Hi
I have a DELL Latitude e7440 ruunning centos 8 where it looks like the battery is not charging.
I have booted, pressed F12 and run the diagnostics which all seem to go through fine. I have also tried to reset the battery by power down, remove battery, power up, power down, replace battery, power up again. But that did not make any difference.
The battery seems to be detected and looks like it is charging, but does not seem to gain any charge.
Running the following command:
Code:$ cat /sys/class/power_supply/BAT0/*

The other tool I found I can use is upower which gives the following:

While searching to try to find ways to troubleshoot battery issues some other tools were mentioned, which I currently do not have on my system:
acpi
tlp-stat
batstat
Does anyone know how I can install any of these tools can be installed on centos 8 ?
