How can I prevent Windows 10 from any kind of sleep or hibernate when running python script?

Question

I'm running a python script, which takes a couple of days. But Windows 10 seems keep pausing the script after some time, i.e. when I leave for a while the program stops (screen off also), but when I come back and do whatever things, the program will resume. Although I change all the power options in Windows 10, like

"never go to sleep when plugged in"

"never turn off hard disk"

"allow hybrid sleep: off"

"never hibernate"

Extra information: Windows edition: Windows 10 pro; 64-bit Operating System, x64-based processor;

python: Python 2.7.12 |Continuum Analytics, Inc.| (default, Jun 29 2016, 11:42:13) [MSC v.1500 32 bit (Intel)] on win32

Solution 1

Use the tool Don't Sleep while running your python script:

Don't Sleep is a small portable program to prevent system shutdown, Standby, Hibernate, Turn Off and Restart.

This prevents all action that can interrupt your script.

Solution 2

Runs a program preventing sleeping or the display turning off while the program runs. Doesn't affect the screensaver.

Using pywin32 library you can do exactly the same. I note that pywin32 doesn't actually wrap this function.

For more info see docs https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-setthreadexecutionstate

NOTE: Do not use the constant ES_USER_PRESENT as it will always fail.

From above link

ES_AWAYMODE_REQUIRED 0x00000040 Enables away mode. This value must be specified with ES_CONTINUOUS. Away mode should be used only by media-recording and media-distribution applications that must perform critical background processing on desktop computers while the computer appears to be sleeping. See Remarks.

ES_CONTINUOUS 0x80000000 Informs the system that the state being set should remain in effect until the next call that uses ES_CONTINUOUS and one of the other state flags is cleared.

ES_DISPLAY_REQUIRED 0x00000002 Forces the display to be on by resetting the display idle timer.

ES_SYSTEM_REQUIRED 0x00000001 Forces the system to be in the working state by resetting the system idle timer.

In the power plan, I also chose the High performance

[Admin]

Settings->power and sleep->[set the screen and sleep times to 'never']

[Admin]

@ssaltman, that's the first example I listed above, "never go to sleep when plugged in"
