Hi there, not even sure where to start since there is no topic on internet taking about 4 beeps.
I have this mac doesn't turn on. no image, battery charged fans spins, all common voltages are at place. No water damaged. Never seen board so clean. costumer said best buy swap board for them few months ago.
I press power button, it has 4 peeps then repeats. I have tried RAM just in case.
3 short beeps and 1 little longer, then it repeats.
Any ideas where to start? I tried to plug all the flexes.
