Figure 30. Microprocessor/Heat Sink Removal
CAUTION: The microprocessor SEC cartridge/heat sink assembly can get extremely hot. Be sure that the assembly has had
sufficient time to cool before you touch it.
CAUTION: Use a wrist grounding strap as explained in
NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.
To replace a microprocessor, perform the following steps:
1.
Remove the computer
cover.
2. Locate the microprocessor socket on the system board.
3. Gently pull out the guide-bracket assembly latch, grasp the existing microprocessor/heat sink assembly firmly, and pull straight up to remove
it from the guide bracket assembly.
You must use up to 15 pounds of force to disengage the microprocessor package from the connector. Do not rock the package while
removing it.
4. Slide the new microprocessor package into the guide bracket assembly, with the heat sink toward the front of the computer, and firmly seat
the microprocessor/heat sink assembly.
You must use up to 25 pounds of force to seat the new microprocessor package. Do not rock the package while inserting it into the
connector.
5. Replace the computer cover, and reconnect your computer and peripherals to their power sources and turn them on.
As the system boots, it detects the presence of the new microprocessor and automatically changes the system configuration information in
System Setup.
NOTE:After you remove and replace the cover, the chassis intrusion detector will cause the following message to be displayed at
the next system start-up
ALERT! Cover was previously removed.
6. Enter System Setup, and confirm that the top line in the system data area correctly identifies the installed microprocessor.
7. While in System Setup, reset the chassis intrusion detector by pressing the left- or right-arrow key to select Reset, and then choose
Enabled, Enabled-Silent, or Disabled (see your User's Guide for instructions).
8. Run the Dell Diagnostics to verify that the new microprocessor is operating correctly.
