Changing Batteries on PowerBook G4 (Aluminum)

Message #1 - Posted 2005/05/11 - Nelson Lu

At the advise of my local "Genius," I've bought a new battery for my PowerBook G4 (aluminum) (just upgraded to Tiger), but I forgot to ask him whether I can/should change batteries while the computer is asleep as opposed to shut down. The computer manual implies that that is OK, but at the same time in the directions for changing batteries gave the direction to shut down the computer.

Also, is it better to have the computer plugged into the outlet at the time of the change of battery or not, or does it matter?

Any information/opinion on this would be appreciated.

AFAIK you can swap out batteries when the machine is asleep: http://docs.info.apple.com/article.html?artnum=88059

Note that this article applies to the 15" and 17" PowerBook models, not to the 12" model. The 12" model does not have an internal backup battery and will shutdown in sleep mode as soon as you remove the main battery if it is not connected to external power.

I decided to go ahead and try it, so I changed the battery while the computer was asleep and plugged in; it went off without a hitch. Thanks for all who gave information on the matter.
