When you put a computer to sleep is a power-saving state. Sleep saves all open documents and programs, and allows the computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer to sleep is like pausing a DVD player: the computer immediately stops what it’s doing and is ready to start again when you want to resume working.When you put a vista computer to sleep, does it allow processes that were running (such as a norton virus scan) to keep running? Or does it pause them?
Also, the same with the lock button, does it let programs run? or does it pause them?
