No charge, no light on charger, tested two chargers and replaced DC-in
Hello,
a few days ago my Mac started to randomly stop charging depending on how the cable was positioned. The charger was beat up pretty bad so I ordered the same charger (used official Apple charger) off Ebay. This second charger never worked, while the old one was still charging sometimes. Since then both chargers have stopped working.
After all this I ordered a replacement DC-in board since the contacts on the original one looked burnt. Still no charge, no light. Also tried measuring voltage and amps while the PC was open on the DC-in board but my multimeter showed no readings.
This is the DC-in board I bought
I'm currently talking with the Ebay seller to get a replacement charger but at the moment I'm not very optimistic... could the middle data rail be damaged on the mainboard, meaning no communication between charger and laptop = no charge? Or possibly a power rail? How would I go about diagnosing this? Seeing as no power enters the machine I hope both chargers were done for and the replacement works, otherwise this repair is out of my league.
Old charger:
Update 2023/08/13:
Managed to get the old charger to connect again and it showed a green light. After a while (10-15min) the mac still didn't want to start, just showing an empty red battery but indicating that it was charging.
Now I decided to reset the SMC, since that was always suggestion number one to fix macs charging weirdly. Now the indicator on the charger is glowing amber, but pressing the power button does nothing. Charging brick is also not heating up at all. After about 20-30 minutes I disconnected the charger and now both chargers don't work again...
Is dit een goede vraag?
