The “TPM Not Detected” Error: Fixed
FAQ

It’s easy to find yourself in a fit of confusion when you see the TPM error since the device is now becoming more integral to security features. Apart from being unable to run Windows 11, systems that magically stop detecting their TPMs may also lose access to important encryption keys , saved passwords, and other security information. Thankfully, there are different ways to resolve the error on laptops and desktops and Windows 11 and 10. I’ll outline these methods and explain why the error occurs.

What Is a Trusted Platform Module (TPM)?

A Trusted Platform Module is a dedicated security chip embedded in a motherboard, available as a separate hardware module, or integrated into a CPU. A TPM can also be provided as separate firmware installed in a computer’s chipset. It provides hardware-based security functions, which means it generates and store cryptographic keys, saves passwords and digital certificates, and verify boot integrity to protect against sophisticated attacks. So, see it as a safe that holds the keys necessary to open your computer and unlock other functions and components.

Note

For example, whenever you turn on your TPM-enabled computer, the chip checks your computer status using various indicators. If everything is normal it will provide the encryption keys required to unlock your hard drive and boot your system. That way, your computer won’t boot if hackers attempt to change the startup process.

Microsoft now integrates TPM with various Windows encryption and sign-in processes, such as BitLocker and Windows Hello. However, it is more integral to Windows 11 and is used for boot verification.

Windows now loads encryption keys onto the chip instead of using the system memory. This method ensures that only the chip can provide encryption keys for features like BitLocker whenever you want to decrypt your hard drive.

How to Check if the TPM Is Working

The first step in troubleshooting the issue is confirming whether Windows is correctly reporting that you do not have a TPM. To do that, you must verify that your computer has a Trusted Platform Module and that it is working. There are different ways to confirm.

Let’s show you how.

Method 1: Using the Command Prompt

Follow the steps below:

Open the Start menu and type CMD.
Click Run as administrator under Command Prompt on the results page.
Once the Command Prompt opens, type tpm.msc and press Enter .

Once the Command Prompt opens, type tpm.msc and press Enter

The Trusted Platform Module (TPM) Management on Local Computer window will now show up with a message indicating whether your computer has a working TPM chip.

The Trusted Platform Module (TPM) Management on Local Computer window will now show up with a message indicating whether your computer has a working TPM chip

If your computer has a TPM, the window will show a small description under the Overview section. It’ll tell you whether the module is ready to use under Status and indicate the TPM’s manufacturer under TPM Manufacturer Information .

If your computer does not have a TPM chip, you should see a message that reads:

“Compatible TPM cannot be found.”

However, another detailed message offers the following advice:

“Verify that this computer has a 1.2 TPM or later and it is turned on in the BIOS.”

If your computer does not have a TPM chip, you should see the message Compatible TPM cannot be found.Verify that this computer has a 1.2 TPM or later and it is turned on in the BIOS.

We’ll cover that later. Now, let’s continue with other methods for checking your TPM status.

You should see the Reset button in the bottom corner (left or right) of your screen. In some cases, the key guides will be displayed at the top of the BIOS interface.

After resetting your BIOS, go to the Advanced or Security tab to check that your TPM is turned on. That is because some manufacturers turn the module off by default.

Fix 9: Change your TPM version

Older systems generally run TPM 1.2 out of the box, but manufacturers usually provide utilities that allow users to upgrade.

Microsoft and other software developers favor TPM 2.0 because it has more advanced hardware-based security features. As such, applications and certain system processes may trigger errors when dealing with version 1.2.

For instance, people who can’t install Windows 11 also see an error that reads, “ This PC must support TPM 2.0 .”

In most cases, Microsoft and your OEM will automatically upgrade your module, especially if you move to Windows 11. My TPM version was 1.2 the first time I installed Windows 11, but it has since changed to 2.0, and I never had to upgrade manually.

