Wake Windows PC from sleep in Python 2.7

Question

I have a script that will put the system to sleep in the middle of it. Is there any way to make that script wake the system up and then continue running?

I have read man

Answer 1

I was unable to accomplish this using just python. However in the Windows SDK they provide a tool called pwrtest that will allow you to do timed sleep cycles. I am able to call this with python and then my script continues when pwrtest wakes the PC up from sleep.

Answer 2

It depends on how you're putting the system to sleep. If using SetSuspendState (with the last argument being FALSE to allow wake-up events), then you can schedule a future wake-up using CreateWaitableTimer followed by SetWaitableTimer.

The respective Python implementation is quite easy using ctypes or, if you want something more pythonic, pywin32.

Hope it helps!
