I had the same problem with a 7040. For me, the TPM option was weirdly buried under "Security > PTT" in the BIOS, not labeled as TPM.

You could also try updating the BIOS to the latest version from Dell's support site, as that can sometimes enable the proper TPM support. Let me know if that works.

Yeah, that's a solid suggestion. Also, double-check that the TPM isn't hidden under a weird name like "Intel PTT" or "AMD fTPM" in your BIOS settings. Hope that helps.

Can confirm. And just to be sure, is your BIOS itself fully updated? Sometimes that unlocks the setting.

Yeah, that's a good call. Also, double-check that the TPM isn't hidden under a weird sub-menu like "PTT" or "Security Device" in your BIOS. Hope that helps.
