not working if the computer is put to sleep mode

[sjv-afk1]

If the laptop is put to suspend, then this feature doesn't work. Also, the persist function doesn't work.

And for example if I use the following command : ./bat --threshold 60, I get asked for root password, but I always get authentication failure. So, I need to use SUDO with it.

This program only works temporarily( During the session). If subjected to suspend or restart, then it fails.

I am using asus tuf a17 FA-706IH
operating system: ubuntu 20.04
kernel: 5.8.0-44-generic

Thank you for bringing up the issue. I will have a look into it.

Just to make sure that I understand,

1. when the laptop is put to suspend (or shut down), the charging threshold is not set anymore upon restart,
2. the persist argument does not work at all,
3. when you run bat --threshold 60 and get asked for the root password you get an authentication failure message but if you use sudo bat --threshold 60 it works?

1. YES ( I mean sleep mode when I say suspend) So, if I resume from sleep mode, then threshold is reset to 100. ( However, in the command line it shows that threshold is 60, but I can see my laptop charging towards full capacity)
2. YES
3. YES

Do you get any message after running sudo bat --persist?

no

[tshakalekholoane]

Can you run the following command, test -f /etc/systemd/system/bat.service && echo "TRUE" and tell me what you get out?

[sjv-afk1]

Can you run the following command, test -f /etc/systemd/system/bat.service && echo "TRUE" and tell me what you get out?

~/Binaries/bat1$ test -f /sys/class/power_supply/BAT?/charge_control_end_threshold && echo "TRUE"
TRUE

[tshakalekholoane]

Sorry about that, just edited the comment to run a different command. Can you run this command test -f /etc/systemd/system/bat.service && echo "TRUE"?

TRUE

Please check if the file has any contents by running, less /etc/systemd/system/bat.service.

If it does, then run systemctl enable bat.service and tell me what happens. I have a feeling on Ubuntu you might have to run this with sudo but let me know what happens in the first instance (without sudo) and if everything works after running these.

This is what I am getting after running first command:
[Unit]
Description=Set the battery charging threshold
After=multi-user.target
StartLimitBurst=0

[Service]
Type=oneshot
Restart=on-failure
ExecStart=/bin/bash -c 'echo 91 > /sys/class/power_supply/BAT?/charge_control_end_threshold'

[Install]
WantedBy=multi-user.target

and after running "systemctl enable bat.service" nothing happens. I tried using SUDO also.

[tshakalekholoane]

Nothing happens as in there is no output after running the command or the battery threshold is still not persisting between restarts?

Can you run the following and send me the output? I might have to get Ubuntu installed to try to work this one out.

sudo bat -t 60

sudo bat -p

systemctl status bat.service

And just to make sure, you are running the latest version from the releases page right?

[sjv-afk1]

systemctl status bat.service

Yes I am running the latest release. The following is the output:

Can you check if this fix works?

Not working. Do I need to restart the computer and test it again?

[tshakalekholoane]

I think so. Judging by your output, everything should be working. The threshold level seems to be set to 91 and it should persist between restarts and sleep/suspend but not hibernation.

The only problem seems to have been with the call to set the threshold level which on Ubuntu didn't work because the root user appears to be locked by default but that should not be a problem with this version.

As a last resort, run sudo bat --reset, restart your computer, run sudo bat -t 60. If that does not work, show me the output to that along with the output to cat /sys/class/power_supply/BAT?/charge_control_end_threshold.

If that worked then, run sudo bat -p and show me the output to cat /etc/systemd/system/bat.service and systemctl status bat.service.
