I would absolutely give this a go. You have a clear goal, to fix the USB port, so you can research the exact process prior to opening the laptop.
Watch some videos, checkout our teardown, commit to the project!
Get your work space ready and have all the parts and tools to hand.
Give yourself a large clean space as organising your disassembled parts and screws is very important, especially with Apple products. They tend to use a variety of different screw sizes.
Get another device setup so you can follow along with the guide of your choice. A mobile phone is ideal as it takes up very little space.
Wear an electrostatic wrist band and ground it to something nearby (remember, bare metal so no painted metal surfaces).
Be patient and take your time. This is a learning experience and you'll want to give yourself enough time to disassemble and reassemble in one session if possible.
Last bit of advice, if you're in there and you feel you can't carry on, don't be afraid to stop and put things back together! Sometimes you have to process what you've learned, research, then come back and take the next step. We all do it and there's no shame in it.
You got this, we believe in you :)
AND we're here to help if you get stuck!
