Hello,

I had an acer tablet running windows 10.
I could easily turn off the screen WITHOUT putting the tablet to sleep with several solutions:

via nircmd.exe :
nircmd monitor off

standby via SendMessage :
SendMessage, 0x112, 0xF170, 2,, Program Manager

When I send these commands, the screen turns off and all programs still run.
A simple touch on the touch screen turns the screen back on, and the tablet is still into the same screen.

Today I have a Surface Pro 7 running Windows 11.

The problem is that the two command above turn off the screen, but :

- all the programs goes to sleep
- I have to press the power button, the touch surface does not wake up the tablet
- once the power button is pressed, I get the lock screen window.

Would there be an equivalent to the old method that I used in windows 10 ?

Thank you,

Aramas, this question can best be answered by any surface users her. Change the title of your thread to get their attention. Use something like Surface Pro 7-How can I turn off screen without putting to sleep

PS: I read many posts on the Microsoft forum about the Surface dating back to 2013 with folks complaining about the exact same problem. I never saw a definitive answer.

Hello all,

If someone need it too, I "solved" it by doing all these steps :

Bringing back hidden options in battery performance :
So you can config sleep mode to just turn monitor off and still continue to use app ( listen music with screen off for example )

Disable lock screen :

Disable login screen :

By doing all these steps, trying to turn off the screen with a shortcude with nircmd or SendMessage to programmanager still not work.
App goes to sleep.
BUT
Workaround that I found is to use this cmd :

  • powercfg -change -monitor-timeout-ac 1

This cmd set the time for the screen to turn off in 1 minute.
After you can set it to 0 so it desactivate it.
You can automate this cmd with domotic program.
