I tried some different searching and came across this:

These are my symptoms but I'm unclear on the implications of removing
UPower. Any thoughts on this?

I'm seeing some new behavior recently where my laptop shuts down
hard,
with no warning, at about 50% battery. After the third time it happened I
took a look at the battery levels (after plugging in and restarting) and
found that the main battery was at 1% and charging, while the extra battery
was at 100% and fully charged.
So it would seem that my system is ignoring the extra battery or somehow
not tapping into it at runtime. I don't recall this ever happening in the
past and I'm not sure if this is an OS issue or something lower level.
Anyone seen or know how to diagnose this?
Thanks!
