System board
A system board (also known as the motherboard) is the main printed circuit board found in systems. The
system board allows communication between many of the crucial electronic components of the system,
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 of sub-systems such as the
processor expansion cards, and other components.
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 are shipped with your product.
1.
Follow the safety guidelines listed in the Safety instructions section.
2.
Keep the #2 Phillips screwdriver ready.
3.
Follow the procedure listed in the Before working inside your system section.
CAUTION: If you are using the 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. Once
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 re-installed or installed on another motherboard.
