Linux Laptop Power Management TLP

TLP is an advanced power management tool I use for my laptop that runs Linux. I have not tested the different settings, but it seems that the battery time is increased compared to not running it. :-) I only use it in battery-mode. There are some extra features for Thinkpad laptops.

TLP settings file Ubuntu: /etc/tlp.conf

Reload config: sudo tlp start

Check TLP status: sudo tlp-stat 

Check battery: upower -i /org/freedesktop/UPower/devices/battery_BAT0

Set charge: sudo tlp setcharge 40 80

Battery status 2021-12-06:

+++ Battery Features: Charge Thresholds and Recalibrate

tpacpi-bat = inactive (kernel module 'acpi_call' load error)
