University Policy on Switching off PCs
   Q:   Should I switch off my PC at night ?

Yes! To reduce overall energy consumption, it is recommended that staff shut down their desktop computers overnight and before going on leave. This will lower your carbon footprint and significantly reduce your departments' energy bill. For further details please read the attached "Switching off PCs Policy" document.

How can I be more energy efficient?
You can be even more energy efficient by putting your PC into “sleep” mode whenever you leave your desk for any length of time. Use this option to save power, especially if you prefer to leave your computer turned on for long periods of time. In sleep-mode, your computer is available for immediate use - just log on and your desktop is exactly the same way that you left it, including any programs that you were using.  Click on the Windows logo at the bottom-left of your screen, and select "Sleep" from the little menu to the right of "Shutdown". (There's a ">" arrow to the right of it).
Note 1: When in sleep-mode, information in memory is not saved to your hard disk. This means that if the computer loses power, any information that you did not save before the computer went into sleep is lost.  It's a good idea to save your work before putting the computer to sleep.
Note 2:  If your PC is in sleep-mode you may not be able to connect to it using the Remote Desktop Connection facility. If you need to connect remotely you should use the log-off option.
