Two batteries (Thinkpad T580)

[wujastyk]

Is your feature request related to a problem? Please describe.

The Thinkpad T580 has two batteries: one internal and one removable (the usual kind). As far as I can see, slimbookbattery only addresses the internal battery.

Describe the solution you'd like

Slimbookbattery to recognize multiple batteries.

Thanks!

Hello @wujastyk

This project use as backgroud TLP

I think you need install tp-smapi-dkms and acpi-call-dkms as is describe in the arch linux doc

I confirm this on my T480.
tlp is reporting it correctly (see below), but slimbookbattery is not.

  Parameter value ranges:
• START_CHARGE_THRESH_BAT0/1: 0(off)..96(default)..99
• STOP_CHARGE_THRESH_BAT0/1: 1..100(default)

Work-around... you can use tlp-UI to individually control charge-levels of each of 2 batteries in lenovo laptops like X240. Conky can also show both bat0 and bat1 as well, as shown in screenshot.
