I've been monitoring upower and I think the problem is it is incorrectly
detecting the number of batteries in my laptop. I only have one yet
upower detects 5 power sources. One of them is a DisplayDevice which
normally shows the same amount of battery as my system battery.
Sometimes that drops to 1% or 0%. I've had my laptop plugged in all day
here are two upower -d dumps from within the last 5 minutes. Notice in
the first dump /org/freedesktop/UPower/devices/DisplayDevice has 0%
battery despite the laptop being plugged in. On the second it has the
same engery, energy-full, and percentage as
/org/freedesktop/UPower/devices/battery_BAT0.

Title:
upower abruptly thinks battery has gone to 1% and hibernates
Status in upower package in Ubuntu:
New
Bug description:
Whenever I go on battery after 20-30 minutes upower will very abruptly
think my battery is at 1% and force my laptop to hibernate. This seems
to happen at random times, I've seen it when my battery was reported
to be 90%, 76%, 45%, 25%, etc. If I try to resume Ubuntu locks up
forcing me to hard reset the machine. I suspect this is because upower
thinks my battery is still at 1% when its not. My laptops firmware
correctly reports the battery level and shows that I have plenty of
power remaining. The last few times this happened I kept powertop up
which shows that I do have plenty of power even when upower thinks I
have none. Essentially this makes my laptop unusable on battery.
