Step 7 — DVD Drive
Before continuing, place a soft cloth on your work surface to rest the computer on. Turn the G4 over, making sure the DVD drive doesn't fall out.
Carefully peel the adhesive strip away from the DVD drive. The plastic dust shield covering the DVD drive is easily damaged. Try to start at the four corners and work toward the center.
Step 8
Bend the silver metal EMI clip so that it is vertical. This part may fall out after removing the DVD drive.
The EMI clip is not essential for reassembling the computer. If the clip falls out, don't worry about putting it back in.
Step 9
Turn the G4 over.
Disconnect both orange ribbon cables from the logic board using a spudger or the tip of your finger.
