Hi,
I seemed to have caused a
 XO power glitch reboot at;

 storyjamunicef.googlepages.com

 at which Henry suggested [after
 examining /var/logs] that you may
 wish to know how I did so.

 Reaching across the table for
 the charger plug in the XO
 that was being charging I not
 very smoothly attempted to remove
 the plug NOT BY twisting in a
 rotating manner BUT BY rolling
 my thumb past the plug grippy
 area between that and the side
 of the XO.  Not a great
 technique especially considering
 that relaxing the pull of the
 plug seemed to result in the XO
 screen powering back up indicating
the progress of a reboot.   So I left
the plub in the XO until after the
reboot finished loading suger
before removing it completely.
BY then I'd simply grabbed the
opposite side of the OX and
pulled the plug in an adult as
possible manner.

 Could sleep mode have been entered just as
 I was attempting to remove the plug?
Perhaps the logs would have indicated that.

Is there some compelling reason
why y'all haven't built your
own Power Management Unit ICs?

Forget intel inside but like
Dolby labs does with audio
fidelity and recently Faroudja <http://en.wikipedia.org/wiki/Faroudja>
 does with video fidelity
OLPC really should do for
battery fidelity; letting
 users forget about the care
   and feeding of XO and any
 other licensed laptop battery
 and just USE IT with ups chip(s)
managing the charging and
giga-ohm floating while under
mains current power. This was
mentioned by Amory Lovins <http://www.rmi.org/> over a
 decade ago during a talk at which
he pulled the plug on his IBMish
looking laptop exclaiming,
"built in UPS" or some such
verbiage which may be true for
expensive IBM gear BUT even
insanely expensive Apple buries
the notice of "leaving the
MACtop on mains power severely
shortens battery life".
So now I have XO rather than
another MAC battery :)  But
 12 hours of use - not yet.

  Also FYIs -
 Dwalt has a  NANO™-phosphate
 lithium ion battery circular
saw<http://www.dewalt.com/us/products/tool_detail.asp?productID=17782>.

Surly the world needs CHIP-ups
inside to keep those batteries
properly topped up and not
applying life shortening
 over charges.
Rigid tools sells drill
with free battery for life.
