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.
