System board 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 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. 1. Follow the safety guidelines listed in Safety instructions. 2. Power off the system and all attached peripherals. 3. Disconnect the system from the electrical outlet, and disconnect the peripherals. 4. Open the drive bays, remove all drives, and then close the drive bays. 5.
