How to wake Dell All in One, Win 7, from sleep mode


In Windows 7, there is a bug, if you put the PC in sleep mode when the system is running on batteries then it may still drain out the batteries and you cannot wake it up. In this case, you need to connect the AC power and reboot the PC. If you put the Pc to slepp when the AC power was connected. Then there are no issues and just by pressing the enter key it should come out of sleep mode. Sometimes - depending upon settings - you may need to press the Power button the PC to wake it up from sleep mode.
If you have already tried all this, then please go to the Power settings in Control panel and check all the setups that exist. You may need to change some of them.
