TPM Device Not Detected: Why and 9 Best Fixes

It’s not a good feeling when you get an error on your system. And it’s troublesome when it won’t let you move forward without an immediate fix. Microsoft users complained about one of these errors: TPM device not detected.

If you or someone around you has encountered it, you are going to solve it in minutes. And so we collected the causes and possible solutions to the problem.

What is TPM?

A TPM (Trusted Platform Module) is a module built into your system’s motherboard. Its job is to protect your machine and its hardware with built-in cryptographic keys. This is a rather important chip for performing cryptographic operations on your computer.

But what does it protect your system from?

Well, cryptographic functions and their associated keys are useful for security reasons. They help in storing passwords and encryption settings. Simply put, TPM helps implement security-based configurations more smoothly. One example would be BitLocker.

Hence, the useful TPM chip and security layers provide protection against various threats.

Why is TPM important?

If you are using Windows 10 or earlier, TPM is disabled by default. But you can always turn it on yourself and further secure your device.

A major change has come with Windows 11, where a TPM device is now mandatory. What else? If you are about to upgrade your PC to Windows 11 and you don’t have a working TPM, the upgrade will fail.

If you tried to do this with a non-functioning TPM, you may have seen this error message: “Windows 11 cannot run on this computer.”

But if you’re getting this despite a working TPM, skip to the next section. You should be able to fix the TPM Device Not Detected error.

What causes the “TPM device not found”error?

There can be many reasons why TPM discovery fails. So far, some of them have appeared frequently in most cases.

1. Your computer has an outdated BIOS
2. The TPM chip on your computer is damaged
3. Your device does not have a TPM chip
4. Your computer is having problems with TPM keys

1. Your machine has an outdated BIOS

The BIOS (Basic Input/Output System) is the firmware that plays a critical role in improving the performance of your computer. This is a computer program useful in the process of starting the machine. It is also responsible for the correct loading of the OS.

This software is used by your machine’s microprocessors to restart. Various computer or laptop manufacturers release BIOS updates. And if you don’t apply these updates, your BIOS firmware may be out of date.

2. The TPM chip on your computer is damaged.

Yes, the chip that keeps your car safe can be compromised. You may be trying to make changes to your TPM settings. And at the same time, if you skip even one step, it can damage the TPM chip.

It can also have adverse effects if you try to use another machine to flash your machine’s TPM.

3. Your device does not have a TPM chip

If you are using an older Dell laptop such as the Dell XPS or Precision, the TPM may be configured in the BIOS. Or it may not be present in the Windows system or OS. In such cases, you may encounter the TPM device not found error.

4. Your computer is having problems with TPM keys

Although this is a deep topic, in this case, the problem may be related to the driver. In some cases, the TPM chip uses an OEM driver to support its operations.

While this is acceptable on the hardware level, you run into problems with the software. Thus, it would be helpful if you switched your TPM to the built-in TPM driver.

9 Ways to Fix TPM Device Error

1. Check TPM on your device
2. Enable TPM in BIOS
3. Disable battery
4. Update TPM drivers
5. Reinstall TPM drivers
6. Update BIOS
7. Reset or Rollback BIOS
