5 Fixes: TPM 2.0 Device Detected but a Connection Cannot be Established on Host

Error: TPM 2.0 device detected but a connection cannot be established on host

Trusted Platform Module (TPM) 2.0 is essential for modern computers, especially when it comes to security features like encryption and secure boot. However, you may encounter the following situations:

• The error message appears when the system starts up.
• Unable to enable BitLocker and other encryption features.
• System update or driver installation failed.

How to resolve TPM 2.0 connection errors

Here are 5 methods to fix the error: TPM 2.0 device detected, but a connection cannot be established.

1. Check and update the TPM driver

Outdated or corrupted TPM drivers can result in TPM 2.0 device detected error. Follow these steps to update them:

1. Open Device Manager (Press Win + X and select Device Manager), and look for the TPM 2.0 device under "Security Devices."

2. Right-click on the Trusted Platform Module 2.0 device and select "Update Driver."

3. If the update is ineffective, try uninstalling and then reinstalling the driver.

2. Check BIOS/UEFI settings

To figure out how to enable the TPM 2.0 module in your system BIOS:

1. Restart the computer and enter the BIOS/UEFI setup interface. Press the designated key (usually F2, F10, or Delete) to enter BIOS/UEFI settings.

2. Look for the “Security” tab or “Advanced” settings.

3. Ensure that TPM (or Intel PTT) is enabled. If not, enable it.

4. Save the settings and exit, then restart the computer.

3. Clear and reinitialize TPM

If the issue persists, performing a TPM reset can resolve some connection problems.

1. Open the TPM management tool (tpm.msc) in the Start menu search box and pressing Enter.

2. Select the "Clear TPM" option in the TPM management console.

3. Follow the on-screen instructions to reset the TPM. After clearing, reinitialize the TPM.

📢Note: Clearing the TPM will remove all keys stored in it.

4. Check for system updates

System integrity issues can interfere with TPM. Use the built-in Windows tools to scan and repair system files:

1. Open the Windows Update settings and check if there are any available system updates.

2. Install all important updates, especially those related to security. For example, outdated firmware can cause incompatibility with TPM 2.0. Ensure that both the TPM firmware and motherboard BIOS are up to date.

5. Check security software

1. Temporarily disable or uninstall security software that may interfere with TPM.

2. Test whether the TPM function has returned to normal。

Understanding more TPM 2.0 errors in Windows

• Error 80090016: TPM Initialization Failed
• Error 0x80280000: TPM Cannot Be Accessed
• TPM 2.0 Compatibility Error in Windows 11

Error 80090016: TPM Initialization Failed This error typically occurs when there is a problem initializing the TPM device. It may result from BIOS misconfigurations, outdated drivers, or issues within the Windows operating system itself. To resolve it, check BIOS settings, update drivers, and run Windows updates.

Error 0x80280000: TPM Cannot Be Accessed This error can occur due to corrupted files, or when the TPM is disabled. Users may also encounter this error if TPM is not recognized by the system. Running system scans (sfc /scannow) and checking BIOS settings can help resolve this error.

TPM 2.0 Compatibility Error in Windows 11: Windows 11 mandates TPM 2.0 for installation, so some users might face compatibility issues with older hardware. In such cases, it’s important to check the version of TPM (it must be 2.0) and whether the motherboard supports this version. If not, you may need to upgrade your hardware.

TPM 2.0, as a hardware-level security module, can effectively protect data, but if it fails, it may result in data being inaccessible or lost. Therefore, regularly backing up data is a necessary measure to ensure data security.

Important: Regularly back up data to prevent data loss due to TPM failure

AOMEI Cyber Backup is a powerful backup and recovery software that supports various backup scenarios, including system backup, disk backup, file backup, and virtual machine backup.

AOMEI Cyber Backup helps you easily protect your valuable data via these features:

• Supporting full system backups and backups of specific files or folders to ensure important data is not lost.
• Creating incremental and differential backups, saving storage space.
• Performing backup and recovery of VMware ESXi and Microsoft Hyper-V virtual machines.
• Providing automated backup strategies to reduce manual operations.
• Quickly executing disaster recovery to reduce business downtime.

How to create a reliable Windows backup using AOMEI Cyber Backup

When a TPM 2.0 device cannot establish a connection, it may result in encrypted data being inaccessible or the system failing to boot. At this point, AOMEI Cyber Backup can play an important role. Next, use AOMEI Cyber Backup to quickly restore the system to its previous state.

1. Launch AOMEI Cyber Backup, schedule "System Backup" to create an image file of your Windows system.

2. Start system restore by clicking on the "Restore" tab at the top of the window.

3. Select the backup image that contains your Windows system.

4. Choose the destination disk where you want to restore your Windows system. Ensure that the destination disk has enough space to accommodate the system image.

5. Click on "Start Restore" to initiate the system restoration process.

Conclusion

Dealing with TPM 2.0 device detection errors can be frustrating, but most of the time, these issues are solvable with a little bit of troubleshooting. By following the steps outlined in this guide—checking BIOS settings, updating drivers, verifying system integrity, and keeping firmware up to date—you can resolve most common TPM 2.0 connection issues. Preventive measures like enabling Secure Boot, using BitLocker encryption, and backing up TPM keys can also reduce future problems.
