immediately when waking up from sleep, my macbook does the usual optical drive spinning noise, but then about 2 seconds of static on the speakers of the macbook. you might not notice it in a loud room. every time, the same static pattern. even if it was asleep for only 10 seconds. the static sound sounds like it comes from the speakers, and it does not matter where the volume is set, the static sounds still happen immediately after wakeup. interestingly, if i have headphones plugged in, the static sound does NOT happen on either the headphones or the built-in speakers. after about 2-3 seconds, the static goes away for good, until it the next wake-up from sleep event. i did notice this thread, but no real answer there: http://forums.macrumors.com/showthread.php?p=3975067 i was just going to ignore it, since it doesn't seem to be a real big problem... but THEN over the holidays, my computer refused to wake up from sleep. it was somehow stuck in sleep mode. brought into the apple store, they tried resetting the PRAM, removing the battery, a bunch of stuff, and eventually determined i needed a new firmware board, which they replaced. i am glad it was under apple care still. but now i am worried, what if this static noise is the sign of an electrical problem on the firmware board, and will this board eventually go bad again? my macbook is the 1st gen intel macbook, about 1 year old... do the newer ones also have this problem? i have recorded the sound, and could upload it in case anyone wants to hear it.
