Hello guys
Before I write anything on topic, let me inform you that I am a complete newbie. I started playing with linux around a month ago with Arch. I decided to swap to Artix because of the absence of systemd, and now I experience my first real inconvenience that i cannot fix.
Namely, I want to have a charge threshold. I have a laptop that is plugged in nearly at all times when I am not at my university. Windows gave me the option to set the charge threshold to 60%, so that is what I want to stick with.
My goal:
Have my laptop charge to around 60%
Bonus goal: Let it fluctiate between 55 and 65%
What I've tried:
1. TLP
Here is a fragment of my tlp.conf file concerning charge thresholds
# BAT0: Primary / Main / Internal battery (values in %)
# Note: also use for batteries BATC, BATT and CMB0
# Default: <none>
START_CHARGE_THRESH_BAT0=0
STOP_CHARGE_THRESH_BAT0=60
# BAT1: Secondary / Ultrabay / Slice / Replaceable battery (values in %)
# Note: primary on some laptops
# Default: <none>
#START_CHARGE_THRESH_BAT1=75
#STOP_CHARGE_THRESH_BAT1=80
# Restore charge thresholds when AC is unplugged: 0=disable, 1=enable.
# Default: 0
RESTORE_THRESHOLDS_ON_BAT=1
# Control battery care drivers: 0=disable, 1=enable.
# Default: 1 (all)
NATACPI_ENABLE=1
#TPACPI_ENABLE=1
#TPSMAPI_ENABLE=1
and my tlp-stat -b with my quick fix
SkvShkr% sudo tlp-stat -b
--- TLP 1.5.0 --------------------------------------------
+++ Battery Care
Plugin: asus
Supported features: charge threshold
Driver usage:
* natacpi (asus_wmi) = active (charge threshold)
Parameter value range:
* STOP_CHARGE_THRESH_BAT0/1: 0(off)..100(default)
+++ Battery Status: BAT0
/sys/class/power_supply/BAT0/manufacturer = ASUSTeK
/sys/class/power_supply/BAT0/model_name = ASUS Battery
/sys/class/power_supply/BAT0/cycle_count = 96
/sys/class/power_supply/BAT0/energy_full_design = 67292 [mWh]
/sys/class/power_supply/BAT0/energy_full = 61232 [mWh]
/sys/class/power_supply/BAT0/energy_now = 58761 [mWh]
/sys/class/power_supply/BAT0/power_now = 9583 [mW]
/sys/class/power_supply/BAT0/status = Charging
/sys/class/power_supply/BAT0/charge_control_end_threshold = 100 [%]
Charge = 96.0 [%]
Capacity = 91.0 [%]
SkvShkr% sudo tlp setcharge
Setting temporary charge threshold for BAT0:
stop = 60
2. Custom daemon?
On Arch i could setup a daemon that would set this fix for me, so I tried doing it here:
A) rc.local
#!/bin/sh
# /etc/rc.local -- rc.local for Artix Linux
#
# Enter your custom commands here.
#https://unix.stackexchange.com/questions/48534/how-to-adjust-charging-thresholds-of-laptop-battery
sudo echo 60 > sudo /sys/class/power_supply/BAT0/charge_stop_threshold
B) branding.start
#!/bin/sh
#neofetch --no_config --backend off --color_blocks off --underline off --disable memory gpu cpu icons theme resolution uptime
sudo tlp setcharge
This thing worked. Now when i run sudo tlp-stat -b at boot, my charge threshold is 60%, so my issue is solved
I have decided to share this post wis you either way and get some tips on linux/artix forum.
