Solve : can not be waken up from sleep mode?

1.	Solve : can not be waken up from sleep mode?
Answer» My computer is just bought not long ago, before sleep function WOKS quite good, but now it can not be wakened up from sleep mode, my computer is windows 7, home premiumI have seen UPDATES BREAK this feature before. Have you backed up your important data and then tried reverting back to oldest restore point or even restoring your system from system restore image which sets it back up to factory build defaults? I am guessing that setting it back up to factory build defaults by performing a system restore from image will correct for this. Test after this is performed and offline so it DOESNT automatically take updates. If all is well, then perform all microsoft updates and then test again. If it then breaks the sleep mode, then its an UPDATE that is causing this.many thanks, this problem has been solved, i update the computer, now it works quite good~
