As I say, a more standard kernel would be worth trying, `linux` for 5.16
and `linux-lts` for 5.15.
I've installed the 'linux' kernel package and 'linux-headers'. That did
allow me the ability to run powertop.
Given the age of the W530, acpi_call is the one you want, tp_smapi is
for older models.
I thought so, but wasn't sure. Thanks for clearing that up.
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?
When I first installed linux over a few days the capacity had dropped
from near 50% down to where it is now. It's hard to say now which
packages were missing at that point, and in the very beginning I wasn't
monitoring capacity bc I hadn't had any issues yet. The first thing I
noticed was from the first day my runtime was cut in half after
switching to linux and decreased pretty dramatically.
Last night, when I read your reply, I tested it with the bios.
This is the output of tlp-stat -b afterward:
