The WOL system can wake your machine up automatically on a schedule. We can offer three wake-up schedules: 6am Monday to Friday, 8am Monday to Friday or 8am Monday to Thursday. If you would like to include your computer in one of these schedules just email ithelp@stats.ox.ac.uk with your computer's name.

The WOL system can only work on computers on the main Statistics network.  Only machines where we retain sole administrative control are allowed onto the main network. As laptops are all on the Private network they cannot be woken with WOL.

Will the machine automatically turn off?

No, at the moment we would like you to turn your machine off when you are not using it. Over the next few months we are looking at developing a system for turning off machine which are idle but we will give plenty of warning before this is introduced.
