How to Enable a TPM Security Chip

By Jedadiah Casey

The Trusted Platform Module (TPM) installed on certain motherboards is an extra chip that is designed to aid in the generation of certain types of cryptographic keys to use in various parts of the computer. For example, Windows 7 can use a TPM to generate private keys for use in its BitLocker technologies. On many computers that have a TPM device installed, it is disabled by default in the BIOS and must be turned on for it to function.

Step 1

Power on the computer.

Step 2

Enter the BIOS by pressing the appropriate hot key. On most computers, the hot key is either "Del" or "F2."

Step 3

Navigate to the appropriate section with the arrow keys. On some motherboards, the TPM is listed under the "Integrated Peripherals." Other motherboards have a separate "Security" section that the TPM device is under.

Step 4

Press the appropriate key to enable the TPM device. This is different for every motherboard. A common key is "Enter" to enable or disable a selected option.

Step 5

Exit the BIOS and save the changes. On many motherboards, this is accomplished with the "F10" key.

Step 6

Boot into the operating system and install the motherboard-provided device driver for the TPM device.

Tips & Warnings

  • If a driver disc was not provided with the motherboard, check the motherboard manufacturer's website.
