Enables or disables the Lid Switch.
By default, the Enable Lid Switch option is enabled.
When enabled, it allows the computer to turn on from the off state whenever the
lid is opened.
By default, the Power On Lid Open option is enabled.

The Trusted Platform Module (TPM) provides various cryptographic services
which serve as the cornerstone for many platform security technologies. Trusted
Platform Module (TPM) is a security device that stores computer-generated
keys for encryption and features such as BitLocker, Virtual Secure Mode, remote
Attestation.
By default, the Trusted Platform Module (TPM) option is enabled.
For additional security, Dell Technologies recommends keeping Trusted
Platform Module (TPM) enabled to allow these security technologies to fully
function.
NOTE:
The options that are listed apply to computers with a discrete
Trusted Platform Module (TPM) chip.
Allows you to enable or disable TPM.
By default, the TPM On option is enabled.
For additional security, Dell Technologies recommends keeping TPM On enabled
to allow these security technologies to fully function.
The Attestation Enable option controls the endorsement hierarchy of TPM.
Disabling the Attestation Enable option prevents TPM from being used to
digitally sign certificates.
By default, the Attestation Enable option is enabled.
For additional security, Dell Technologies recommends keeping the Attestation
Enable option enabled.
NOTE:
When disabled, this feature may cause compatibility issues or loss of
functionality in some operating systems.
The Key Storage Enable option controls the storage hierarchy of TPM, which is
used to store digital keys. Disabling the Key Storage Enable option restricts the
ability of TPM to store owner's data.
By default, the Key Storage Enable option is enabled.
For additional security, Dell Technologies recommends keeping the Key Storage
Enable option enabled.
NOTE:
When disabled, this feature may cause compatibility issues or loss of
functionality in some operating systems.
Allows you to control the hashing algorithm that is used by the TPM. When
enabled, the TPM uses the SHA-256 hashing algorithm. When disabled, the TPM
uses the SHA-1 hash algorithm.
By default, the SHA-256 option is enabled.
