Hi,

We are having issues with several 5480 laptops giving the error "Alert! TPM device is not detected" on start up.

This has started on all these laptops after updating the bios to the latest version. 

We have tried many troubleshooting techniques but nothing shows in the bios settings to disable/enable it, TPM cant be found with in the windows utility and PowerShell says "The Device Is Not Ready" when running any TPM related command

If anyone has a fix for this or Dell can fix this issue in the next BIOS update that would be appreciated. 

Many Thanks
