No Sleep Since 8.1

[ncameron]

I seem to have the opposite problem to many; my Surface Pro refuses to sleep properly since the update, whether I close the keyboard, press the power button or select sleep from the power menu - it refuses to go to sleep.
Very annoying...

A Google search ("windows 8.1 upgrade refuses to sleep") shows you're certainly not alone, though. Perhaps tips on those forums might help?
