pywin32 : scheduled weakup from standby/hiberate ?

[robert]

On Windows the task scheduler tool can program (the BIOS?) to weak up
the machine from standby/hibernate at certain pre-configured times. Can
this be done directly through the (py)win32 API?

What you need is a Waitable Timer.

The APIs to manipulate these are:

win32event.CreateWaitableTimer()
win32event.SetWaitableTimer()
win32event.CancelWaitableTimer()

The wakeup feature is enabled when the last parameter of the call to
SetWaitableTimer is True.

However, pywin32 seems to be missing a binding for the
SetThreadExecutionState() function so unless a person moves the mouse or
keyboard within a minute or two of the wakeup, the system just goes back
to sleep.

You should be able to call the SetThreadExecutionState function using
ctypes.

Search for Power Management in the MSDN library for info on these functions.

Pywin32 has a taskscheduler module that can be used
to create a scheduled task to wake up your system.
The TASK_FLAG_SYSTEM_REQUIRED flag
corresponds to the "Wake the system to run this task"
option in the UI.
