Introduction

Use this guide to replace a damaged I/O board ribbon cable.

  • Before proceeding, close your computer and lay it on a soft surface top-side down.

  • Remove the following ten screws:

    • Two 8 mm 5-point Pentalobe screws

    • Eight 2.5 mm 5-point Pentalobe screws

  • The special screwdriver needed to remove the eight 5-point Pentalobe screws can be found here.

I recommend that one of the tools you obtain is a jeweler's loupe that mounts on your glasses. It makes things easier.
