Enabling the Processor Serial Number

The Intel® Pentium® microprocessor includes a processor serial number feature designed to provide additional user security and manageability benefits. By default, this feature is disabled on Dell computers to protect your privacy. However, it can be enabled through the Processor Serial Number option in the system setup program.

NOTICE: Do not change this setting by any means other than the system setup program. Otherwise, your computer may become unusable.

1.Enter the system setup program.

2.When the Main screen appears, press the down-arrow key to highlight the Processor Serial Number option, and then press <Enter>.

3.Select Enabled from the menu, and then press <Enter>.

4.Use the right-arrow key to highlight Exit, and then press <Enter>.

5.When prompted to confirm the changes you made, press <Enter>.

6.The computer restarts with the processor serial number feature enabled.

HINT: The processor serial number feature remains enabled until you disable it in the system setup program.

To disable the processor serial number feature, repeat steps 1 through 5, selecting Disabled in step 3.
