power consumption after shutdown

[Mikus Grinbergs]

As far as I can tell, the battery in the XO-1 retains its charge 
quite well when taken out of the case.  But in my experience, when I 
specify 'Shutdown' to the software, and close the XO lid after all 
its lights (including 'power') are extinguished -- then when two 
days later I insert the AC adapter into the (still closed) XO, after 
the 'power' light comes on, it goes yellow.  [I've seen this both 
when I was running 'joyride' on the XO, and when I was running 
'staging'.]  I take this to mean that *something* was draining some 
power for the two days the XO was sitting in its "shut down" state.

If I want to prolong the "shelf life electricity" of my shut-down 
XO, do I need to "turn off" some facilities before I click on the 
'Shutdown' entry in the palette of the central icon in Home View ?
