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.
1. Before upgrading your system, download the latest system BIOS version from support.dell.com and follow the
instructions included in the compressed download file to install the update on your system.
NOTE: You can update the system BIOS using the Lifecycle Controller.
2. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet. When
disconnected from the power source, press and hold the power button for three seconds to fully drain the system
of stored power prior to removing the cover.

WARNING: The heat sink and processor are hot to the touch for some time after the system has been
powered down. Allow the heat sink and processor to cool before handling them.

sink is necessary to maintain proper thermal conditions.
