I faced this problem few times in power saving mode. Earlier I was not sure when I encounter this problem. But today I got the problem exactly when I encounter this problem.
When power goes off and my window 7 (win7) goes to power saving mode due to that and I close/shutdown/sleep mode that in no power situation and when I come back when power is available then I get full brightness. This has strained my eyes many times. As in laptop (Dell Studio), even after full brightness/contrast, the screen does not become fully white. I can read the text. But this affect the eyes and easy not to notice this change for long time.
Do I have any solution for this?
I tried to search for the place on Microsoft website where I can write bug report but Microsoft is not accepting the bug for Win 7.
