I have Windows Vista basic, i used to close my lid or press the power button and the laptop would sleep but now when i press the button or close the lid, the computer stays running and when i open the lid, the screen was like it was before i closed it. My problem is the fact that it won't sleep or hibernate. I click power manager and clicked " what happen when i close lid" and put all settings to sleep.

Help is appreciated .
