[Ti] sleep mode - Battery life

[Kynan Shook]

I agree with that statistic; I too had a Ti/500 before my 17".

The percentage on the battery represents the approximate percent of 
battery power left that is usable by the computer under normal 
operation.  Even after the computer is forced to sleep by lack of 
power, there is enough power to provide at least several hours of sleep 
for you to plug it in before memory is lost.  This is as much a design 
feature as it is the nature of batteries; when they get to very low 
remaining power, the maximum instantaneous power they can supply drops. 
  Since keeping the contents of RAM requires a fairly small amount of 
power, this can be done for much longer, while there might not be 
enough power to provide the display, CPU, etc. with the necessary 
continuous power, not to mention the huge spike of power the hard drive 
needs to spin up.
