Hi

When I enter my S/N (CS00357751), this Lenovo web page thinks I have a desktop but I have a laptop. It has ThinkPad on it but it's product family is C540 and machine type 6267. It is running Windows 11 Home version 22H2 and I want to update it to version 24H2. I have tried the standard windows update but it doesn't work. I have tried to run various things suggested by Microsoft and none work. In the course of trying I accessed the BIOS and TPM is enabled but it says I do not have a compatible TPM. How can this laptop run Windows 11 Home version 22H2 without a compatible TPM? More importantly, how can I get a TPM 2? Is it to do with the hardware and so beyond me or is it a software upgrade?

Kind regards,

Moira

Hi Moira,

Thank you for reaching out to the Lenovo Community!

I understand your concern regarding the TPM compatibility and the update to Windows 11 version 24H2. Let's address your queries step-by-step:

Identifying Your Device

It seems there might be some confusion with the product identification. The ThinkPad C540 with machine type 6267 is indeed a desktop model. However, if you have a laptop, please double-check the model number and serial number. You can use the Lenovo Product Specifications Reference (PSREF) to verify your device details.

TPM Compatibility

Windows 11 requires TPM 2.0 for installation and updates. If your BIOS indicates that TPM is enabled but not compatible, it might be that your device has TPM 1.2, which is not sufficient for the latest Windows 11 updates.

Steps to Resolve TPM Issue

1. Check BIOS Settings:

   • Restart your laptop and enter the BIOS setup (usually by pressing F1 or F2 during startup).
   • Navigate to the Security tab and check the TPM settings.
   • Ensure that TPM is enabled and set to TPM 2.0 if available.

2. Firmware Update:

   • Sometimes, a BIOS update can enable TPM 2.0 support. Visit the Lenovo Support Website and check for any available BIOS updates for your model.

3. Lenovo Vantage:

   • Download and install the Lenovo Vantage App. This tool can help you manage system updates and check for any firmware updates that might enable TPM 2.0.

If TPM 2.0 is Not Available

If your device hardware does not support TPM 2.0, it might not be possible to upgrade to Windows 11 version 24H2. In such cases, you may need to consider hardware upgrades or consult with an authorized service center.

Additional Support

If you continue to face issues, I recommend contacting Lenovo Support directly for further assistance. You can submit a service request here or find an Authorized Service Center near you.

I hope this helps! If you have any further questions, feel free to ask.
