Macbook A1990 is a great machine but this one spent over 3 months with another tech workshop only to come back still dead and various items on the board changed. While I did repair this machine a few months ago to get it up and running again I missed the fact that the rear-most left hand side USB-C port wasn't working still; as such I organised with the owner to return it when they were ready so that I could subsequently fix up the faulty port, and this is what I found... 00:00 Welcome 00:30 Disassembly 05:45 Testing the port 07:30 Testing the logic board 10:00 Removing the CD3215 14:10 Installing replacement 17:15 machine working, time to rebuild it 25:10 to skip the machine rebuild
