I run a toshiba satellite 2805-2503. In an out-of-the-box redhat 7.2 install, my battery life is probably about 3/4 of what it would be on windows. I'm told I can get hard disk spindown functionality if I use the hdparm. (sorry if I got the name wrong.) I haven't done anything about it becuase 95% of the time I run my laptop plugged into the wall with the battery out of it.
