Hi, so I accidentally spilled some coffee in my backpack (coffee top wasn’t screwed on right), which dribbled down then got into the USB/charge port of my 2015 MacBook. I tried, in a panic and idiotically, to charge immediately after, without drying out the port completely (but will I really know if it’s dry?), and of course it won’t charge. Have I done lasting damage? Or can I try the rice-in-the-bag trick later and cross my fingers? Is there something else I should do? MacBook is working fine, but I am worried that I won’t be able to charge it again, ever!
Rice as a desiccant is an old wives tale (Absolute BS!!!) http://www.riceisfordinner.com Open it up ASAP. Disconnect the battery. Blot up any liquid you can find. Take the logic board out and inspect it. You have probably fried the USB-C port. Let it air dry for a couple of days. Plan on replacing it: MacBook 12" Retina (Early 2015) USB-C Port Here’s how: Retina MacBook 2015 USB-C Port Replacement
TRUE This happened to my mom on September 30 2018 at 8:30 pm she is still on it currently to try to get it to work but it happened on her phone and for my brother to watch some videos on her phone and he is only 2 so I will probably be up all night with him it works though it just won’t charge and the bad thing is it currently is on 6% so you will have to let it air dry for 3 days.
