Battery applet in plasma says, that there's no battery present in my system. When I open 'kcmshell4 devinfo' and open "Batteries - 42T4861", I see in the right side: "Battery type: unknown. Charge state: nothing" (or something like this, I have russian localization). In the bottom I see: "UDI: /org/freedesktop/UPower/devices/battery_BAT0". So I check whether upower is aware of my battery. See the output of upower here: http://paste.kde.org/496874/ So, the problem is neither in my battery nor in upower. But in solid or solid's upower backend. Restarting computer doesn't help. Reproducible: Always Steps to Reproduce: Look at battery applet. Actual Results: See 'no battery present' Expected Results: Want to see battery state.
Some addition: $ solid-hardware details /org/freedesktop/UPower/devices/battery_BAT0 udi = '/org/freedesktop/UPower/devices/battery_BAT0' parent = '/org/freedesktop/UPower' (string) vendor = 'SANYO' (string) product = '42T4861' (string) description = 'Lithium Ion Battery' (string) Battery.plugged = true (bool) Battery.type = 'UnknownBattery' (0x0) (enum) Battery.chargePercent = 59 (0x3b) (int) Battery.rechargeable = true (bool) Battery.chargeState = 'Discharging' (0x2) (enum) Here I am able to see charge percent.
