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!

Sounds like an ec issue to me. You can probably get the same effect as removing the battery by turning off the chromebook and holding esc+refresh+power (the same combination used to enter recovery mode on stock firmware).

Thank you for the tip, ill try that if it happens again.
Another thing thats been happeing is after watching twitch or youtube after a couple of hours, just in 1080p… It just becomes unwatchable… like 5fps, until i refresh the page

Any idea here? Thanks a lot
