[DEMUG] MacBook Pro dies at 51% battery

[Dick Atlee]

Does anyone have an idea of why a MacBook Pro (OSX 10.4.11) would 
instantly die (power off) when on battery and the battery reaches 51% 
(or at least that is what it is when powered back up).  This is the 
second time this has happened -- which is 100%, since I almost never run 
it on battery and never get down to that level.  It makes it a much less 
versatile machine...

Thanks for any insights.
