envstat issue with -current amd64 lenovo laptop

[Mayuresh <mayuresh%acm.org@localhost>]

On Lenovo v145[1], I was trying out -current (9th May daily snapshot). 9.1
didn't work on this device.

I am getting incorrect envstat output when checking battery status.
Basically looking to extract % charged state using envstat.

envstat output:

dmesg | grep acpibat0.

Probably some BIOS issue. But on the same laptop, on Linux, I am getting
required information from acpi, although there are error messages as
follows in dmesg:

Please advise any further investigation.
