Removing the system board
Prerequisites
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 system board. After the TPM plug-in module is
installed, it is cryptographically bound to that specific system board. Any attempt to remove an installed TPM plug-in
module breaks the cryptographic binding, and it cannot be reinstalled or installed on another system board.
