Removing the Microprocessor Module
1. Remove the hard drive.
2. Remove the keyboard.
3. Remove the microprocessor thermal cooling assembly.
4. 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 microprocessor to the system board. Take note of the arrow on the ZIF-socket cam screw.
5. Use a microprocessor extraction tool to remove the microprocessor module.
Replacing the Microprocessor Module
NOTICE: Disconnect the computer and any attached devices from electrical outlets, and remove any installed batteries.
NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or by touching an unpainted metal surface on the computer.
NOTICE: Read "Preparing to Work Inside the Computer" before performing the following procedure.
NOTICE: When replacing the microprocessor, to ensure proper thermal operation, always install a new thermal cooling assembly that is compatible with
the new microprocessor.
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.

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

1. Align the pin-1 corner of the microprocessor module with the pin-1 corner of the ZIF socket, and insert the microprocessor module.
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.
2. Tighten the ZIF socket by turning the cam screw clockwise to secure the microprocessor module to the system board.
3. Install a new microprocessor thermal cooling assembly.
4. Update the BIOS using a flash BIOS update program CD.
Flashing the BIOS
To update the BIOS:
1. Ensure that the AC adapter is plugged into an electrical outlet and that the main battery is installed in the battery bay.
2. Turnonthecomputer,andwhentheDell™logoappears,press immediately.
If you wait too long and the Windows®logo appears, continue to wait until you see the Windows desktop. Then shut down your computer and try
again.
3. When the boot device list appears, highlight CD/DVD/CD-RW drive and press .
4. Insert the flash BIOS update CD, and reboot the computer.
The computer boots, updates the BIOS, and reboots.
5. Remove the flash BIOS update CD.

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.
HINT: 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.
NOTICE: Hold the microprocessor down while turning the cam screw to prevent intermittent contact between the cam screw and microprocessor (see
"Removing the Microprocessor Module").
NOTICE: When replacing the microprocessor, to ensure proper thermal operation, always install a new thermal cooling assembly that is compatible with
the new microprocessor.

When to Use the Dell Diagnostics
Features of the Dell Diagnostics
Starting the Dell Diagnostics
Advanced Testing
Confirming the System Configuration Information
When to Use the Dell Diagnostics
Whenever a major component or device in your computer does not function properly, you may have a component failure. If you are experiencing a problem
with your computer, perform the checks in "Solving Problems" and run the Dell Diagnostics before you call Dell for technical assistance. Running the Dell
Diagnostics may help you to resolve the problem yourself quickly without having to contact Dell for assistance.
If you are experienced with computers and know what component(s) you need to test, simply select the appropriate diagnostic test group(s) or subtest(s). If
you are unsure about how to begin diagnosing a problem, see "Starting the Dell Diagnostics" and "Advanced Testing."
Features of the Dell Diagnostics
The Dell Diagnostics helps you check your computer's hardware without any additional equipment and without destroying any data. By using the diagnostics,
you can have confidence in your computer's operation. And if you find a problem you cannot solve by yourself, the diagnostic tests can provide you with
important information you will need when talking to Dell's service and support personnel.
The diagnostic test groups or subtests also have these helpful features:
lOptions that let you perform quick checks or extensive tests on one or all devices
lAn option that allows you to choose the number of times a test group or subtest is repeated
lThe ability to display test results or to save them in a file
lOptions to temporarily suspend testing if an error is detected, or to terminate testing when an adjustable error limit is reached
lExtensive online Help screens that describe the tests and how to run them
lStatus messages that inform you whether test groups or subtests were completed successfully
lError messages that appear if any problems are detected
Starting the Dell Diagnostics
The Dell Diagnostics are located on a hidden Diagnostic utility partition on your hard drive.
1. Turn off the computer.
2. If the computer is connected to a docking device (docked), undock it. See the documentation that came with the docking device for instructions.
3. Connect the computer to an electrical outlet.
4. Press and hold down the DellAccessDirect™button while you turn on the computer.
The computer begins to run the Pre-boot System Assessment, a series of embedded diagnostics that perform initial testing on your system board,
keyboard, hard drive, and display.
lDuring the assessment, answer any questions that appear.
lIf a component failure is detected, the computer stops and beeps. To stop the assessment and reboot to the operating system, press ; to
continue to the next test, press ; to retest the component that failed, press .
lIf failures are detected during the Pre-boot System Assessment, write down the error code(s) and then contact Dell before continuing on to the
Dell Diagnostics. See your Owner's Manual for contact information.
lIf you receive a message stating that no Diagnostics utility partition has been found, follow the instructions on the screen to run the Dell
