Actually, the event that I get when adding or removing the AC adapter is
"battery BAT0 00000080 00000001".  The event for removing the battery is
"battery BAT0 00000081 00000000".  (for some reason I get duplicate
events when (un-)plugging the AC adapter; you may want to check that
your handler takes appropriate action for redundant events)

I am not sure if this is the expected/desired behavior, perhaps someone
with more experience with ThinkPad internals can chime in here... ;)
I just use a script to handle all battery events that checks the state
of the AC adapter and acts accordingly.

Hope it helps,
Kevin

P.S.  There are good example scripts on the ThinkWiki
(http://www.thinkwiki.org/wiki/Category:Scripts ), and distributed with
Laptop Mode Tools
(http://www.xs4all.nl/~bsamwel/laptop_mode/tools/index.html )
