Raaj - did you ever get a response? I am having the same issue. Although my monitor will flicker and then go out.
I have a old T20 which has been quite good to me so far. Oflate when I start up my pc the contrast is gone to almost 5%. If I look closely I can see the screen. I have to hold the 'Esc' button for a minute or so and then the brightness would come up within 5 minutes. I tried updating the drivers but didnt help. I am sure some of you would have come across this problem. Please help. I dont wanna buy a new laptop just because of this reason.
Regards and Thanks,
