TPM or Trusted Platform Module is a security chip on the motherboard which stores all passwords and security-related data. It offers hardware-based, security-related functions if you are receiving an error message Alert! TPM Device Is Not Detected, then this post will help you resolve the problem.
Before we go ahead, you need to make sure if TPM is available on your PC. Old PCs may not have the module. The right way to check is to look into UEFI/BIOS Security settings.
Alert! TPM device is not detected
These suggestions involve updating BIOS and installing drivers. Make sure you know what you are doing or take the help of someone who knows it.
- Enable TPM from BIOS
- Update BIOS
- Reinstall Trusted Platform Module driver
If TPM is missing or not showing in BIOS, follow these suggestions. You will also need an administrator account.
1] Enable TPM from BIOS
If TPM is disabled in the BIOS and Windows or software checks for it, it will throw this error. Enabling BIOS is easy, but it will vary from OEM to OEM. However, it is usually available under the Security section.
2] Update BIOS or UEFI
OEM offers updates to the BIOS/UEFI from time to time, and if the TPM detection has failed all of a sudden, then you need to update it.
Most of the modern PCS now offer software that can update the BIOS without going into the BIOS. If that’s not possible, you will need to check with the Motherboard manual to update it via a USB drive and through the UEFI or BIOS.
It is also recommended to disconnect the power supply or battery and keep it that way. Post 30 seconds, you can reboot, and TPM should work now.

What happens if I enable TPM?
Nothing will happen even if you Enable the TPM. It’s a platform that others can use. So if you are using Bitlocker, the software can choose to save all passwords inside it.
