Hi, So as many may know, the definition of 'sleep' for older desktop computers was the HDs spinning down and the monitor switching off, with system fans still running. Later on, 'sleep' was actually SLEEP, where the system is completely silent with all extra things off, freezing the computer's state in time (I believe on the RAM). That said, Apple's desktop computers saw real 'sleep' by 1999 with the slot-loading iMac G3s and PowerMac G4 (graphite). I have here my B&W PowerMac G3, which is the base 300Mhz model, released in 1999 of course. This was the last desktop Mac before they all had switched to smarter sleep systems. I just upgraded mine from OS9 to Panther, hoping that it would do something to the firmware and let it go into full hibernation, but the fans still continue to run after I put it to sleep. Is there such thing as a firmware update for this or will this PowerMac never have the function to fully sleep? I love old computers, but the fact that desktops had to have their fans still running during sleep really sucked.
