When encountering a "TPM device not detected" issue on a Dell Vostro 5568, there are several steps you can take to troubleshoot and potentially resolve the problem.

• Run Dell’s built-in diagnostics (press F12 at boot → Diagnostics) and check TPM-related tests if available.

3. Ensure the Startup type is set to Automatic.
