Lenovo Thinkpad Yoga C13 (Morphius) very strange issue

So I followed the guide here : How to install Windows 10/11 on a Chromebook

and installed windows, everything worked fine.
Keyboard, wifi, sound, touchscreen, cameras, rotation, touchpad, nub… really everything.
EXCEPT, keyboard backlight, but I don’t mind TBH

Suddenly (after like 2 days of using it with no problems) the system starts feeling very sluggish… like 2 seconds wait for right click menu to appear. So I give it a restart.

To my surprise the keyboard backlight works now, BUT everything else is broken…

No sound, no wifi, no rotation, no nub no touchpad, basically everything except the keyboard broke…

Trier restarting a few times with no help, tried system restore, nothing helped…

It was very slow to even show the boot logo and enter bios so I was thinking its not a windows issue but UEFI/bios related.

So I go to unplug the battery and reflash UEFI, but I instantly notice the fast bootup.
I enter windows just in case, and EVERYTHING works again…

Unplugging the battery fixed it…

Plugged the battery back in restarted a few times… everything is good now, I’m using it to type this.

So I wanted to ask why this happened? Is this common knowledge to have to replug the battery every now and then?

I guess its just a CMOS reset that fixed it?

This is my first chultrabook, any advice would be appreciated thanks!
