How to test TPM chip to see if it's faulty RRS feed

  • Question

  • Is there a way from within Windows to test the TPM chip on the computer to see if it's ok, or if it's failing or unreliable?

  • Hi RJO22.

    I'm not aware of any kind of user-sided test you could execute to check the status of the TPM chip: the simplest thing you could do is opening the tpm.msc snap-in of the Microsoft Management Console ad check the status of the chip itself. The "Security" section of the Windows Defender Security Center also provides you with some information and troubleshooting for the TPC chip.
    A more comprehensive set of test could be executed by using the Windows Hardware Lab Kit and they're described at https://docs.microsoft.com/en-us/windows-hardware/test/hlk/testref/device-trustedplatformmodule-tests.

    Bye.

  • Thanks, i'm more looking to confirm if the chip is potentially bad, as tpm.msc keeps going from seeing it to not seeing it.

    I came across that same link, but i'm not quite sure how to use HLK, or issue that test once i have it installed.

    You can refer to the "Troubleshoot the TPM" document or execute the Get-Tpm PowerShell cmdlet, which returns information about the Trusted Platform Module (TPM) on the current computer.
    You could execute the below commands from an administrative command prompt

    • wmic /namespace:\\root\cimv2\security\microsofttpm path win32_tpm get IsEnabled_InitialValue to check whether the TPM is enabled
    • wmic /namespace:\\root\cimv2\security\microsofttpm path win32_tpm get IsActivated_InitialValue to check whether the TPM is activated

    Bye.
