Software to disable Sleep Mode

If all else Fails or you want to be 100% sure you can use Insomnia. This little app stops your computer going to sleep while it is running but there isn’t any mouse or keyboard activity, when you are controlling it remotely, for example. The window remains open while it runs (although it can be minimized), and while it’s there, your computer is unable to go asleep.
