> Did you do this while the led was flashing?
No. Forget the 0 error. It was after removing and inserting the battery.
> What state is the battery in when you plug it up?
Almost fully charged.
> Please attach your power log(s).

> Also if you can duplicate this easily then in a terminal please run
olpc-pwr-log before you do your test and just let it log. olpc-pwr-log
records most of the same thing as what is in your power log but it logs
every 20 seconds.
The sequence leading to flashing red has a few more steps than described
originally. Start the sound application and leave it running. Unplug
external power. Eventually the system shuts down automatically but I have
yet to witness the automatic shutdown. Later, when finding the system
down, plug in external power and restart it. Then in some cases the red
light will be flashing. To stop the flashing red, shut down, cycle the
battery and start up. With external power connected the light will change
from yellow to green after 5-10 minutes.

Isn't logging suspended when the screen goes black after an idle time.
I don't know what to call the state. Hibernation, suspended,
quiescent? Is there a time stamp encoded in the log?
Wouldn't automatic shutdown before the red light be preferable
to shutdown after the flashing red has begun?
