Power Saving for Departmental and Home Systems.

Departmental Systems

    Power Saving for displays

By default all systems should automatically power off any displays currently connected after 30 minutes of inactivity and also power off any internal hard disk drives after 1 hour of inactivity. If this is not the case then please contact ITSupport@Physics.ox.ac.uk. Please always consider manually turning off your monitor whenever you are leaving for desk for any longer period of time.

    Desktop Hibernation/Standby

We also offer the ability to put desktop systems into sleep/hibernation when there are no users logged in. In this state the systems are saving the maximum possible amount of power. Please contact IT support if your system is not power saving correctly or you would like to adjust the power saving scheme.

    Remotely Waking up Systems(This Service Is temporarily UNAVAILABLE)

For systems where remote access(RDP) is required out of hours it is possible to remotely "Wake-up" your machines from anywhere in the world. In order to do this you will need to register your machines for the WOL service. Please visit https://register.oucs.ox.ac.uk/self/wol for both initial registration and also waking up machines. To obtain the MAC address of a machine please do the following. Click start -> Run ->CMD(enter)-> in the command prompt type "ipconfig /all" without quotes and look for the local area connection. The MAC address will be in the following format 00-11-22-33-44-55

Once registered, you will be able to view a list of machines registered to your username and wake them up either on a set schedule or manually on demand. A Wake-up may take from 30 seconds to 3 minutes to fully complete before the machine is in a state where it can receive RDP connections.

    Quick Monitor Off - for use at home or at work.

We also offer a free utility for windows systems which allows users to quickly power off their monitors with a simple move of the mouse. Please download <QuickMonoff.Zip>, Extract QuickmonOff.exe to a folder of your choice and then run it. This will copy the main program to your Start menu -> Startup. From this point on you may simply move the mouse cursor to the top left corner and leave it there for a couple of seconds, this will initiate a quick power off for the monitor. This software has been tested on windows XP, Vista and Windows 7. This software is provided without any form of warranty.

As well as using the quick monitor off application, it is worth checking your power saving settings.
