Battery draining

[raulsimcic]

Hi!

I have an old Microsoft Surface Pro 4 on which I installed Atlas OS following the instructions (clean Windows installation -> Atlas OS). I noticed that after installing Atlas OS the battery drains even when the laptop is shut down normally (Start -> shutdown). Basically, I can say that the battery drains almost as if the laptop isn’t turned off (but it is or it seams so) – I charge it overnight, in the morning I unplug it, and after 2-3 hours when I turn it on, the battery is either completely dead or almost completely drained. In normal usage the battery lasts for 2-3 hours depending on workload. Has anyone else experienced similar problems, and is there any way to fix this? I'm not sure if this is related to Atlas OS but with a regular Windows 11 installation I didn’t notice such battery drain.

Thanks.
