As I say, a more standard kernel would be worth trying, `linux` for 5.16 
and `linux-lts` for 5.15.

Given the age of the W530, acpi_call is the one you want, tp_smapi is 
for older models.

Does the hardened kernel let you mount debugfs to get power usage 
information?

Have you tried with _not_ setting charging thresholds, and _not_ using 
TLP? Does the battery charge when in the BIOS, or booted into the 
archinstall image?
