 > Did you manage to completely discharge the battery in the meanwhile?  If
 a battery is charged to the point it cannot report its status (it has a
 tiny microcontroller in it) to the CPU, the most the machine can do is to
 trickle charge the battery until that microcontroller is again sane,
 before again charging at full speed.

 I've taken the battery out for various lengths of time, between a couple
 minutes to a few hours.  I could leave it overnight if that helps.

 At one point yesterday I think I had the battery completely drained; it
 wouldn't even respond to the power button.  This is after quite a bit of
 playing around.  When I first noticed the trouble yesterday morning the XO
 had shut itself off, leaving the battery around 4% if I recall correctly.
 That prior night it was powered on and plugged into the wall, but not
 really doing anything.

 Last night I left it charging.  The indicator light is still orange, and
 it's gaining about 2 or 3% per hour.  Should I keep charging it all the
 way up? (It's at 39% now, so another day and a half at this rate.) I could
 discharge it all the way down again too.  Something else?
