It would normally mean the charge was low, but is being triggered
incorrectly.  It should be fixed in the firmware version that we 
just released, Q2B81.

Yes, cat /sys/class/battery/psu_0/{capacity_percentage,status}.

Please upgrade to the Q2B81 firmware -- as well as fixing the battery
problem, it works around a CPU bug that was causing a 30% performance 
hit across the board!

(Anyone else with a B2 should upgrade too.)

Thanks,
