Title:
Battery report false in kernel 5.13.0-40-generic
Status in linux package in Ubuntu:
Confirmed
Bug description:
Description: Ubuntu 20.04.4 LTS
Release: 20.04
I think this is a power management, kernel and/or firmware issue.
My laptop is old Lenovo T410.
After recent updates my battery indicator shows a reduced percentage
charge and reports is not charging. This is after booting into kernel
5.13.0-40-generic.
If I reboot into kernel 5.13.0-39-generic the percentage charge does
drop from 100% to 94% when unplugged. It reports that it is charging
when plugged back in with an estimate of 14 minutes until full. This
is what I would normally expect.
