I have a MacBook Air 13 820-3437 board that had 3 beep ram error. After reflow of the ram , now cpu gets hot but doesn't chime. When I plus in charger to board it doesn't do common on/off cycles before chime but it start immediately with full speed fan. Cpu gets hot but no chime? What could be? What should I measure in this case? Thanks you in advance
