 My laptop shuts down when the battery level gets to about 81%.
 It will not restart without being plugged in again.  It works
 again after being recharged but dies again at about the same level.
 I wrote a script to cat the file
 /sys/devices/platform/olpc-battery.0/power_supply/olpc-battery/uevent
 once a second to watch what was going on.  The results follow:
