I want to ask on how I can take off the bios battery or even get through WP so I can turn my brothers Chromebook into a Linux mint Chromebook
read the documentation?
I have the same model, the battery needs to be unplugged to disable WP, personally I used this video as a guide.
Other guides take out the keyboard on this model but I found the method in the video I linked easier for getting to the battery.
Then boot it with a charger plugged in.
Personally I could not boot mine up with it’s 45w charger it comes with, it led to this boot loop where the screen would flash for a second and turn off nonstop.
I then used a charger that had a max output of 22.5W and it booted for some reason, not sure if that was a coincidence but I thought I’d mention it.
