• The following step covers the hardest part to get inside this computer. Take a deep breath and think happy thoughts.
• Grasp the back corners of the upper case and pull up, disengaging hidden tabs on the sides. Do not pull the upper case off yet; you still need to free tabs in the front of the case.
• The seam is beneath the plastic molding on the upper case.

• There is one latch that stops you from pulling the upper case right off, located on the left side of the optical drive slit. To free the upper case, you will be pulling a thin metal latch toward you, freeing it from the clasp holding it in place.
• Pry up the left side of the upper case slightly with your hand and wedge a spudger into the seam between the upper case and lower case.
• Leave the tool in place applying pressure to the upper case for the next step.

• Place enough pressure on the upper case to allow you to slide a tool just within the seam between upper case and lower case as shown in the picture. A dentist's hook, push pin, or similar tool will work.
• Do not yank the upper case off as soon as you free the clasp. The case is attached to the logic board via two ribbon cables.
• Delicately slip the tip of your tool behind the silver metal latch and pull it forward while pulling up on the case. This may take some effort.
