[solved][x1c3] battery no longer charges ..., does charge in Win10

I used https://push.cx/2015/battery-longevity in hopes of improving the battery's longevity.
Recently I noticed the battery isn't charged when connected to an outlet.
I have dual boot, booted into win10, and noticed under win10 it still charges.

This makes me believe something has gone south with "tpacpi-bat"? What could it be?

"pacman -Q | grep acp" gives:

acpi_call-dkms 1.1.0-5
tpacpi-bat 3.1-1

It may be that acpi_call-dkms is to blame? I recently installed it because I have multiple kernel versions I can select from.

What does the journal say when you connect to AC? Have you tried uninstalling battery-longevity?

Please read How To Ask Questions The Smart Way and make some effort to help yourself.

Re: [solved][x1c3] battery no longer charges ..., does charge in Win10

I ended up removing tpacpi-bat. After that the battery accepted charge.
Reinstalling tpacpi-bat caused the same issue: battery not charging.

My /usr/lib/systemd/system/tpacpi-bat.service seems wrong. Any tips?

[Unit]
Description=sets battery thresholds

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/tpacpi-bat -s ST 0 40
ExecStart=/usr/bin/tpacpi-bat -s SP 0 80
ExecStop=/usr/bin/tpacpi-bat -s ST 0 0
ExecStop=/usr/bin/tpacpi-bat -s SP 0 0

[Install]
WantedBy=multi-user.target

From a post on /r/thinkpad I learned how to limit the charging to 80% (Lenovo Utilities) for now.
Do I need tpacpi-bat for anything other than charging limits?

The service says that the battery shall not charge unless charge drops below 40% - does that meet your perceptions?

tpacpi-bar comes with a readme that explains those commands and I suggest to read that instead of "a post on /r/thinkpad" ...

Thanks for pointing out there is a README. Reading it is indeed correct advise. Found a README here:
https://github.com/teleshoes/tpacpi-bat … /README.md

The post on /r/thinkpad was on Lenovo Utilities on Win10, not about tpacpi-bat.
