T14 AMD Gen 1 20UDCTO1WW: BIOS 1.30 drains battery when powered off

2021-01-25, 5:39 AM

This is when the laptop is powered off, not sleeping.  I updated from 1.29 to 1.30 a few days ago, then immediately noticed this problem.  Reverting to 1.29 resolved it.

Hello dimitris321!


Welcome to community forums.


Good to hear you were able to resolve it. Kindly wait for the BIOS future update from the website;  https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14-type-20ud-20ue/downloads/driver-list/component?name=BIOS%2FUEFI

Update us soon if the issue is still present.

@samsonwong I happened to have the old ISO file around. But I see that the HK support site also has a few previous releases available:

I had to disable both secure boot and rollback protection from the BIOS security settings in order to flash the rollback. (edit formatting)

You need to disable the Secure Rollback Prevention in the BIOS first. Here is how to boot to BIOS: https://support.lenovo.com/us/en/solutions/ht500222-recommended-ways-to-enter-bios-boot-menu-thinkpad-thinkcentre-thinkstation


You can download and install the BIOS version 1.29 here:  https://download.lenovo.com/pccbbs/mobiles/r1buj60w.exe

I can confirm that there is an issue with BIOS version 1.30.

 

I experienced drastic battery drain in hibernate and shutdown state with version 1.30. Downgrading to 1.29 solved the issue.

PSA: 1.30 is now available for Linux users via lvfs, probably makes sense to hold off

2021-02-26, 0:25 AM

Pretty much what the subject says, I got a notification that 1.30 is available via LVFS/fwupd, holding off of course.

@Jwes_Lenovo 

Facing the same problems here with the T14 and BIOS 1.30 - are there any news about a fix?

Kind Regards

@Jwes_Lenovo 

the last reply here is one month ago - are there any updates from Lenovo's side?

It's still an annoying bug and the 2 known workarounds (change Sleepstate in BIOS to Windows and Rollback to 1.29) are no options for me :/
