How to make a Windows 10 computer go to sleep with a python script?

问题

How can I make a computer sleep with a python script?

It has to be sleep, not hibernate or anything else.

I have tried to use cmd but there is no command to sleep or I didn't find one.

回答1:

You can use

import os
os.system("rundll32.exe powrprof.dll,SetSuspendState 0,1,0")

If this command doesn't work for you (it actually puts your comp. in hibernation mode) you will need to turn hibernation off:

Powercfg -H OFF

To turn hibernation mode back on:

Powercfg -H ON

Alternatively, you can also use:

Rundll32.exe Powrprof.dll,SetSuspendState Sleep

If you don't want to turn hibernation off just to run a command, you can use psshutdown as an alternative

C:\Windows\System32\psshutdown.exe -d -t 0 

As for what os.system does, straight from the documentation:

Execute the command (a string) in a subshell.

An additional note:

You will need to have administrator permissions to run Powercfg -H *

回答2:

rundll32.exe powrprof.dll,SetSuspendState 0,1,0 

should work. Note 0,1,0 - that set is for sleep. Without - hibernation.
