I have a problem, the battery do not really charge, 100% is reach in few minutes, and it works less than 15 minutes on battery. Is anybody have a solution ? Bios update maybe ?
I got to pull out my bloated battery…. Though it could work with just the charger on stand by but it did not… Anyone knows where I can purchase new battery? Can't bring it to the shop because of quarantine but need to work from home.
I removed the bloated battery too. It can’t power on properly. The power light just just on and off around every 5 seconds. Is yours the same?

after I change the battery it always says plugged in not charge, anyone has the same issue?
Hi. There is no page for keyboard replacement so I'm asking my question here: how can I find a keyboard replacement for my mi 12.5 notebook? Only two buttons do not work.
Hi! your tutorial is really great! Helped a lot. Thanks for posting this!
Some hint that may be helpful for others: I bought a replacement battery from company KingSener at Aliexpress. At first it seems to fit very well, but after remounting everything I found out that the clickpad doesn't work correctly. It just doesn't click anymore because the replacement battery is somehow thicker and hinders the clickpad. I then opened it again and saw that in the replacement the two middle cells are somehow smaller than in the original battery. The empty space is filled with a pad of flexible foam that is even thicker than the cells. I removed part of it with a knife (be sure to not damage the cells!) and assembled again. Now the clickpad is working as expected (or at least very close to, I am not totally sure).
