@Jesse L (retired)​ I’m very disappointed with my Dell computer. It developed a problem after an update, which was not my fault. The warranty ran out seven months ago, but I expected a more durable device for the price I paid. I have used laptops from other brands and never had such a bad experience. I already had to replace the battery eight months ago because it drained too fast. Now Iam facing problem with my computer's TPM Module, might be a problem with the motherboard. Is this the kind of service I get for choosing Dell?

If your Dell laptop is showing an error that the TPM (Trusted Platform Module) device is not detected, it could indicate a few potential issues. The TPM is a security component that provides hardware-based security features. Here are some steps you can take to troubleshoot and address the issue:

1. Check BIOS/UEFI Settings:

   • Restart your laptop and enter the BIOS/UEFI settings by pressing the appropriate key during boot (usually F2, F12, Delete, or Esc).
   • Look for TPM-related settings in the BIOS/UEFI. Make sure TPM is enabled and configured correctly.
   • Some laptops might have options to enable or disable the TPM. Ensure it's enabled if available.

2. Enable TPM in Windows:

   • If the TPM is detected in BIOS/UEFI but not in Windows, it might be disabled in the Windows settings.
   • Press Win + R, type "tpm.msc" and press Enter to open the TPM Management Console.
   • If prompted, restart your computer to initialize the TPM.

3. Update BIOS/UEFI and Drivers:

   • Check the Dell support website for BIOS/UEFI updates and driver updates related to the TPM.
   • Outdated firmware or drivers might cause compatibility issues with the TPM.

4. Physical Inspection:

   • If you're comfortable, you can open the laptop and ensure that the TPM module is properly connected to the motherboard.
   • Be cautious and consult your laptop's manual or Dell's support resources for guidance on safely accessing internal components.

5. Clear TPM: (Note: This might require expert assistance or advanced knowledge.)

   • In some cases, the TPM might be stuck in a bad state. Clearing the TPM and re-initializing it can sometimes resolve issues.
   • Clearing the TPM might also require re-enrollment in certain security features.

6. Security Software:

   • Certain security software or third-party applications might interfere with the TPM's functionality.
   • Temporarily disable any security software and see if the issue persists.

7. Hardware Issue:

   • If you've tried the above steps and the TPM is still not detected, there might be a hardware issue with the TPM module itself.
   • Contact Dell's customer support or take the laptop to an authorized service center for diagnosis and repair.

Remember that dealing with BIOS/UEFI settings and hardware components can be sensitive, so if you're not comfortable with these steps, it's best to reach out to Dell's customer support or seek assistance from a professional technician.

@Gokul1999​ In addition to the great directions by @AdrianG001 have you accessed the BIOS (F2 immediately at boot) and confirmed that PTT is enabled?

Also this forum thread may be of some help as well.

  @AdrianG001​ When I look for tpm in the bios settings, this is what I see. When I run the command tpm.msc on the command prompt, I get a message that says " Compatible TPM cannot be found " on my system. I’m expecting your advice.Thank for the help.​

@JOcean​ I appreciate your assistance, i read it couple of days ago but I couldn’t open the back cover as I’m not skilled with hardware but I downgraded the bios but the problem persists.When I look for tpm in the bios settings, this  is what i see. 

@Gokul1999​ You do not have to open the system up at all. The settings are in the BIOS as I described (F2) and just look for PTT in the security settings.

@JOcean​ Platform Trust Technology(PTT) is already enabled. I’m expecting your advice. Thank for the help.​
