I have one that I've run off battery before for a while. As long as you're not running the CD/DVD drive, or doing a lot of heavy computation, or banging the hard disk, it'll do over 3 hours with no sweat; 4 is pushing it a bit, and 5 is probably unrealistic.

Hi, I am thinking of buying a 12' PowerBook, as a second computer to a generic PC (right now I have an old Toshiba Satellite). I need a PC to run applications Apple doesn't support (AutoCAD and MS Access). Apart from desktop computer I need a notebook for occassional portability. I never had a Mac and am curious (= I really want to try a Mac instead of say a PC notebook with external monitor and docking station) - I like Powerbook's compact size, and 5 hrs battery life - this is I suppose most important as i often minute meetings that last about 4 hrs or more. What's your experience with the battery on PowerBooks? Thank you, Anna

I don't think you'll really get 5 hours of typing.

I'd recommend a Pismo PowerBook G3 (this would be used), which will hold two batteries. I routinely got 7 hours of run time from mine.

On the other hand, if you have resting point during your meetings, just get two batteries. One wonderful thing about the PowerBooks with OS X is that they will go to sleep INSTANTLY when you close them, and wake up as fast as you can open them up (no 30 second sleep and 45 second wakeup). While they are asleep you can swap batteries - a complete sleep-change battery- wake cycle for my 17" PowerBook takes about 20 seconds total.

The instant sleep and wake of the PowerBook is the single greatest thing about them to me. It totally changes the way I work with a laptop.

This didn't work on my 12-inch PowerBook when I tried it. The new battery went in, and the system started from ground zero.

KeS Kevin, thank you. Second hand market is not so great in Australia (comparing to US), and if i get second hand Pismo, I'd probably had to buy new bateries anyway. But I like the idea of PowerBook with 2 batteries - didn't realise swapping was that simple, thanks again, Anna (remove me before replying)

Hmm, nice catch! Apparently the 12" PowerBooks don't support this:

while it is supported on the 15" and 17" PowerBooks:

(and was on the G3 Pismo as well). Important safety tip! Sorry for the misinformation, Jay. :(

Shame, too...guess they didn't have room for the internal battery necessary to do this.

Sorry for the misinformation, Jay. :(

Don't be on my account; I discovered this the hard way a long time ago.
