[Ti] BookEndz not recognizing being plugged in

[Read Weaver]

I've got a BookEndz docking station for my TiBook, and sometimes when  
I insert my computer it doesn't recognize that it's plugged in, and  
instead runs on battery. (All the other connections I use [USB,  
video, Firewire, ethernet] are fine.) While it's certainly possible  
that it's just a loose connection in the docking station I'm  
wondering if anyone else has run into this with another answer.

It seems like it happens if I last ran the computer on battery before  
re-docking it; if I run the computer plugged in, then shut it down,  
then unplug the computer, then insert it into the dock, then turn it  
on, it knows that's it's plugged in, but if I run it on battery, turn  
it off, dock it, and turn it on, it thinks it's still on battery.  
(But before I try each of those over and over I thought I'd see if  
anyone here has experience with it.)

(This sounds kinda nuts to me, it's just a straight through  
connection from the power cord through the dock to the computer--but  
it actually doesn't seem to be random.)
