Hi all,

Based on the dmesg messages from the original reporter:

[ 4.964073] ACPI: _SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error [ 4.964083] thinkpad_acpi: Error probing battery 2

Lenovo ThinkPad X131e also needs this battery quirk.

I forgot to include a Cc to stable. This issue dates back to as far as 5.19 (the oldest version available in our distro repository).
