Answer 1

Hi Eddie Pardo,

I’m sorry you’re running into this with your Lenovo IdeaPad Flex 5. I can help you check whether TPM is already available on the device and, if needed, where to enable it for Windows 11. TPM 2.0 is required for Windows 11, and on some PCs it may be present but not currently enabled in UEFI/BIOS. 

To narrow this down a bit, could you let me know: 

• Are you currently using Windows 10 on this device? 
• What exact message do you see when you try to check Windows 11 compatibility? 
• Please press Windows + R to open the Run dialog, type tpm.msc, and then press Enter, do you see “TPM is ready for use”, or do you see “Compatible TPM cannot be found”? 
• If you have already entered the BIOS, do you see an option named TPM or Security Chip under Security or Advanced?  

In the meantime, please try these steps: 

1. Check TPM in Windows 

• Press Windows + R > type tpm.msc and press Enter 
• Please check what it shows TPM is ready for use or Compatible TPM cannot be found 
• If TPM is detected, please also check whether Specification Version shows 2.0. 

2. Check in Windows Security 

• Open Windows Security > Device security > look for Security processor 
• If available, open Security processor details and check the TPM version there as well.  

3. If TPM is not detected, check BIOS/UEFI 

• On Lenovo IdeaPad models, you can usually enter BIOS by restarting the PC and pressing F2 or Fn + F2 during startup.  
• Open the Security or Advanced tab 
• Look for TPM or Security Chip > set it to Enabled 
• Save the changes and restart the device.  

4. Check again after restart 

• After Windows loads again, please run tpm.msc one more time and confirm whether TPM is now detected and whether the version is 2.0.  

While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding. 

I hope these steps help you get TPM checked and enabled successfully on your Lenovo device. Wishing you a smooth transition to Windows 11 and a seamless experience with your PC.

Follow these steps in Windows 10 to enable TPM 2.0 on the Lenovo IdeaPad Flex 5 so it can run Windows 11:

1. First check if TPM is already available in Windows:
   1. Open Settings > Update & Security > Windows Security > Device security.
   2. If a Security processor section is shown, select Security processor details and check Specification version.
      • If it shows 2.0, TPM 2.0 is already enabled and meets Windows 11 requirements.
      • If it shows 1.2, the device does not meet Windows 11 TPM requirements.
   3. If Security processor is missing, TPM may be disabled in firmware; continue with the next steps.
2. Alternative TPM check via console:
   1. Press Windows key + R, type tpm.msc, and select OK.
   2. If the console reports TPM is ready for use, check Specification Version under TPM Manufacturer Information.
   3. If it says Compatible TPM cannot be found, TPM is likely disabled in firmware.
3. Enable TPM in UEFI firmware (BIOS):
   1. In Windows, go to Settings > Update & Security > Recovery.
   2. Under Advanced startup, select Restart now.
   3. On the blue screen, choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
   4. In the UEFI/BIOS menus, look under tabs such as Security, Advanced, or Trusted Computing.
   5. Enable the TPM option. On different systems it may be labeled:
      • Security Device or Security Device Support
      • TPM State
      • AMD fTPM switch / AMD PSP fTPM (for AMD-based devices)
      • Intel PTT / Intel Platform Trust Technology (for Intel-based devices)
   6. Save changes and exit firmware setup.
4. After reboot, verify TPM 2.0:
   1. Return to Settings > Update & Security > Windows Security > Device security.
   2. Confirm Security processor is present and Specification version is 2.0.

If the firmware does not expose any TPM/PTT/fTPM option, or enabling it still does not show TPM 2.0 in Windows, consult Lenovo’s support documentation for the specific IdeaPad Flex 5 model for TPM/firmware details.
