820-01958 only 5V no power
Hi everyone, these days are hellish, there seems to be a general death of MacBooks, the one I'm analyzing today always has 5V on the PP20V line and nothing else, no liquid, no shorts on most of the lines I've analysed.- modesto1993

MacBook Air with diode burnt
Good morning everyone, I've been dealing with a MacBook Air 820-01521 for two days that suddenly stopped working. After much research I found damaged D3321 and D3320. I replaced them but the computer won't turn on. I have 5V on PP20V_USBC and the CPU at 0.90V stable. But no sign of life.- modesto1993
