The Problem:
Every time I restart my computer my Windows 8 power settings go back to default and puts my computer to sleep after an hour. I don't want my computer to ever go to sleep unless I say so... I have to go in Control Panel > System and Security > Power Options > Edit Plan Settings and manually edit the put the computer to sleep setting to Never.
What I want:
A Python script to edit the Power Options in Windows 8. I will set it to run every time I reboot.
I've searched for a Python module to edit Windows settings but couldn't find what I was looking for. I've played with win32api to control my courser a while back but couldn't find Power Options in its documentation.
Julius Caesar's hint about using powercfg command-line options was perfect. Here is the simple script I ended up using:
import subprocess
subprocess.call("powercfg -change -standby-timeout-ac 0")
The -standby-timeout-ac option is set to zero so my computer will Never go to sleep
回答1:
I think You should look into powercfg Windows' command and set whatever You like with python's subprocess.call, for example:
import subprocess
subprocess.call("powercfg -change -monitor-timeout-ac 666")
I guess it is pretty self-explanatory: change '-ac' to '-dc' for battery setting, value is in minutes and zero stands for infinity, obviously.
