System board
A system board (also known as the motherboard) is the main printed circuit board found in computers. The system board allows
communication between many of the crucial electronic components of the computer, such as the central processing unit (CPU)
and memory, and also provides connectors for other peripherals. Unlike a backplane, a system board contains significant number
subsystems such as the processor expansion cards, and other components.
Removing the system board
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 Trusted Program 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.
CAUTION: Do not attempt to remove the TPM plug-in module from the motherboard. After the TPM plug-in
module is installed, it is cryptographically bound to that specific motherboard. Any attempt to remove an
installed TPM plug-in module breaks the cryptographic binding, and it cannot be reinstalled or installed on
another motherboard.
