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.
How to Fix TPM Device not Detected Error?
Here are some solutions you may 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.
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 may follow these steps to Enable TPM.
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.
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 notperform a BIOS updateevery 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.
