Re:T14 AMD battery drain in standby (Linux)

2021-04-05, 13:01 PM

Hi @ikovnatsky 

 

FW team are testing a new EC that they expect to solve the problem. I've not loaded it on my system myself yet to try it but plan to do so.

 

I'll update once I have some results - I don't believe the batteries are faulty.

Hi @linuxmad 

 

No ETA, but it's under testing and if it fixes it I'd hope they get it out fast. I'll check in with the team but as a note it's a holiday in China today.

Mark, thanks for the update. Could you please clarify what is being (hopefully) fixed? The initial issue of battery drain during standby or the regression introduced in 1.30 (battery drain when powered off)?

Sorry - missed that part.

This is for the power drain when powered off. There is separate work going on for the standby issue.

FWIW, I've been in touch with Lenovo support. Outcomes, so far:

  1. Was asked to run "Lenovo Vantage"... Persistently.
  2. Re-imaged with Windows recovery ISO obtained from Lenovo, ran the test. Sent the screenshot, no errors visible.
  3. Was asked to provide a log from UEFI diagnostics.
  4. Ran the diagnostics. Surprise-surprise, battery reported an error, something along the lines of "diverging lifespan mode value".
  5. Sent UEFI report to Lenovo, now waiting for an update on when they can replaced the battery and if this a matter of battery at all or some other circuitry.

Chasing other newly-purchased Lenovo systems to run the UEFI test...

I am also getting the same error in UEFI diagnostics for the battery with regard to diverging lifespan mode value.

 

Mine is a Thinkpad T14 AMD, built mid-November 2020.
