Re: Re: Re: Re: PB Battery Life
If you want full battery life that they advertise you'll have to do a few things. #1 run OS9 instead of X. X lessens the life by about a half an hour. Why I don't know.
#2 Run your screen at it's dimmest.
#3 Scale the processor speed back in energy saver. On my 400mhz PB I did an AE test at the slower processor speed. It rendered the same speed as a 604e running 300mhz. I had just gotten my PB at the time and wanted to see how fast it was. I was quite irritated until I realized it was using the slow processor speed because it was on battery!
With all those things done the longest estimate my PB EVER showed me in the battery life clock was just over 4 hours. In OSX, running normally with a full screen I get 2 hours. When it gets down to a few minutes I can dim the screen and grab an extra10-20 minutes.
You can bet that when Apple did the tests to get the 5 hour result they did all the above and probably some other trick like turn off all the extensions, make the desktop black (there's a thought!) and then lie a little.

I know how you feel. My 550 MHz AMD-K6-II barely gets over an hour of light use...less than 20 minutes at full CPU! So yeah, funny how technology changes...
Anyway, has anyone ever put a battery intended for a newer powerbook into an older, slower one? I'd imagine the battery life would go over the 5 hours apple expects...