Installing the latest version of Windows through the Windows Update utility may be all you need to upgrade your TPM version. Sometimes, there are backlogs of Windows Update that do not install until you open the client and initiate the process.

That said, you can follow your computer manufacturer’s instructions on how to upgrade the security module on your system. You may be prompted to install a dedicated TPM upgrade utility. Ensure you follow instructions carefully and correctly.

The TPM (Trusted Platform Module) is a chip that is soldered or attached to the motherboard which stores personal data. So, when we get the error message “TPM device not detected“, the system cannot detect this chip during boot.

What Causes TPM Device not Detected Error?

Before we start with the fixes, let us see why a computer cannot detect the TPM chip.

Outdated BIOS
TPM chip damaged
Network connection issues
Problem with TPM keys

How to Fix TPM Device not Detected Error?

Here are some solutions you can try if the system cannot detect Trusted Platform Module.

Remove the Power Supply

Sometimes, there may be a power usage issue that can cause the Trusted Platform Module to malfunction due to unknown reasons. A simple restart may solve this issue, but there is always some charge left in the motherboard capacitor, resulting in the same problem even after a restart.

So, it is ideal to remove the power source completely and discharge all the capacitors. Once you remove the power supply from the wall outlet, press the Power button five to six times to discharge the capacitors.

If you are on a laptop, we recommend removing the battery and pressing the power button multiple times to discharge its capacitors.

Once you complete the process, plug the computer back in and turn it on. The system should detect the TPM chip. If not, our solutions mentioned below may work for you.

Enable TPM

If the computer does not detect the Trusted Platform Module, it is most probable that the TPM settings in the computer are disabled. If so, we need to enable it. There are two versions of TPM, TPM 1.2 and TPM 2.0. We can follow the same process to enable both versions of TPM.

You can follow these steps to Enable TPM.

Enter your motherboard’s BIOS by pressing Delt, F2, or F9 during startup, depending on the manufacturer.
Look for the option named Security.
Then, locate TPM, Intel Platform Trust Technology (IPTT), or AMD CPU fTPM. Enable TPM visibility. This step may be different as there may be a checkbox or a toggle bar to enable or disable the TPM utility,
Now, select Save and exit.

Note: This solution may not apply to your computer, as the manufacturer has different names for each setting. Therefore, we need to search for settings that best match the above keywords

Once the computer starts, the system should detect the TPM chip. Try other solutions mentioned below if the TPM setting is not seen in the BIOS.

Udpate/Rollback BIOS

As the BIOS(Basic Input/Output System) controls all computer’s internal and external hardware components, this component may start to malfunction if we do not perform a BIOS update every now and then. It is the same case for the TPM chip, i.e., there may be an error while detecting this component if we do not update the BIOS.

When performing a BIOS update, we should not interfere as power loss during a BIOS update may result in a corrupted motherboard.

Mostly, updating the BIOS will work perfectly on solving this issue. However, if you notice this error after a BIOS update, we may have to downgrade the motherboard BIOS.

To roll back a BIOS update, first, we need to download the desired version of motherboard BIOS from the official manufacturer’s website.

Note: When upgrading the BIOS version from 1.15 to 1.16 in the Dell laptop, we face issues with the system device not detecting the TPM chip. So, downgrading the BIOS may be the solution for you.

Reset BIOS

In the above solution, Enable TPM, if the BIOS does not include the option to enable the TPM settings, we need to perform a BIOS reset. Doing so will revert all its settings to default which will make the system detect all hardware along with their configurations.

Here are a few ways you can reset BIOS.

Reset option in BIOS itself.
Remove the CMOS
Reset using a jumper

Note: Resetting the BIOS will not reset the OS.

Update TPM Driver

Another reason the system is not detecting the Trusted Platform Module device is an outdated TPM driver. As the TPM chip is a physical chip, it does require a driver for the OS to communicate with it.

