The apple service experts in my country are stumped. Can anyone here help?

    I have a 2016 MacBook Pro with touchbar. Suddenly the top left USB C port stopped working after I booted up the laptop after not using it for a few days (from 0% charge). The device passed the AST2/MRI test and they reset the MLB and it started working. I was given the laptop and the same issue started again with another USB C port on the right side (the left side was working). After a reset, it started working again.

    Now the same issue reoccured for the third time. According to them there is no hardware issue, but I Can't keep on giving it them for a software reset. Does anyone know whats wrong and what apple policy is (its still under warranty) in terms of replacing laptops that have no apparent hardware malfunctions but have weird issues that require repeated advanced software intervention?

    My country has no official apple stores and geniuses etc but I think that the replacement policy is the same for all countries.

    Thanks so much!

    There's no resets available to that model so far as I know other than:

    PRAM reset - turn on machine, hold down Command-Option-P-R, let machine reboot 3X to make sure it sticks, you can tell if you had system volume set to a low level and the system bong goes back to normal

    SMC reset - turn on machine, hold down Power/TouchID and Shift-Control-Option for 10 seconds, then release all keys and hit the Power button

    There's an Apple test for the power charger that forces the geniuses to plug the power cord in and flip it to make sure the cord and port are working right, not sure if that checks for USB though.

    As others have said contact Apple directly

    I have no idea how the circuitry etc works to prevent multiport charging ie plug in one or more chargers and only one will be used but the problem could lie there is my best guess as it would disable the least charge port it almost seems your MBP is doing this
