There is also battery reset 2.0 for the Wallstreets and some Clamshell iBooks
http://lowendmac.com/rivera/06/apple-battery-reset.html
if Johns suggestion about a PMU reset doesn't work.
I did this on mine after the battery got down to only allowing 15 mins use and
this utility got me back to using the Wally for an hour and a half on battery
power.
Still not 3+hrs use like a new battery but way more acceptable than 15mins for
sure.
