 SN SHF7250050D, A25

 At different times during testing over the last week, both of these
 machines have exhibited a mysterious shut down.

 In both cases the laptops were connected to a power adapter and I was
 toggling between neighborhood mesh screen and XO home screen. The screen
 just goes completely blank, the power led went off.

 On the A20 (where this just happened to me), the battery adapter led is
 still on so I *think* the battery is good. I pressed the power button and
 the unit began to power up and after it got into the icons along the top,
 it died again.

 I waited about 10 minutes and clicked on the power button again... this
 time it got all the way to most of the text scrolling, but still didn't
 quite get to sugar, and then died.

 I think this has to be a battery/ec problem. Richard had looked at A25
 briefly when this happened the first time, but it wasn't in the bad state.
 Maybe the unit is only charging when it isn't on or something...

 Assigning to Richard.
