Step 1 :: Side Access Panel

• Press the green release button on top of the side access panel.
• Pull off the side access panel to get inside the computer.
• NOTE: When putting the side access panel back on, make sure that the bottom of the panel lines up with the rail on the bottom, and that the chassis is locked with the green latches.

Step 2 :: Opening the Chassis

• Lay the computer on its side, ensuring that where the side access panel was is facing up.

Step 3

• Unlock the top chassis by moving the two green locking latches upward and outward.
• Using the handle, gently swing the top chassis up and out until it rests firmly on the work surface.

Step 4 :: Processor Module Wire Screw

• CAUTION: When screwing down the wire, be careful not to damage the capacitor next to the screw hole.

Step 5 :: Processor Heatsink Clip

• While pressing down on the top of the processor heatsink clip, use a metal spudger or flathead screwdriver to lift up on the front tab of the clip and release it.
• Remove the clip.

Step 6 :: Processor Heatsink
