Updating or rolling back devices that affect Trusted Platform Module settings
Enabling Trusted Platform Module (TPM) with pre-boot measurement enables the BitLocker protection
on the system. When BitLocker protection is enabled, updating or rolling back the components such as
RAID controller, NIC, and BIOS require that a recovery password is entered or a USB drive that contains a
recovery key is inserted during the next system restart. For information on how to set TPM settings, see
the BIOS User Guide available at dell.com/support/home.
When Lifecycle Controller detects that TPM security is set to On with Pre-boot Measurements, a
message indicates that certain updates require the recovery password or USB drive with the recovery key.
The message also indicates components that affect the BitLocker.
You can choose not to update or roll back those components by navigating to the Select Updates page,
and then clearing the options for the appropriate components.
