Cannot Enable Trusted Platform Module (TPM) as option is greyed out in BIOS? ›

Enabling TPM Functionality

The TPM missing or not showing in BIOS issue can also happen if you haven't updated BIOS firmware for a very long time. In this case, update the BIOS manually.

TPM initialization

If the TPM is a TPM 2.0 and isn't detected by Windows, verify that your computer hardware contains a Unified Extensible Firmware Interface (UEFI) that is Trusted Computing Group-compliant. Also, ensure that in the UEFI settings, the TPM hasn't been disabled or hidden from the operating system.

Here's how to enable and initialize your TPM chip. Power on your system while tapping the F2 key to enter the system BIOS. Expand the 'Security' section then select 'TPM Security'. Check the box to enable TPM Security, then click 'Apply'.

Platform Trust Technology (PTT) is enabled on these systems by default, causing the TPM to be greyed out in the BIOS (Only one of these trust technologies can be enabled at a time). To enable TPM, PTT protection must be removed from the encryption keys.

The "Compatible TPM cannot be found" error typically occurs when your computer's operating system or specific applications require a Trusted Platform Module (TPM) security, but your computer does not have a TPM chip, or the TPM functionality is not enabled in the BIOS/UEFI.

TPM is used to store the keys used to encrypt you fixed drives. If you disable TPM, the bootup sequence (which normally uses the keys stored in TPM to unlock the system drive) won't be able to find the keys.

Press the Windows key + R to open the Run dialog. Type 'tpm. msc' and press Enter. Choose the "Clear TPM" option from the provided menu.

Where is the trusted platform module TPM located? ›

Typically, it's a separate chip on the motherboard though the TPM 2.0 standard allows manufacturers like Intel or AMD to build the TPM capability into their chipsets rather than requiring a separate chip.

The most common cause of TPMS sensor failure is battery exhaustion. TPMS sensors have built-in batteries with a limited lifespan.

you will have to go into the BIOS and check the TPM setting. I had it happen once after some Windows updates were done. This issue happens sometimes which can be fixed through the BIOS settings of your system , just search for how to enable TPM for your motherboard and you'll have this error gone.

Most retail PC motherboards used by people building their own PC, for example, ship with TPM turned off by default even though it is almost always available to be enabled. If you do not see a Security processor section on this screen your PC may have a TPM that is disabled.

Load BIOS Defaults

Sometimes, loading the BIOS defaults can help in re-detecting the TPM: Enter the BIOS setup. Look for an option to load BIOS defaults, which is usually under the "Exit" menu or a specific option like "Load Setup Defaults." Save and exit the BIOS.

Boot computer using F2 into the BIOS setup mode. Locate the “Security” option on the left and expand. Locate the “TPM” option nested under the “Security” setting. To enable the TPM settings you must check the box saying: “TPM Security” to enable the TPM hard drive security encryption.
