7.23 Removing a TPM
● If the private key of the TPM is used to encrypt data, back up the data before
removing the TPM.
If the data is not backed up, the encrypted data cannot be decrypted after the
TPM is replaced.
After the data is backed up, clear the key of the TPM. For details, see "Security"
in the

used. If the removed TPM needs to be reinstalled in the original environment,
you do not need to back up and clear data.

removing the TPM. After replacing the TPM,
congure the related settings on
the BIOS again.
