TPM Device Not Detected? Here’s How To Fix It – 2024

TPM Device Not Detected?

TPM Device Not Detected: The TPM (Trusted Platform Module) is a device connected or soldered to the motherboard that stores personal information.

Therefore, when we encounter an error message ” TPM device not detected”, The system cannot detect this chip when it boots.

We can choose to either click Continue, enter BIOS setup or Diagnostic. However, if we click Continue and start the system, as usual, we can’t disable Bitlocker any longer.

Because all Bitlocker’s passwords and encryption are stored in the chip TPM, we cannot access them if the system does not recognize the chip.

In this post, we have provided a list of causes and remedies to repair the system if it can not recognize this Trusted Platform module chip.

What Is TPM?

TPM stands for Trusted Platform Module. It is an embedded chip inside your laptop’s motherboard, which can perform cryptographic functions in your Dell laptop’s system.

It helps secure the laptop’s hardware by integrating cryptographic keys. That is, it works to safeguard your computer from security concerns and malware.

Different computers use it to authenticate and authorize the data and files. This error message is displayed when the TPM processes on your laptop; therefore, a part of your laptop’s security has been affected.

BitLocker features employed by Windows may be behind this. However, BitLocker is also a crucial component as a stand-alone feature and deactivating it could result in other problems for your laptop.

Therefore, although the most straightforward solution could be to disable BitLocker, this isn’t the option.

What Causes TPM Device not Detected Error?

Before we get started with the fix, we need to understand why computers cannot recognize the chip.

Another issue we encounter when the system fails to detect devices with TPM is that users cannot upgrade their system in Windows 11. So, this issue needs to be solved to move to Windows 11.

Here are some suggestions to try if the system cannot detect the Trusted Platform Module.

Remove the Power Supply

There may be a problem with the power supply that causes the Trusted Platform Module (TPM) to malfunction because of unknown causes.

A simple restart could fix the issue. However, a remaining charge inside the motherboard’s capacitor can cause the same problem even after restarting.

Therefore, it is recommended to disconnect all power sources entirely and eliminate all capacitors. After removing the power source from the wall socket, hit the power button five to six times to drain the capacitors.

If you’re on laptops, we recommend taking the battery off while pressing the power button several times to drain the capacitors.

After you have completed the process after which you have completed the process, plug your computer back in and switch it on. The system should be able to recognize the TPM chip. TPM chip. If not, the solutions listed below might work for you.

After your firmware has been updated, the only thing you need be doing is to restart the Dell laptop, and hopefully, the issue will be resolved.

Enable TPM

If your computer cannot recognize its Trusted Platform Module (TPM), it is likely, that the settings for TPM on the computer are not working.

If this is the case, we have to enable the TPM settings. Two versions exist of TPM, TPM 1.2 and TPM 2.0. It is possible to follow the same process to allow each version of TPM.

Follow the steps below to Enable TPM.

  1. Input your motherboard’s BIOS using the keys DeltF2 or F9 during boot-up, depending on the manufacturer.
  2. Search for the option called Security.
  3. Then, search for Then, locate Intel Platform Trust Technology (IPTT) or AMD CPU FTPMAllow The TPM utility’s transparency. This process could be different because there could be a checkbox or toggle bar to turn on or deactivate the TPM utility.
  4. Then, choose Save and go to the exit.

NOTE: This solution may not work on your system since the manufacturer uses various names for every setting. So, we must look for locations that correspond to the above search terms.

After the computer has started, the system will be able to recognize the TPM chip. Consider other solutions as described below if the BIOS doesn’t detect the TPM setting.

Udpate/Rollback BIOS

Because the BIOS(Basic Input/Output System) manages all the computer’s hardware components, both external and internal, this component can begin to fail when we fail to conduct a BIOS updating every once in a while.

The same situation applies when it comes to TPM chips. TPM component, i.e., there might be an issue diagnosing this component if we don’t change the BIOS.

When performing the BIOS update, it is essential not to interfere because the loss of power during the BIOS update can lead to an unsound motherboard.

Most of the time, upgrading the BIOS can effectively fix this problem. However, if you experience this issue following an update to the BIOS, we may need to change your motherboard’s BIOS.

To reverse the BIOS update, first, you must download the version we want to use for the motherboard BIOS from the manufacturer’s official website.

NOTE: When upgrading the BIOS version from 1.15 to 1.16 on the Dell laptop, we encounter problems with the system device not being able to detect the chip. Therefore, downgrading the BIOS might be the best solution for you.

Reset BIOS Defaults

Reset BIOS Defaults

If the firmware on your laptop is fully updated, but you’re experiencing similar error messages, then you’ll need to be able to change the BIOS defaults.

This could be because you did not update the firmware correctly, and you need to restore it to its default state, or this procedure could function on its own and aid your laptop in recognizing the chip in your TPM.

Start by shutting off your laptop and ensuring it’s not connected to any power source. Press both the ESC or CTRL buttons on your keyboard, click the power cable, and then press the power button. When your laptop has started, you can let go of ESC and CTRL keys.
