Laptop screen doesn't work in vista 64x

Hi i would like some help!!!!!

my laptop screen stops working when login to windows (when in normal boot mode). So when i boot in safe mode it does work!

also i don't know when it stop working in vista since i normally always work with my tv, you see and rarely switch back to my laptop screen.

so what i have tried so far:
reinstalled the VGA drivers
checked with search & destroy, ad-aware and comodo virus scanner.
updated everything
let windows repair it-self
did a system restore to a earlier date but the only one i had was from 4 days before i noticed the problem(so not very useful )
cleaned out my start up programs
also did a Cclean of my browsers and reg
also uninstalled some programs i didn't use or didn't know why they were on it anyway .

specs:
intel core 2 duo t7500
intel 965m chip
4gb ram
vista 64x ultimate
if you want more specs ask...

so can some help me out please, i have ran out off idea's what to do about it....

The next time you have it rigged to your TV, try hitting fn+f5 and see if it will switch back to the laptop screen. Seems as if it is stuck on external display.

problem solved

we just had a cutoff of power so my laptop had to verify stuff and i plugged in my battery. and guess what, when finally booted in windows i saw that the screen flickered once for checking all the monitors. and there it was in my screen settings! laptop screen returned.

i don't know what was wrong or if the battery had any effect in this play.

but problem solved!!!!!!
