Hello,

On my Asus NUC 14 Pro +, with W11 24H2, I set a screen off after 5 min. of inactivity.

When screen is off, NUC fan often turns on max speed.

I can't know what is culprit, fan goes quiet again when I return to desktop. No process uses CPU in task manager after that.

Is there a way to know process(es) using CPU heavily when screen is off, like a process monitor ?

Thanks

Well, I found culprit : it's dwm.exe (Desktop Window Manager). I read this with resource monitor.

I launch this before screen off, and read cpu average usage when screen on again.

I'm thinking about my graphics driver, which is integrated ARC on Core Ultra 5 : driver has been published in oct. 2024 according to device manager.

Perhaps a newer version could solve this problem ? I will try next days.

I found culprit behind culprit. dwm.exe panics because of sketchup 2017 when it's loaded during screen off.

Things are getting better when monitor is sleeping after I close sketchup.

Maybe sketchup has an option to avoid this drawback ?
