Hi, We are trying to reduce the amount of electricity that our PC's use on a day to day basis. At the moment, the only powersaving features that we have enabled is that the screens go on standby after 30 minutes. Ideally, we would like the PC to go into hibernation if left idle for 2 hours, but I have a few questions about the hibernation mode. We have various software updates pushed out to the PC's overnight, if the PC is in hibernation, would it automatically wake and accept the updates as normal? Would the PC wake on a ping command? Are there any other powersaving features that are available in Windows XP apart from those listed in the Power Control Panel Icon? Any help / advice would be appreciated. Thanks.
