Re MacBook Pro

Customer Question

Re: MacBook Pro:
One (of 2) USB port became dead, virtually overnight. No known reason. Just stopped working.
Is this likely to require a hardware repair please?

Hi, try these two steps and see if it wakes up.

If not, then it needs to be evaluated by a tech.

Reset SMC:
Turn off Mac
Remove power cord AND battery
wait about 1 minute.
Press the power button and release.
Replace battery and power adaptor
Turn on Mac. It may take 2 presses of the power button to start.

Reset PRAM:
as soon as it starts, hold down the following keys:

Keep them down until the Mac chimes 3 times and then release them and let it boot normally.

Test the port.

Hi Mike.


Thanks for that.


I have followed your instructions to the word - but unfortunately, the port STILL remains dead.

(Note: these were also the same tips that I had previously sourced from the internet & tried without success).

Is this indicating a hardware failure, as I had suspected?


Cheers, Jon.

Yes, unfortunately it does. It may be a bent pin in the connector or a bad chip on the logic board that controls that port.

Not much else but take it to a shop and have it evaluated.

Thanks anyway.
