Battery report false in kernel 5.13.0-40-generic

[Dave Goldsbrough]

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.

I have replicated the issue. Whilst logged into kernel 5.13.0-40-generic I removed power cable for a minute or so, re-inserted power cable and my battery indicator showed 96% and not charging.
Restarted machine logging into kernel 5.13.0-39-generic and the battery indicator shows 100% and fully charged. See attached screenshots.

Thank you Dave for doing the work of reporting this issue. I have exactly the same problem on my Thinkpad X1 Carbon. I'll be glad to try to help if any complementary info is needed.

[Dave Goldsbrough (daveg-k)]

Recently updated kernel to 5.13.0-41-generic and the problem remains.

[Dave Goldsbrough (daveg-k)]

I keep updating the kernels as they are released. Every one to date has the same problem. I have retained 5.13.0-39 where the problem does NOT exist.

[Tobias Assmann (tobias-assmann)]

Same Problem with an kernel 5.15.0-70-generic on Thinkpad X1 Carbon Gen. 9
