Troubleshooting

For troubleshooting information, see Troubleshooting System Fundamentals Testing.

If this test fails, review the test log from Windows Hardware Certification Kit (Windows HCK) Studio.

  1. Check test output directly from command prompt when the test runs or open te.wtl in the HCK Manager.

  2. If a test script fails, check the BitLocker status:

    • Manage-bde –status [volume]

  3. Collect BitLocker event logs from event viewer at two locations:

    • Filter \Windows logs\System logs by event sources started with BitLocker

    • Applications and Services Logs\Microsoft\Windows\BitLocker-API\Management

  4. Check TCG logs

    • Collect TCG log (*.txt).

    • Compare multiple copies of the TCG log and see whether PCR [7, 11] are consistent across reboot and hibernate.

    • Make sure WHCK tests with TPM in the name pass.
