Installing the Processor
1. Unpack the new processor.
CAUTION: The processor and heat sink can become extremely hot. Be sure the processor has had sufficient time to cool before handling.
NOTICE: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper
thermal conditions.
NOTE: When removing the heat sink, the possibility exists that the processor might adhere to the heat sink and be removed from the socket. It is
recommended that you remove the heat sink while the processor is still warm.
NOTICE: Be careful not to bend any of the pins when removing the processor. Bending the pins can permanently damage the processor.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as
authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not
authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
