Tools: 3" Needle nose pliers; Phillips #1 Screwdriver

Step 1

• CAUTION: Verify that the console is disconnected from the AC outlet before you begin.
• Flip the console over on its back.
• Take note of your model number, in case replacement parts are needed.

Step 2

• Remove the expansion bay by applying pressure to the small clip on the expansion bay while prying it away from the console.

Step 3

• Locate and remove all four black 12mm Phillips #02 screws from the underside of the console.
• NOTE: Note: Remove the expansion bay to locate the fourth screw

Step 4

• CAUTION: Internal components can be loose. Be careful that they do not fall out when removing the cover.
• Turn the console right side up.
• Remove the top cover by gently lifting the upper portion of the console.

Step 5
