Removing the system board

Prerequisites
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.
CAUTION: If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create a
recovery key during program or System Setup. Be sure to create and safely store this recovery key. If you replace this system
board, you must supply the recovery key when you restart your system or program before you can access the encrypted data on
your hard drives.
NOTE: This is a Field Replaceable Unit (FRU). Removal and installation procedures should be performed only by Dell certified
service technicians.
