Battery capacity reported as 0% after firmware upgrade on Thinkpad P15 Gen 2i (Model 20YRS0BM00)
Hello,
After recent EC and BIOS firmware updates on a brand new Thinkpad P15 Gen 2i (Model 20YRS0BM00) via fwupd/LVFS, battery charge information has disappeared and charge status is reported as 0%. Interestingly, the battery charge percentage indicator was fine through a couple of charge/discharge cycles on stock firmware (i.e., before upgrade).
Diagnostic information below.

Let me know if you need further information to diagnose this issue.
Thank you.
Also, attempting to downgrade the firmware via fwupd results in the message Check power failure, please insert the power source or charge the battery. after rebooting despite the AC charger being plugged in. This seems to be a similar issue encountered in #348 and #350. Can you provide instructions for working around these power checks when downgrading the firmware?
@ohearnk thanks for reporting this problem. Have you tried the pin hole reset? https://download.lenovo.com/pccbbs/pubs/p15_gen2_t15g_gen2_p17_gen2/ug/html_en/index.html#t=en%2FBottom_view.html&rhsearch=hole&rhhlterm=hole&rhsyns=%20
@ChiWei-Chen Thank you for the response. Can you clarify whether the pin hole reset is meant to resolve the battery capcity being reported as 0% or is it meant to allow firmware downgrade / reinstall? If it is the latter, I still am receiving Check power failure, please insert the power source or charge the battery. when trying to downgrade the firmware.
Also, after trying the pin hole reset a few times, I did monentarily see a non-zero battery capacity upon rebooting without the AC adapter connected to the system. However, after a few seconds the capacity reverts back to zero. And there are different results from upower and journalctl:

@ohearnk , thanks for the feedback. I shared this with FW team, I'll let you know if any progress (LO-2670 for tracking internally.)
@ohearnk , as our team cannot reproduce this issue on multiple machines (with BIOS version 46w(1.27) and EC 30W(1.12)) and suspected this could be a HW issue. Please contact customer support for this issue. Thanks!
This seems to be a similar issue encountered in https://github.com/fwupd/firmware-lenovo/issues/348 and https://github.com/fwupd/firmware-lenovo/issues/350.
They are different issue (BIOS/Battery FW), even the behavior seems similiar.
