[DEMUG] MacBook Pro dies at 51% battery

[James Baranski]

Some of the older laptops occasionally need to have their batteries  
'reset'.
They keep track of the battery usage and charge, and sometimes what  
the laptop thinks
doesn't match the battery.  Look for a 'battery rest' program; it's  
not the same as needing to fully
discharge and then fully charge the battery which the non-Li-ion  
batteries used to need.

I don't know if this applies to the MacBook Pros.
