black screen with continual tone sound
Upon start up the macair gives a tone sound continually - it is not the usual chime - never heard it before. It was brought to a mac store(not Apple store) and I hear they mentioned something about ram, nothing they could do but buy a new machine. I tried zapping PRAM. Does anyone know what this may be? Could it be the ram gone bad, and so a new logic board is required? If so, if I buy a used logic board is it as simple as swapping one out, and the machine is good to go, or will there be additional steps to get the logic board to sync with whatever else(SSD).
Es esta una buena pregunta?
