Windows 10: Windows 11 drains battery while switched off - Fast startup is disabled

Hello,I have a new laptop with Windows 11, fully updated. It came preinstalled with it. It has been in use for over a month, and I noticed that when I switch it off the battery keeps being consumed. In a couple of days it goes from 100 % to 0 % being switched off all the time, obviously.At first I tried tweaking the Power options in the Control Panel, that includes disabling the fast startup. Nothing worked. I have also tried other things like uninstalling battery-related drivers, the outcome is still the same.I have read many solutions in this forum and other sites too, but those suggestion

:)
