TPM Device not Detected: 3 Simple Methods to Activate it

Windows 11 has been announced, and among the Windows 11 requirements, there is also a requirement for TPM. However, many users reported that the TPM device is not detected on their PC, and they won’t be able to upgrade to Windows 11 due to this issue.

Speaking of TPM, many users reported TMP 2.0 errors while trying to install Windows 11, so it’s safe to say that this is a widespread issue at the moment.

However, there’s a way to fix this problem, and in this guide, we will show you what you can do if the TPM device is not detected on your PC.

Why is my TPM not detected?

There are several reasons why your TPM (Trusted Platform Module) might not be detected. Here are some possible explanations:

• Disabled TPM – The TPM may have been disabled in the BIOS settings. 
• Outdated BIOS – An outdated BIOS can sometimes cause issues with TPM detection. 
• TPM firmware issues – If the TPM firmware is corrupted or outdated, it can cause detection issues. 
• Hardware issues – A faulty or damaged TPM module can cause detection issues. If you suspect this is the case, contact your device manufacturer or a qualified technician for assistance.
• Security software – Some security software can interfere with TPM detection. 
• Motherboard issues – In some cases, there may be issues with the motherboard that prevent the TPM from being detected. This can be difficult to diagnose and may require professional assistance.

Depending on the cause of the problem, you may try any of the solutions we recommend below.
