Removing the system board

Prerequisites
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.
CAUTION: Do not attempt to remove the TPM plug-in module from the system board. Once 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 re-installed or installed on
another system board.
