Since almost over a year my internal battery is not charging or powering my ThinkPad.
I always have this Power Manager output for BAT0:
I also get the following output from tlp command:
# tlp recalibrate BAT0
Setting temporary charge thresholds for BAT0:
start = 96 (no change)
stop = 100 (no change)
Error: discharge BAT0 malfunction -- check your hardware (battery, charger).
Battery recalibration aborted.
Checking the Diagnostics UEFI on boot shows everything but a battery module for testing.
If I unplug the external battery the laptop turns off immediately so I guess my internal battery is just dead.
These are my questions:
Why is BAT0 still shown with the information from Power Manager?
Is the battery just dead or could it be a problem with the motherboard? What can I do to be sure?
Why does it not show up in the diagnostics menu?

i hate to quote reddit but it seems to be the relevant info:

this part mainly:
I switched from Legacy BIOS to UEFI, updated my bios and firmware to the latest versions, re-installed Linux, and batteries are now switching as needed, without need for the above script.
