Debian Testing - up to date.
Battery charging configuration: In the BIOS I have this set to "custom" and have set the limits as 50%-65%. The result of this is that at about 64% capacity, the charging system stops charging the battery and the laptop essentially runs off the PSU. I think this is great for battery longevity. I wonder what the consequences of this are on operation.
Here is what I see reported:
Code: Select all
hbarta@rocinante:~$ cat /sys/class/power_supply/BAT0/status
Unknown
hbarta@rocinante:~$ cat /sys/class/power_supply/BAT0/capacity
64
hbarta@rocinante:~$
If I were coding something that operated differently on A/C vs. battery, I'd only choose the A/C mode only when the battery/charging status definitely indicated A/C power. Other status (including "unknown") would warrant operating in 'on battery' mode.
Is there an easy fix for this? A not so easy fix? I suppose it starts with kernel or modules that identify the battery/charging status and percolates up through the desktop environment that displays battery condition and perhaps makes decisions based on that condition. At present the Gnome battery indicator shows "Estimating..." for battery status. If I open "Power Settings" it provides the charge level and indicates "charging" while contents of /sys/class/power_supply/BAT0/status are "Unknown".
Thanks!
