For moreinformation, see the TPM software documentation and the help files that came with the software.TPM is a hardware-based security feature that can be used to create and manage computer-generated encryption keys. When combined with security software, the TPM enhances existingnetwork and computer security by enabling features such as file protection capabilities andprotected e-mail. The TPM feature is enabled through a system setup option.NOTICE: To secure your TPM data and encryption keys, follow the backup procedures documented inthe Broadcom Secure Foundation Getting Started Guide. In the event of these backups being incomplete,lost, or damaged, Dell will be unable to assist in the recovery of encrypted data.Enabling the TPM Feature1 Enable the TPM software:a Restart the computer and press during the Power On Self Test to enter thesystem setup program.b Select Security→ TPM Security and press .c Under TPM Security, select On.d Press to exit the setup program.e If prompted, click Save/Exit.2 Activate the TPM setup program:a Restart the computer and press during the Power On Self Test to enter thesystem setup program.b Select Security→ TPM Activation and press .c Under TPM Activation, select Activate and press .
