output of ls -Flavh /sys/class/power_supply/BAT0/
SUMMARY
The option to set the battery charge limit does not show up on my Asus
Vivobook laptop.
I suspect that the MR:
"Support new charge_control_*_threshold" -
https://invent.kde.org/plasma/powerdevil/-/merge_requests/70)"
Did not account for the case where "charge_control_start_threshold" does not
exist, as outlined in this comment:
https://invent.kde.org/plasma/powerdevil/-/merge_requests/22#note_110418
STEPS TO REPRODUCE
1. In the terminal run "systemsettings"
2. Navigate to Power Management > Advanced Power Settings
OBSERVED RESULT
The charged limit settings are not shown.
The terminal logs:
Warning from helper: Failed to open
"/sys/class/power_supply/BAT0/charge_control_start_threshold" for reading

Warning from helper: Failed to open

org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds

EXPECTED RESULT
The charge limit settings should be supported and shown.
