Dell Latitude E6520 (Early 2011) - Manual (Page 2)

You will see the configuration-mode label like one below. Numbers or options
will vary depending your selection when you purchased the computer.
NOTE: If the original configuration-mode label is damaged, or otherwise illegible,
contact Dell to obtain your configuration-mode number (see your computer
documentation for contact information).
3 Replace the bottom access panel.
NOTE: For information on replacing the system board, see "Replacing the System
Board" in your Service Manual.
4 Disconnect the network cable, if applicable, and the mass storage devices like
hard drives or USB flash keys.
5 Connect the AC adapter and turn on the computer.
An initialization screen is displayed. The green text on the initialization screen
prompts you to select the appropriate configuration for your computer.
CAUTION: Ensure that you use the correct configuration-mode number. Once you
have selected a configuration, you cannot change the management mode as this
process is not reversible. If you make the wrong selection, your computer may not
operate as it should.
6 Enter the configuration-mode number that you obtained from the label inside
the bottom access panel.
7 If this is the correct configuration-mode number, select Y at the prompt.
Once the initialization is complete, the computer shuts down.
8 Reconnect the network cable and the mass storage devices like hard drives or
USB flash keys.
9 Restart the computer.
