Anleitung Zusammenfassung
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 your computer). CAUTION: 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. CAUTION: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw. CAUTION: To help prevent damage to the system board, remove the main battery (see Removing the Battery) before working inside the computer. 1 ZIF socket 2 ZIF-socket cam screw CAUTION: To ensure maximum cooling for the processor, do not touch the heat transfer areas on the processor thermal-cooling assembly. The oils in your skin can reduce the heat transfer capability of the thermal pads. CAUTION: When removing the processor module, pull the module straight up. Be careful not to bend the pins on the processor module. 1. Follow the procedures in Before You Begin. 2. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, then insert the processor module. When the processor module is properly seated, all four corners are aligned at the same height. If one or more corners of the module are higher than the others, the module is not seated properly. 3. Tighten the ZIF socket by turning the cam screw clockwise to secure the processor module to the system board. 4. Replace the processor heat sink (see Replacing the Processor Heat Sink). Back to Contents Page NOTE: If a new processor is installed, you will receive a new thermal-cooling assembly, which will include an affixed thermal pad, or you will receive a new thermal pad along with documentation to illustrate proper installation. NOTE: The pin-1 corner of the processor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket. CAUTION: To avoid damage to the processor, hold the screwdriver perpendicular to the processor when turning the cam screw. CAUTION: Before turning on the computer, replace all screws and ensure that no stray screws remain inside the computer. Failure to do so may result in damage to the computer.

Follow the procedures in Before You Begin. 2. Follow the procedures from step 2 to step 17 in Removing the System Board. 3. Disconnect the fan cable from the connector on the system board. 4. Turn the system board over and in sequential order (indicated on the processor heat sink) loosen the five captive screws that secure the processor heat sink to the system board. 5. Lift the processor heat sink off the system board. WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at WARNING: If you remove the processor heat sink from the computer when the heat sink is hot, do not touch the metal housing of the processor heat sink. CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell™ is not covered by your warranty. 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 your computer). CAUTION: To help prevent damage to the system board, remove the main battery (see Removing the Battery) before working inside the computer. 1 fan cable connector 2 processor heat sink 3 system board NOTE: The location of the screws may change according to the display adapter supported by your computer. Replacing the Processor Heat Sink 1. Follow the procedures in Before You Begin. 2. Align the five captive screws on the processor heat sink with the screw holes on the system board and tighten the screws in sequential order (indicated on the processor heat sink). 3. Turn the system board over and connect the fan cable to the connector on the system board. 4. Follow the procedures from step 5 to step 20 in Replacing the System Board.

If either the processor or heat sink is replaced, use the thermal pad provided in the kit to ensure that thermal conductivity is achieved. NOTE: This procedure assumes that you have already removed the processor heat sink and are ready to replace it. CAUTION: Before turning on the computer, replace all screws and ensure that no stray screws remain inside the computer. Failure to do so may result in damage ...
