Hi,  I'm Richard a hardware guy at OLPC and I'm in charge of the EC 
code.  I just subscribed to the community-support list so I'm it bit 
cold on this issue.  But I'd like to help.

I've got a few things I'd like you to try.

Step 1 is to see if the EC is booting.  Repeat the remove-all-power step 
. Ie no battery and no external power.  Then try 2 different variations. 
1) just insert the battery
2) just hook up ext power.

In both cases I want you to watch the battery status light when you 
power up the XO.  When the EC boots it briefly flashes the battery light 
yellow.

If that works then see if the EC is continuing to run by inserting a 
battery and then plugging up external power.  You should either see a 
green fully charged battery light or a yellow charging indicator.
