If you want to know how to Fix ‘TPM Device Not Detected’ issue in Windows 11/10. These days, having a TPM device on your Microsoft Windows computer that is operational is necessary for a variety of functions, and having one is an absolute prerequisite for Windows 11. TPMs are found in virtually all modern computers, but there are occasions when they malfunction.
If you are getting an error message that says your “TPM Device Is Not Detected error,” either when your computer is booting up or while you are using Windows, there are a few potential causes for why this component of your system isn’t functioning correctly. This particular error is almost always associated with Dell Laptops; however, the problem of a missing or malfunctioning TPM is something that can occur with any brand of computer.
What is TPM?
TPM is a chip on the motherboard that keeps your computer safe. Also, it can be built into modern CPUs, but it runs on its own and provides security at the chip level. Using something like Bitlocker Device Encryption is one of the most common ways to see this in action. If it is turned on, the TPM stores the encryption keys so that no one else can get to them. But TPM can be used for more than just this; Windows can use it for many things.
Why is a TPM device important for system security
- It helps show that the computer belongs to you. When you turn on your computer, the TPM makes sure that you are the one logging in. This makes it impossible for someone to pretend to be you and get into your computer.
- It helps keep viruses and attempts to break into your computer at bay. The TPM makes codes that can only be read by your computer. This means that even if a bad guy tries to get into your computer, they won’t be able to because they won’t have the special codes.
- It protects your private information. The TPM is like a safe that keeps important information about you and your computer. It helps make sure that no one else can get to that information without your permission.

- As soon as the driver is gone, restart your computer.
- Now the TPM driver will automatically install, or you can go to the Microsoft website, look for the latest TPM driver download, and install it.
If you see a message that says “Compatible TPM cannot be found,” your PC may have a TPM that is turned off. See How to enable TPM for more information, or check the support information for your PC to find out how to turn on the TPM.
In rare cases, the TPM on your computer may not work because the TPM driver you installed may be broken, missing, or not compatible with BitLocker. In this case, you can fix the problem by putting the driver back on. Note that you need a driver that works with Microsoft for things to work.
Without TPM 2.0, you won’t be able to move from Windows 10 to Windows 11. But if you have TPM 1.2 or higher, you can do a clean install and it won’t make you do that. It’s not recommended, but you can still install it that way. You just can’t be sure that all of the features will work right.