To update the TPM driver, open the Device Manager by pressing the Windows key and X simultaneously. Now, expand Security Devices and right-click on Trusted Platform Module 2.0 (or Trusted Platform Module 1.2, depending on the computer’s TPM version). Click on Update driver. Then, click on Search automatically for drivers.

Once the update is complete, restart your computer to check if the issue still persists.

Troubleshoot Network Connection

According to official Microsoft documentation, if the system uses Windows 10, version 1507 or 1511, or Windows 11, the computer will have a hard time detecting and initializing TPM if there is a network connection issue.

Along with this, if the system admin has configured the computer to require the TPM recovery information to be saved in ADDS (Active Directory Domain Services) and if the computer cannot reach its domain controller, it cannot initialize the TPM.

To solve this issue, we can run the network connection troubleshooter to check for any problems regarding the internet connection. Also, if the system administrator has configured the TPM information to be saved in ADDS, we need to disable this feature. You can follow these steps to disable TPM recovery in ADDS.

Note: Settings mentioned in the two processes explained below may or may not be available on your computer.

Warning: Wrong registry changes can have a negative impact on your operating system and even cause it to malfunction.

Press the Windows Key and R simultaneously.
Type “Regedit” without the quotation mark and press Enter.
Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\TPM.
Now, on the right panel, double-click on ActiveDirectoryBackup and set the Value data as 0 to disable the policy. Repeat the similar process for RequireActiveDirectoryBackup.

If the Registry does not have these values, we can use the Group Policy Editor to turn off TPM backup to ADDS.

Press the Windows Key and R simultaneously.
Type “gpedit.msc” and press Enter.
Navigate to Administrative Templates > System > Trusted Platform Module Services.
On the right panel, double click on Turn on TPM backup to Activate Directory Domain Services.
Check Not configured or Disabled.
Click Apply, then OK.

The Group Policy Editor utility is only available on Windows Professional and Enterprise edition. Windows Home edition users need to enable the Local Group Policy Editor feature using a third-party tool.

Clear all keys from TPM

We can use the Windows Defender Security Center utility to clear the TPM values as a final solution before replacing the TPM chip itself. Clearing the TPM values will erase all information inside the TPM chip, reset it to the default state, and delete data protected by those keys.

Warning: Back up all your data before performing this step as you may lose files and folders, including access to encrypted data.

You can follow these steps to clear the TPM.

Press the Windows key + I.
Go to Privacy & security > Windows security > Open Windows Security.

The Trusted Platform Module (TPM) is a piece of physical security hardware embedded in your motherboard. The TPM module stores encrypted keys inside the hardware chip. It is a minimum requirement to install Windows 11.

Often, the TPM module can go haywire and throw an error. For example, you may come across one of the following black screens/error messages:

Alert! “TPM device not detected”
Device health attestation isn’t supported on this device. Clearing your TPM might help enable it.

If you are experiencing an issue with your TPM while sure that it is present in your hardware, there are a few things you can do to fix it, including resetting and clearing the TPM.

Causes of TPM Device Not Detected

Even a perfectly-working TPM device can act up and suddenly disappear from your computer. But rest assured, it is still there. There can be several reasons why a TPM device is not detected error message:

TPM is disabled.
TPM chip is damaged.
An issue with the TPM keys.
Your BIOS/UEFI is outdated.
The TPM driver is outdated or corrupted.

Below you’ll find a solution for either of these causes and get your TPM up and running again.

Troubleshooting TPM Device is Not Detected Error

Perform the following solutions chronologically to rule out all possible causes for the system not detecting the TPM.

Enable the TPM Module from Firmware Settings

It may be possible that the TPM has been disabled from your BIOS/UEFI settings. Make sure it is enabled or enabled using these steps:

Enter your system firmware settings.
Open the TPM Security settings.

You can find the TPM security settings under the Security section.
Enable TPM.

Enable TPM from firmware
Check the box next to “TPM on” and enable it.
Exit BIOS/UEFI settings.

