Alert! TPM device is not detected.

Question

Hi, I have a Dell Inspiron 3501 laptop with an 11th Gen Intel Core i5-1135G7 processor, which I bought 1.6 years ago. A few days ago, I installed some critical updates from Windows, including the BIOS update 1.25. Since then, I get an alert saying “TPM device is not detected” every time I turn on my system, and it also asks me for the Bitlocker recovery key frequently. Moreover, I cannot shut down my PC normally; it goes into sleep mode instead. I have to enter boot manager to turn on my system.

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.

Can anyone please help me with this issue? I would appreciate any advice or suggestions. Thank you in advance.

Steps to Check if Your System Has a TPM Chip

Before you start troubleshooting, make sure your system has a TPM chip. Here are three ways to do this:

Using TPM Management Tool:
- Press Windows + R to open the Run dialog box.
- Type tpm.msc and press Enter.
- In the TPM Management window, check the Status section. If it says "The TPM is ready for use," your system has a TPM chip. You can also check the Specification Version under the TPM Manufacturer Information section to see if it is version 2.0.
Using Device Manager:
- Press Windows + X and select Device Manager.
- Expand the Security devices section.
- Look for Trusted Platform Module. If it is listed, your system has a TPM chip.
Using BIOS/UEFI:
- Restart your computer and enter the BIOS/UEFI settings (usually by pressing F2, Delete, or Esc during startup).
- Navigate to the Security or Advanced tab.
- Look for an option related to TPM, such as Trusted Platform Module, TPM Support, or fTPM. If it is listed, your system has a TPM chip.

Steps to Enable TPM

If your system has a TPM chip, proceed to the next steps:

Update BIOS:
- Visit the Dell Support website and download the latest BIOS update for your Inspiron 5515.
- Follow the instructions provided to update your BIOS.
Enable TPM in BIOS/UEFI:
- Restart your laptop and press F2 (or the appropriate key for your system) to enter the BIOS setup.
- Navigate to the Security or Advanced tab.
- Look for an option related to TPM, such as Trusted Platform Module, TPM Support, Intel PTT (Platform Trust Technology), or AMD fTPM.
- Enable the TPM option if it is available.
- Save the changes and exit the BIOS setup.

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:

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.
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.
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.
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.
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.
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.
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.

@DELL-Jesse L​ 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?

@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.

Gokul1999 · Answer

@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.

JOcean · Answer

@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.

Gokul1999 · Answer

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

@AdrianG001​ Hi How you supposed to connect or disconnect a TPM module on a XPS 17?

BrianEV · Answer

@DELL-Nat M​ I have the problem and can only startup by seeing the alert screen and pressing F1. Following the diagnostic advice, I see no indication of a TPM device. If there isn't one, can I do something to avoid the necessity of seeing the alert screen?
