=== Configure Power Management with powercfg in Windows XP ===
Since Windows XP SP2 powecfg.exe can be used to manage Power schemes. This can be used as a GreenIT tool to manage the power consumption of the computers. This can be used in combination with [[PowerOff]] to shutdown computers at night if the hibernate mode is not used.
For WindowsXP PowerCfg options see : http://ss64.com/nt/powercfg-xp.html
