From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My Thinkpad T480s randomly dies with Arch Linux (sh.itjust.works)

I can’t find an active thinkpad centric community on here I am just going to post here. My Thinkpad T480s, 16 GB RAM, 238 GB SSD is randomly shutting off while at like 50%. When I try to open it back up it always is dead and I have to connect charger to boot it up again. Why is this happening? Is it battery issue? It complains about not being able to read temp2_input while shutting down and sometimes say PM usage count underflow. Not sure what that is supposed to mean.

Oh, wait. 50% and Thinkpad. I used to have a Thinkpad with two batteries.

That looks like the T470s has a dual battery, and unlike mine, they look like they're the same size. Does your T480s have dual batteries?

EDIT: The T480 apparently does. Does the T480s?

EDIT2: I don't see anything that looks like a second battery myself in this:

So I'm guessing not.
