Preparing to Work Inside the Computer
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. Read and follow applicable instructions in the safety instructions in the System Information Guide that came with the computer. CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface. CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a microprocessor by its edges, not by its pins. NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer. 1. 2. 3. Ensure that the work surface is flat and clean to prevent scratching the computer cover. Save any work in progress and exit all open programs. Turn off the computer and all attached devices.
NOTE: Ensure that the computer is off and not in a power management mode. If you cannot shut down the computer using the computer operating system, press and hold the power button for 4 seconds. 4. 5. 6. If the computer is connected to a docking station, undock it. Disconnect the computer from the electrical outlet. To avoid possible damage to the system board, wait 10 to 20 seconds and then disconnect any attached devices. Disconnect all other external cables from the computer. Remove any installed PC Cards from the PC Card slot. Close the display and turn the computer upside down on a flat work surface.
7. 8. 9.
NOTICE: To avoid damaging the system board, you must remove the main battery before you service the computer. 10. Slide and hold the battery-bay latch release on the bottom of the computer, and then remove the battery from the bay.
11. Remove any installed memory modules, Mini PCI cards, and modules, including a second battery if one is
installed.
12. Remove the hard drive.

Removing the Microprocessor Module
CAUTION: Before performing the following procedures, read the safety instructions in your System Information Guide. NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as the back panel) on the computer. NOTICE: Do not touch the processor die. Press and hold the microprocessor down on the substrate on which the die is mounted while turning the cam screw to prevent intermittent contact between the cam screw and microprocessor. NOTICE: To avoid damage to the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor when turning the cam screw.
1. 1.
Follow the instructions in "Preparing to Work Inside the Computer." Remove the keyboard.
NOTICE: To ensure maximum cooling for the microprocessor, do not touch the heat transfer areas on the microprocessor thermal-cooling assembly. The oils in your skin reduce the heat transfer capability of the thermal pads.
1.
Remove the microprocessor thermal-cooling assembly.
NOTICE: When removing the microprocessor module, pull the module straight up. Be careful not to bend the pins on the microprocessor module. 1. 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.
1 screwdriver (perpendicular to microprocessor) 2 ZIF-socket cam screw 3 ZIF socket 4 pin-1 corner NOTE: The ZIF-socket cam screw secures the microprocessor to the system board. Take note of the arrow on the ZIF-socket cam screw. NOTE: See Mini RSL for microprocessor part numbers. 1. Lift out the microprocessor module.
Installing the Microprocessor Module
NOTICE: Ensure that the cam lock is in the fully open position before seating the microprocessor module. Seating the microprocessor module properly in the ZIF socket does not require force. NOTICE: A microprocessor module that is not properly seated can result in an intermittent connection or permanent damage to the microprocessor and ZIF socket. 1. Align the pin-1 corner of the microprocessor module with the pin-1 corner of the ZIF socket, and insert the microprocessor module.
NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket. NOTICE: You must position the microprocessor module correctly in the ZIF socket to avoid permanent damage to the module and the socket. When the microprocessor module is correctly 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 correctly. 1. Tighten the ZIF socket by turning the cam screw clockwise to secure the microprocessor module to the system board. Replace the other computer parts you removed earlier in this procedure. Update the BIOS using a flash BIOS update program floppy disk or CD. For instructions on how to flash the BIOS, see "Flashing the BIOS."
