Hi all, I feel a little newbie (well, I am to the laptop world anyway :-) to ask this question : - Do you shutdown your iBook often or only when moving it and putting it to sleep for all other occasions ? - How does sleep affects the battery ? While on battery, would it be better to shutdown the iBook ? My previous G3 was making airplane-class noise, even while sleeping, but my new iBook G4 makes so little noise I always think it's not powered on :-) I found out how easy it is to put to sleep my iBook (close it !)... would it be a good strategy to shutdown it only when moving it to another place ? Thanks for your precious insights :-) Alex :-)
