电脑显示器不能自动关屏 xialele2012-01-04 03:25:05

I have a Samsung Intel Core i3 lap top. The problem is that the screen can not turn off automaticlly according to the power plan. The screen stays on throught the night if I forgot to close the lid. Now I see a few dead pixels. Any one know what is the problem?

 

Thanks!
