Symptom

You may encounter a situation where the Trusted Platform Module (TPM) 2.0 option is missing from the BIOS setup screen, the Security option, or that there is no TPM present when running the Trusted Platform Module Microsoft management console (TPM.msc) in Windows.

This issue may become apparent as the result of a BitLocker recovery message.

NOTE: This only applies to platforms that support or can be switched to TPM 2.0. (Skylake and Newer systems.)

On computers with encrypted hard drives installed, you may also experience a no-boot situation if the TPM option is missing. Check the BIOS settings to ensure that TPM is not missing. Also, follow the steps below to resolve the missing TPM issue if a no-boot occurs on an encrypted hard drive.

Orsak

No cause information.

Upplösning

NOTE: Dell Technologies recommends that the entire installation bases of applicable systems are updated, not just systems that are presenting issues with TPM.

If you are using UEFI boot mode, it is recommended to download and install the latest TPM 2.0 firmware version from the Dell Support Website on your applicable systems. The firmware is located under the Security category in the list of drivers. This new TPM 2.0 firmware should prevent this issue from occurring in the future.

If using Legacy boot mode, download and install the latest TPM 1.2 firmware version from the Dell Drivers & Download website on your applicable systems. The firmware is located under the Security category in the list of drivers.

NOTE: Please see our article on: How to Successfully Update the TPM Firmware on your Dell Computer
NOTE: Search for drivers on the Dell Support Website by system model, not the service tag, as depending on the service tag entitlement, the TPM firmware files may not be displayed.

If TPM is not present, try the following troubleshooting steps:

  1. Update the system BIOS to the latest version available on the Dell Drivers & Downloads website.
  2. Power off the computer, then disconnect the AC power cable and leave the computer unplugged for about 30 seconds.
  3. Reconnect AC power to the computer and boot to the BIOS setup using the F12 one-time boot menu.
    NOTE: To ensure TPM is turned on, you must press F2 to enter System Setup. Then go to the Security section and check that TPM is set to On under the TPM security settings.
  4. If TPM is restored, continue with normal system operation.
  5. If TPM is still missing from the BIOS setup, contact Dell Technical Support for further assistance.
