[Bug 865980] New: Dual Battery Laptop: Bat1 is drained before Bat0 and system suspends if Bat1 is empty

The system thus only has half of the possible battery life! Reproducible: Always Steps to Reproduce: 1. Use Lenovo T440s with two batteries in battery mode 2. Wait for BAT1 to drain before BAT0 3. Actual Results: System uses BAT1 before BAT0. Thus, "Battery critical" warning and action occurs it BAT1 is empty, although BAT0 is still fully charged Expected Results: System should drain BAT0 before BAT1. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

From this point of view it does seem to be a problem of the KDE

BAT1 is the optional and removable battery (rear). Logically it is reasonable to drain BAT1 first, as this leaves the laptop running when changing or removing the optional battery (as BAT0 is still charged). powermanagement, which only considers BAT1 for its runtime calculations and battery state warning. I am thus changing the Component to KDE. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

KDE only grabs the "time-to-empty" details from upower per battery. Unfortunately, upower 0.9.x only provides "time-to-empty" for the particular battery in use, but not for ALL power sources combines, see: mo-thinkpad01:~ # upower -i /org/freedesktop/UPower/devices/battery_BAT0 .. battery <NO "time to empty" available as battery is not discharged> mo-thinkpad01:~ # upower -i /org/freedesktop/UPower/devices/battery_BAT1 .. battery As a result, KDE is unable to get a combined battery lifetime. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
