• Power management settings are user specific. This could, therefore, have roaming profile implications.
• Power management settings are held in the registry. These registry settings live in both the Machine and User areas of the registry.
? HKLM\Software\Microsoft\Windows\CurrentVersion\Controls Folder\PowerCfg
? HKLM\System\CurrentControlSet\Control\Session Manager\Power
? HKCU\Control Panel\PowerCfg
• In order to configure power management the user context needs to have permissions to the appropriate registry keys.

Microsoft has supplied a command line utility, powercfg.exe, to manage power schemes. Most online documentation illustrates the use o powercfg.exe at logon to manage power management in the enterprise. The use of powercfg.exe is described in Microsoft’s KB324347.

It is possible to modify the registry directly. However, in order to configure power management fully, after one has modified the registry one needs to inform windows that something in its environment has changed. This can be done using Win32 API calls.

Microsoft has provided a power management API. This gives access to setting which are not available via the control panel.

Muralisai25 - Did you get this to work using powercfg or another tool? Please share - I need to do the same...

in addition, the motherboard must support wake on lan feature, which i'm sure, you know, it's obvious.

Hi Barny,
Yes i know and it does support the wake on lan feature, else i would not bother to make this work

Mark07,
yes i have simple batch script that uses the powercfg tool to change this setting and works like a charm in windows "XP" only. Unfortunatly i have about 4000 PC's running Windows 2000 and like 500 with XP. I only wish MS or someone has a simple solution or a workable solution for this.
Thank you all. Keep me posted if you guys find anything
Cheers!
