In order to reduce the amount of energy that your PC consumes, Windows 7 has been configured to go to sleep when it hasn’t been used for 30 minutes. This puts your PC into a state where it is using only the smallest amount of energy required to keep it going. It is woken up when you use the keyboard or mouse, and comes back to life in a couple of seconds.
If you use the Remote Desktop facility to access your computer from outside the University, you will need to wake it up before you can use it, as Remote Desktop cannot connect to your PC when it is asleep. You can do this with the new Wake on LAN service, available from MyEd. The instructions for this are available at the foot of our "Working from Home" advice page:
It is likely that your PC will be given a new name when it is first upgraded to Windows 7. If you have already been using the Wake on LAN service on your Windows XP PC, you’ll need to re-register under Windows 7 by adding it to your “My Wake List” again.
