I have a MacBook Pro (Retina, 13-inch, Early 2015) A1502. When replacing the battery I accidentally pulled out the cable shown in the picture. There was a long thin wire connected somewhere too. The long this wire is also shown in the picture. It seems like there is some white corrosion on the left side pins too. The keyboard and mouse no longer work. I’m able to use the computer with a wireless USB keyboard and mouse. What is the best way to repair this problem?
