Power management keys, in fact, are three keys on computer keyboards which control the computer's power management status. They are the Power key, the Sleep key, and the Wake key:
First, the Power key is used both to power on and to power off the computer.
Second, the Sleep key is applied to put the computer to sleep, when it uses significantly lower power than when it is active, but can be woken quickly.
Third, the Wake key wakes the system from standby.
The power saving modes and the transition between them is implemented using ACPI.
On computers running Windows Vista, the Windows key can act as a power management key, and turns on the computer when pressed.
The placement of the three power management keys on a computer keyboard varies basing on the keyboard's model.
Ideally, these keys ought to be placed far enough from the rest of the keys, since the consequences of accidentally pressing one of them while using the computer can range from being annoying to causing data loss. For example, if the user has edited a file, but not saved it yet, on some applications shutting down the system could easily lose all the changes. While the results of wrongly pressing the Sleep key aren't as extreme, it may cause problems in real-time games or any application which bases on a network connection.
