What is TPM state in BIOS? Answered September 24, 2019. TPM state tracks whether the Trusted Platform Module has been initialized and owned - associated with a single user- the operating system. It prevents TPM reset and initialize commands from executing unless the state is set appropriately in the system's firmware.

There is a BIOS option to enable or disable the device , like you would with any other integrated peripheral, such as network card or serial port. The TPM enables SecureBoot and disk encryption key storage for the operating system.
What is TPM state?
Once enabled, the TPM state will be the current state of the installed TPM, as configured previous by any operating system. The states should be named similar to ‘active’, ‘not owned’, ‘initialized’, ‘owned’, ’cleared’. You can disable the TPM, it will remain owned and secrets will be kept stored. The device will not be detected or usable or reset.
What happens if an operating system doesn't protect TPM?
If for instance an operating system doesn’t protect TPM administration by privilege restrictions, a user could ask the TPM to re-initialize, losing the operating system’s ownership (only user with master key to secret storage).
What is a TPM?
TPM is a chip that encrypts your drive. If CMOS (bios) settings change, you'll be locked out of your machine without a code. This is good if you don't want anyone getting sensitive information. Bad if your drive fails and you have no backups — the chances of recovering the data are basically non existent.
How to make TPM available?
Step 1: First, Restart the system and go to the 'Startup Menu' through F1, F2, F10, F11, DEL or another required key. Step 2: After pressing the desired key, you need to click on the 'Security Tab' and go to 'TPM device.' . Step 3: Now, select 'Available' on the list and save it. Restart your PC to enable the TPM.

For instance if you want to boot another operating system temporarily without it being able to alter or own the TPM. Version 2.0 of TPM may be different versus my experience with 1.2.
When should I update my BIOS?
If you don’t have a custom PC , then you probably shouldn’t update the BIOS unless you’ve encountered an issue where it is necessary to do so. If you have a Custom PC, I recommend updating the BIOS when you first build your PC, and, assuming that the motherboard is fairly new, after 8–12 months (optionally).
What is TPM in computer?
With a TPM, private portions of key pairs are kept separate from the memory that is controlled by the operating system. Keys can be sealed to the TPM, and certain assurances about the state of a system (assurances that define the trustworthiness of a system) can be made before the keys are unsealed and released for use.
Where is the TPM installed?
The TPM is usually installed on the motherboard of a computer, and it communicates with the remainder of the system by using a hardware bus. Computers that incorporate a TPM can create cryptographic keys and encrypt them so that they can only be decrypted by the TPM.
