Microsoft also upped the system requirements for running Windows 11. Among all requirements, the requirement for a TPM hardware chip frustrates everyone who wants to try Windows 11. Even when the TPM Hardware chip is available on the motherboard, users get a ‘TPM Device Not Detected’ error.
So, if you want to try Windows 11 but cannot because of this error, continue reading the guide.
What is TPM?
It is important to understand what TPM is and how it works before understanding why the error appears.
TPM, or Trusted Platform Module, is a hardware chipset placed on a PC or laptop motherboard. It’s an international standard for a secure cryptoprocessor.
TPM is all about security. It offers hardware-level protection and encrypts disks using Windows features like Bitlocker, Windows Hello PIN, etc. For proper security, TPM 1.2 or 2.0 is mandatory on Windows 11; without it, you can’t install the operating system.
Now that you know what TPM is, you may want to fix the error to install Windows 11. Here are the best ways to fix the error.
1. Make sure your motherboard has a TPM Chip
Before you attempt to resolve the error, you should check whether your motherboard and CPU have a TPM chipset.
TPM device not detected error message can mean that your motherboard doesn’t have it. If TPM is not available, you can’t do anything.
So, it’s recommended to look up your motherboard & CPU online to see if it has TPM 2.0 listed as an official part of device specifications.
2. Check if TPM is Enabled in BIOS
If TPM is available on your PC but you still get the error, check if it is enabled in the BIOS. If it is not enabled, you can enable it to fix the error message.
Enabling TPM from a BIOS/UEFI isn’t very easy because the BIOS differs depending on the motherboard’s brand and model. Watch some YouTube videos or check the motherboard manual for instructions on how to do this.

3. Update BIOS or UEFI
If the TPM is already enabled on the BIOS or UEFI, but you still get the error message, it’s time to update the BIOS or UEFI.
However, updating the BIOS could be difficult, especially if you lack technical knowledge. Incorrect BIOS settings can lead to various problems that cannot be easily fixed.
The safest way to Update your BIOS is to disable the Bitlocker device encryption, visit the OEM website, and download the latest BIOS firmware for your PC. Once downloaded, run the installer file and follow the on-screen instructions.
Another option is to take your PC or laptop to the nearest service center and ask them to update the BIOS. This is the safest way to update the BIOS/UEFI firmware.
4. Reinstall the TPM Driver
If the TPM 2.0 shows up in your Device Manager, you can reinstall the TPM driver. Here’s what you need to do.
1. Click on Windows Search & type Device Manager. Open the Device Manager app from the list.
2. When the Device Manager opens, expand the Security Devices.
3. Right click on the Trusted Platform Module and select Uninstall Device.
4. On the confirmation prompt, click on the Uninstall again.
5. Once the TPM driver is uninstalled, restart your computer.
5. Unplug the Battery/CMOS
This is a very common solution for resetting the PC BIOS. If you have a laptop, you can power down the device and remove the battery.
If you have a desktop computer, you need to open the CPU cabinet and remove the CMOS. For those unaware, CMOS is the term for the memory on a computer motherboard that stores the BIOS settings.
Removing the CMOS battery removes all BIOS settings. So, you can try removing the CMOS battery (only if you have technical knowledge) to reset the BIOS settings to default.
6. Bypass the Windows 11 TPM Requirements
Those who want to enable TPM for Windows 11 installation can rely on this method. There’s a way to bypass Windows 11’s TPM Requirement; you must use several third-party apps.
You must check out our guide – How to Bypass Windows 11 TPM Requirement, to explore all available options. Another easier method is to create a Bootable USB drive with the Rufus utility.
Rufus provides an option to remove the Secure Boot and TPM 2.0 requirements. To bypass the Windows 11 requirements using Rufus, check out this guide – How to Create a Bootable USB to Bypass Windows 11 Restrictions.
7. Contact Technical Support
If your motherboard has a TPM chip and the BIOS settings are correct, you should seek technical help.
You can contact a nearby technician to have them fix the issue, or you can contact your PC or laptop manufacturer for help.
This guide is about fixing the ‘TPM Device Not Detected’ error. If your PC has a TPM chip and you’ve followed all methods, the issue was likely already fixed. Please let us know which method worked for you to fix the Windows 11 TPM error.
