ATI Radeon xpress 1100
When I left the laptop for about 10 minutes, the screen turn to blank. I tried some options in screen saver and power management to disable that function but no success. Even when I play DVDrip movies, the screen turns to blank after some minutes too. That makes me a little uncomfortable ( I must move the mouse every 10 minutes when watching the movies).
Please help me to solve this problem.
