Battery charge threshold
Kernel 5.4 brought the ability to set the battery charge threshold for some Asus laptops, by modifying the charge_control_end_threshold variable exposed under /sys/class/power_supply/BAT0/[1][2].
By default this value is set to 100 and reset on every power cycle[3].
The effect of its change can be demonstrated as follows:
$ cat /sys/class/power_supply/BAT0/status Charging $ cat /sys/class/power_supply/BAT0/capacity 74 # echo 60 > /sys/class/power_supply/BAT0/charge_control_end_threshold $ cat /sys/class/power_supply/BAT0/status Not charging
Note: As of 2020-12-11, the following battery device names are recognized: BAT0, BAT1, BATC and BATT.[4] Adjust accordingly or use the single character wildcard (
?), e.g. BAT?.systemd service
In order to automatically change the value at boot, create the following systemd service:
/etc/systemd/system/battery-charge-threshold.service
[Unit] Description=Set the battery charge threshold After=multi-user.target StartLimitBurst=0 [Service] Type=oneshot Restart=on-failure ExecStart=/bin/bash -c 'echo 60 > /sys/class/power_supply/BAT0/charge_control_end_threshold' [Install] WantedBy=multi-user.target
and then enable it.
Tip: Replace
60 with the desired value.Restart=on-failure and StartLimitBurst=0 are used to work around the service failing with a /bin/bash: /sys/class/power_supply/BAT0/charge_control_end_threshold: Permission denied error.
This error is due to the service being started before asus-wmi could be loaded by the kernel (noted as kernel: battery: new extension: ASUS Battery Extension in the journal), making it impossible to write there.
The combination of those two options allows unlimited restart of the service for DefaultStartLimitIntervalSec (set to 10 seconds by default in /etc/systemd/system.conf), leaving enough time for the sysfs path to become available and writable and thus ensuring the fastest execution of the service.
Note: As of 2020-12-01, this is the only functional workaround as neither path-based activation or systemd-tmpfiles were working.
udev rule
The battery's charge_control_end_threshold power supply class attribute does not initially exist. It is added to the sysfs(5) directory by the asus-nb-wmi kernel module. Create a udev rule for asus-nb-wmi to set the battery's charge threshold:
/etc/udev/rules.d/asus-battery-charge-threshold.rules
ACTION=="add", KERNEL=="asus-nb-wmi", RUN+="/bin/bash -c 'echo 60 > /sys/class/power_supply/BAT?/charge_control_end_threshold'"
Persist after hibernation
While this setting will persist after suspending to RAM, it will be reset when resuming from hibernation. In order to re-execute the service after hibernation, use one of the methods described in Power management#Sleep hooks.
E.g. if using Power management#Generic service template, enable an instance of the created template using:
# systemctl enable [email protected]
If creating a script as described in Power management#Hooks in /usr/lib/systemd/system-sleep, use something similar to:
/usr/lib/systemd/system-sleep/battery-threshold.sh
#!/bin/sh
case $1/$2 in
pre/*)
echo "Going to $2..."
;;
post/*)
echo "Waking up from $2..."
echo 60 > /sys/class/power_supply/BAT0/charge_control_end_threshold
;;
esac
Do not forget to make the script executable.

| VivoBook M513IA | 2021-09-12 | Yes | Yes | – | Yes | Yes | Yes | – | See #Function key behavior | |
| VivoBook F510UA | 2018-07-01 | Yes | Yes | – | Yes | Yes | Untested | – | UEFI secure boot key rejected, had to disable in BIOS. | |
| VivoBook 14 X442UA-GA139T | 2018-05-01 | Yes | Yes | Yes | Yes | Untested | Untested | – | UEFI secure boot does not pass, might need work. | |
| VivoBook S301LA | 2016-09-01 | Yes | Yes | Yes | Yes | Yes |
acpi_osi= needed for hotkeys and backlight control. For package power states lower than PC3, see Remarks. |
– | To reach PC7, r8168 has to be built without certain build options. An easy way to do this is to build r8168-dkmsAUR after modifying its dkms.conf by removing EXTRA_CFLAGS='-DCONFIG_R8168_NAPI -DCONFIG_R8168_VLAN'
|
|
| VivoBook X512DA | 2019-03-15 | Yes | Yes | – | Yes | Yes | Yes | – | See #Function key behavior | Fan spins unusually fast when started plugged in. |

| VivoBook X509DA_D509DA | 2021-06-21 | Yes | Yes | – | Yes | Untested | Bad battery life fan always spins |
– | Sometimes the touchpad is not recognized, to fix run # rmmod i2c-hid-acpiand # modprobe i2c-hid-acpi |
Needed an external wifi/ethernet adapter (via USB) during archiso (for access to internet), screen brightness is set to lowest when you plug/unplug your power for the first time after boot (now fixed, i think by adding the amdgpu module in /etc/mkinitcpio.conf)
|
| VivoBook Pro 14 (M3400) | 2021-04-29 | Yes | Yes | – | Yes | Yes | Yes | – | A few keys were strangely mapped (e.g. Screenshot key Fn+F11 mapped to Super+S). |
Recovering from DPMS brightness reset to default can be solved by replacing acpi_video0 with amdgpu_bl0.
|
| Vivobook X450LCP | 2019-11-01 | Yes | Yes | Yes | Yes | No | Yes | – | Touchpad works better with deprecated xf86-input-libinput driver | Apparently there is no way to control manually the fan. Every time the fan just stops spinning, needing suspending/reboot to fix. |
Function key behavior
The Function keys default behavior is F1,F2,etc… and must be unset by using Fn+Esc to use alternative functions.
