Removing the Processor

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface, such as a connector on the back of the computer.

NOTICE: To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to apply slight pressure to the center of the processor while turning the cam screw.

NOTICE: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.

1. Follow the instructions in Before You Begin.
   
   
2. Remove any installed media bay device (see Media Bay Devices).
   
   
3. Remove the hinge cover (see Hinge Cover).
   
   
4. Remove the keyboard (see Removing the Keyboard).
   
   
5. Remove the palm rest (see Palm Rest).
   
   
6. Remove the processor thermal-cooling assembly (see Removing the Processor Thermal-Cooling Assembly).
   
   

NOTICE: When removing the processor, pull it straight up. Be careful not to bend the pins on the processor.

7. To loosen the ZIF socket, use a small, flat-blade screwdriver and rotate the ZIF-socket cam screw counterclockwise until it comes to the cam stop.
   
   

The ZIF-socket cam screw secures the processor to the system board. Take note of the arrow on the ZIF-socket cam screw.

Installing the Processor

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface, such as a connector on the back of the computer.

NOTICE: Ensure that the cam lock is in the fully open position before seating the processor. Seating the processor properly in the ZIF socket does not require force.

NOTICE: A processor that is not properly seated can result in an intermittent connection or permanent damage to the processor and ZIF socket.

1. Align the pin-1 corner of the processor so that it points to the triangle on the system board, and insert the processor into the ZIF socket.
   
   

When the processor is correctly seated, all four corners are aligned at the same height. If one or more corners of the processor are higher than the others, the processor is not seated correctly.

NOTICE: To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to apply slight pressure to the center of the processor while turning the cam screw.

2. Tighten the ZIF socket by turning the cam screw clockwise to secure the processor to the system board.
   
   
3. Peel the backing off the thermal cooling pad and adhere the pad to the portion of the thermal-cooling assembly that covers the processor.
   
   
4. Replace the processor thermal-cooling assembly (see Processor Thermal-Cooling Assembly).
   
   
5. Replace the palm rest (see Palm Rest).
   
   

NOTE: If necessary, ensure that you reconnect the coin-cell battery (see Coin-Cell Battery) before you replace the keyboard.

6. Replace the keyboard (see Replacing the Keyboard).
   
   
7. Replace the hinge cover (see Hinge Cover).
   
   
8. Replace the media bay device (see Media Bay Devices).
   
   
9. Replace the battery.
   
   
10. Update the BIOS using a flash BIOS-update program CD (see Flashing the BIOS).
