 XO-1.5 SN SHC005007B7  (C2)

 When I reboot with "bye" or turn on with the power button, this unit has a
 high probability of flashing the red battery LED twice.  The complete
 cycle is:
 {{{
 Green battery LED on for about 2 seconds
 Green power button LED flashes
 Red battery LED flashes twice
 }}}
 The cycle repeats several times, then the system eventually starts OFW.
 The repetition count is sometimes as few as one, and sometimes quite a
 substantial number.  Sometimes it will get into a mode of seemingly
 infinite repetition of the fail cycle, and you can kick it into booting by
 briefly removing the AC (with battery attached), then reinserting AC after
 it boots to OFW.

 I tried all combinations of AC only, battery only, and AC+battery.  I got
 at least some red flash sequences in all of those cases.

 The AC adapter is the white one that was supplied with the unit (from the
 Quanta box).

 I have two C2 units.  The other one doesn't exhibit the problem.  I tried
 swapping the AC adapters, and the problem stayed with the XO, it didn't
 follow the adapter.  Swapped batteries; problem stayed with XO.
