Hi All,
Long time lurker first time poster!
I've got a Macbook logic board 820-3536-05 that I'm trying to repair, I believe it had a knock off charger connected. When I opened it up the DC in fuse on the logic board (F7005) had been blown and a unknown SOT323 type package was fried on the DC in board (photo attached).
I have replaced F7005 and the DC-in board (820-2584-A).
If I power the laptop using a salvaged magsafe connected attached to a bench PSU everything works great, the laptop is fully functional. LED goes green then amber as it should and the laptops takes a charge.
However it will not take power from an official Apple charger. I see the 3V for 1 second which is supposed to activate the charger, followed by a momentary 16-17V but then the charger cuts out almost immediately (photo attached).
Has anyone any suggestions?
Many thanks in advance!
