Windows 11 has been announced, and among Windows 11 requirements is TPM. 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’re going to show you what you can do if the TPM device is not detected on your PC.

What do I do if the TPM device is not detected on my PC?

1. Check if you have a TPM device

  1. Press Windows Key + R shortcut and enter tpm.msc. Press Enter.
  2. A new window will appear and you’ll see the status of your TPM device.

If you get a message saying that TPM cannot be found, you may not have a TPM chip or the TPM might not be enabled.

2. Enable TPM in BIOS

  1. Access BIOS.
  2. Go to the Advanced or Security section.
  3. Look for the TPM feature end enable it.

Keep in mind that each version of BIOS is different and there’s no single and universal way to enable TPM. For detailed instructions, we advise you to check your motherboard manual.

For detailed instructions, we highly recommend that you check your motherboard manual and see how to properly upgrade TPM and BIOS firmware.

4. Disconnect your PC from the power outlet

This is a pretty simple workaround, and if the TPM device is not detected, just disconnect your PC from the power outlet.

Leave the PC disconnected for a minute or two and then connect it to the power outlet and start it again.
