USB C connector works one side only
I have a problem similar to this one - iPhone 5 only charging on one side?, but with MacBook 12” 2017. One morning I found it completely dead, even though it was plugged all night and I do not usually discharge more than 80% anyway.
After spending a couple of hours attempting to resurrect the device, it finally started charging. When I opened the lid the battery was completely dead, i.e. 0%. I charged it completely and then decided to do SMC reset. I had bad luck again. After shutdown it won’t boot again, even though the device was fully charged.
After another hour of pressing various buttons it finally booted. Just in case, I did SMC and NVRAM reset, but after final reboot it stopped charging again. Another useless hour and I realized that it’s USB-C port works only one side. I.e., similar to micro USB connector, I need to plug devices in with one specific side. If I rotate it 180 degrees it will not work. Everything works fine - USB devices like flash reader, Display Port, HDMI, charging, but only on one side. If I turn it 180 degrees, it does not connect.
I tried to look inside the connector and it looks pretty normal - no bent pins or anything I could see. I am thinking about cleaning the pins with some solvent, but not sure which one to use. Could you suggest if this can be a hardware, i.e. - controller issue or more likely an oxidized pin?
Ist dies eine gute Frage?
