Wake my PC FAQs

I clicked the 'Wake up this computer' link next to my computer’s name, but I still can’t access it.

Wait for a few minutes to give the machine time to boot up. Remote Desktop Gateway (RDG) is one of the last services to start in Windows when the computer turns on.

If two minutes pass and you still can’t access it, try to wake it up again, as some computers go back to sleep immediately after being woken up for the first time. If this doesn’t work, contact the ICT Service Desk.

My staff computer doesn’t go to sleep by itself. What should I do?

Ensure that you have not opted out of the power saving scheme.

Meanwhile, put your computer to sleep by double-clicking the green Sleep icon on your desktop or by selecting the Sleep option from under the Shut down options in the Start menu. If you do not see the Sleep icon on your desktop, restart your computer once.

Does this service work on all Linux machines?

The Linux operating system has not been fully tested with this service yet. However, the service has worked successfully on some types of Linux.

I followed the instructions but I cannot make the VPN connection work from home. Can I use this service?

You do not need to use VPN to wake up your computer.

Once you’ve set the service up on your staff computer, you just need to go to www.imperial.ac.uk/wakemypc and then follow the instructions on remotely access my College computer.

I don’t know which computer listed on the Wake my PC page is my main staff computer/my computer isn’t listed.

All of the computers that you are the ‘primary owner’ or ‘custodian’ of will be listed on this page, so it may be a long list.

If you go to the Start menu on your staff computer and select My Info from the options, you will find information about the machine, including asset number and computer name.

Alternatively, you can contact the ICT Service Desk to identify your staff computer, add it to your list or remove the computers for which you are no longer the custodian.

I’m not sure if my staff computer is on or off. Will I be able to use the service if it’s already awake?

No, this request will only turn your computer on when’s it off or sleeping. If it’s already on, it will have no effect.

I’m going away for a while. Will I still be able to wake my staff computer up when I’m back home?

You can wake up your machine up to 45 days after you last switched it off.

If it has been more than 45 days, it won’t work and you will need to turn on your machine and put it back to sleep again.

How do I turn off my machine after using it remotely?

Display your desktop by closing or minimising all of the windows, then press the Alt and F4 buttons at the same time. This should display the Shut Down Windows screen, where you can select the appropriate option.

Alternatively, use the green Sleep button on your desktop to put it to sleep.
