there is an intersting article here about sleep/hibernate modes in real macs
mine was in mode0 , i set it to mode3 but i see no difference
both works... should i notice something?
edit: i forgot the link
You wouldn't see any difference between 0 and 3 unless there is a power failure. 0 suspends to ram, 3 suspends to ram AND disk, if power fails it boots from sleepimage.
