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.

Does it have dual batteries? My t470s does a hard shutdown instead of switching battery source when the first battery is empty sometimes. It's an old bug and I think the consensus is that no one is really sure why.
Yes, it does have two batteries. That kind of sucks. But I don't need all-day battery life, so hopefully that won't be a huge issue.
Hopefully you won't get bitten by this bug. It seems like a combination of Lenovo firmware, upower, and the DE.
I hope not, but if it is an issue, it doesn't sound like it will be a huge one most of the time at least.
Is your internal battery dead? I've never seen such problems with dual battery Thinkpads.
No, both work, it's the switching over that often does a hard shutdown.

I'm using the latest Lenovo firmware and have the same issue in any Linux version I've tried. Bad luck I guess, but I'm out of ideas.
I can't speak for the T460, but I have a T480 with dual batteries and battery swapping works just fine. With a bit of tinkering I was even able to get the fingerprint sensor to work as well
Much like my searching, it seems like it's all over the map in terms of experiences, although in general, it seems like the issues people have encountered are minor.
Fwiw I never had a problem hotswapping batteries out