Now check to see if the issue has been resolved. If it hasn’t, or TPM was already enabled, then you can go about it another way.

Update TPM Driver

An outdated TPM driver can also cause it to not be detectable. If you have setup BitLocker with TPM in your system, the TPM drivers must be the ones provided by Microsoft. If you have installed a non-Microsoft driver, Bitlocker will not detect the TPM modules on your computer.

Update your TPM driver to the latest version using these steps:

Open Device Manager.

Type in devmgmt.msc in the Run Command box.
Expand Security Devices.

Expand Security devices
Update the Trusted Platform Module driver.

Картинка с сайта: www.itechtics.com

Update TPM driver
Right-click on TPM and then click Update driver from the context menu.
Search for drivers.

Картинка с сайта: www.itechtics.com

Search automatically for newer drivers
Click Search automatically for drivers, and the wizard will then begin searching the web for newer available drivers and install them.
Close the driver update wizard.

If the latest driver is already installed, you can reinstall it or try to manually update the driver.

Then check to see if the issue has been resolved and if TPM is being detected again.

Editor’s note: On my old Dell laptop with Windows 7 operating system, Bitlocker entered recovery mode once I reinstalled the driver. After manually entering the password, the system booted up normally.

You don’t need to worry about this if you are using Windows 11 or Windows 10, that use UEFI mode with TPM 2.0. These modern OS will automatically initialize the TPM module for you.

Update Firmware

It is possible that an outdated or corrupted system BIOS/UEFI can cause the TPM to become undetectable. However, updating the firmware can be fatal for your computer if done incorrectly. Therefore, we suggest that you be very cautious during the process and create a system restore point just in case.

Start by checking your system’s BIOS version, and then cross-reference it online to confirm whether there is an update available.

To check your system’s BIOS version, type in msinfo32 in Run and then check the version in front of BIOS Version/Date.

Check BIOS version

Now go to the manufacturer’s website, put in your system’s details, and check if a new version is available. If there is, we suggest that you install it on your device.

Once the firmware is updated, check if your TPM is now detected and the issue is resolved.

Reset TPM

Issues within the TPM keys can cause it to malfunction, and thus Windows or firmware cannot detect it. In this case, you can try resetting the TPM.

Resetting the TPM will not result in any data being lost.

Note: Resetting the TPM is not the same as clearing it.

Follow these steps to reset the TPM in a few easy steps:

Shut down the computer.
Remove the AC power.
Remove the battery (in the case of a laptop).
Press and hold the power button for at least 60 seconds.

This will discharge any static power in the motherboard capacitors and other components.
Reconnect the battery and AC power.
Turn on the computer.

As soon as the computer turned on, the TPM would have lost all power and reset itself. Check to see if this resolved the issue for you.

If this doesn’t, then the only thing left to do is clear the TPM.

Clear TPM

Clearing the TPM means clearing out all keys and other data on it. This means all keys will be lost. There are different ways to clear the TPM. But before we do, you must consider that all keys associated with the TPM will be lost, as well as the data protected by those keys.

Hence, take a backup of all critical data before proceeding.

Once you are sure that all data is backed-up and you are ready to clear the TPM, follow any one of these methods.

Note that you can only clear the TPM when it is detected. Hence, this solution can only be used if you are not encountering a “TPM device not detected” error, but some other problem with the module.

Closing Thoughts

Regardless if your device has TPM 1.2 or TPM 2.0, the solutions provided in this post will work for both.

Before Windows 11, TPM was an added security layer to protect your devices from unauthorized physical access. However, Windows 11 has made it compulsory to have TPM 2.0 installed on your system.

That said, if TPM cannot be detected by your computer, your Windows 11 system will still work. However, certain functions like Windows Hello sign-in options won’t work, and many other apps will not be able to authenticate since the keys stored inside the TPM won’t be found.

To ensure maximum security, you must get the TPM detected and functioning again.
