touch it and the black is not a "normal" black
I plug my external LCD display and it automatiquelly show my BIOS password screen on it but not on my laptop screen.
I can boot normally and do everything with my external screen but it is annoying not to have my laptop LCD working.

In the menu configuration (Display properties setting), Windows do not detect my laptop screen.

What I did after (with no particular order)
I uninstall MagicTune
I updated my BIOS from ver 2.0 to 3.8 (latest version)
Desinstall nvidia driver, reboot and reinstall original driver
Try key Fn + F5 and no effect except external screen goes black and come back (This is my key to stich between screen configuration)
Check my BIOS and put setting dual screen on boot
I check with nvidia tool for clone screen and other setting (no help)
I check with display property, only detect the external screen (no help)
I run Mc Afee, AD Aware (no help)
Start in safe mode
Go back to earlier windows restore point
Complete format of harddrive and new windows installation

Thanks in advance for your help
If you have any question don’t hesitate to ask
