My theory has hole. I realized today that 0% never happens. The battery
system on XO-4 only marks the battery as 0% _after_ the critical shutdown
voltage is reached (which powers off the laptop). powerd won't ever see a
0%.
The problem also seems intermittent since the last set of logs sent from
quanta appear normal modulo things that can be attributed to file copy
problems (1 missing file).
