This is the third part of MacBook repairing videos in which we’ll continue analyzing Apple laptop schematics. And on this video you’ll see how the very important voltage, PP3_V42_G3H and SMC_RESET_L signal are generated and we’ll analyze them as they are so important in repairing MacBook devices. And in case the voltage and the signal are absent, a lot of blocks on MacBook devices won’t work.
Hope you enjoy MacBook repairing series
