i have a 15 ti pb g4. i was wondering if it was possible to get the apple logo that lights up when the laptop is on to pulse when the pb is in sleep mode instead of the sleep light. also, do you know what makes the lights pulse when in sleep? is it a hardware switch of some sort or a software command that makes it pulse. i have seen the mods to make the apple logo colorful, but none that make it pulse while in sleep mode. thanks for any help you can provide. if you can only point me in the right direction that would be fine as well.
