Inspiron 5415, TPM not working
I recently bought an Inspiron 14 5415 [AMD Ryzen 5 5500U and when I opened a software I noticed it said that TPM 2.0 is required/not found or something.
It seems that I may not have the TPM hardware* but I am slightly confused since I read that for windows 11 to work (which I am on) you need something that supports TPM 2.0?
Also there is an option in the BIOS UFEI settings that shows firmware TPM but it is greyed out and I can’t enable it? I am able to enable secure boot however (don’t know if that’s relevant)
I’m not very knowledgeable about laptops or specifications but I’ve been searching online a lot but found nothing useful.
Anyone know anything? Or can confirm that I ultimately do not have TPM at all and what would be the alternative for my laptop to be running on instead since I also cannot find an option for PTT either?

TPM 2.0 is not present in device manager

The issue with this is that my BIOS does not look like that since the fTPM option is greyed out and the only other options I have for security are shown in the picture. I’m not sure how to make it available or if I even can?

Same here, Dell should have clear instructions on the combination of steps to enable fTPM that is baked into the Ryzen CPU Particularly as they advertise the device as Windows 11 compatible and it clearly it is not with the OOB configuration.

In the BIOS- Security, Enable the first Absolute. Then see if Firmware TPM can be Enabled.

Some just put random article, which is not relevant at all. That video is of a desktop computer, with gigabyte motherboard. If you could post something that is on Dell Amd based system, that will be be helpful

Hi, I have a similar issue: https://www.dell.com/community/Inspiron/How-to-enable-Firmware-TPM-on-Inspiron-5515-BIOS/m-p/8124300#M136187
Did this ever get solved?

Unfortunately not yet, I've been informed that my model was not shipped with TPM but then I'm not entirely sure how windows 11 was installed and what alternatives would be present since I can't find a PTT option and fTPM cannot be enabled? My UEFI settings look exactly like yours and even after enabling Absolute the option didn't become available. Not sure why yours didn't come installed with windows 11?
I found this article which is interesting:
Windows 11 – Scope of Support and System Requirements | Dell UKIt does say that the requirements for windows 11 is 'Firmware and hardware TPM that support TPM standard 2.0' which makes me think that there is some sort of component in my laptop that can support windows 11 but not sure what that would be?
Seems like Dell pre-install windows 11 on some laptops that don't meet the hardware requirements? So I'm assuming that's why the laptop I bought about a month ago can run windows 11 but your model cannot. Not sure why they do this as since it makes troubleshooting more difficult and not able to be supported. Next time I'll be sure to check the specifications specifically for TPM 2.0 support.
Either way seems very inconvenient since all I see is that TPM is a requirement for most laptops made after 2016 which I would assume my laptop was.

Tried it on a dell Inspiron 5415 (purchased November 2021) and it does not work even with the latest BIOS 1.7.1
I have also opened a ticket and been told my machine does not come with a TPM. (while my ticket was about fTPM enabling not being visible and the AMD CPU has an fTPM baked in)
Lucky enough my one is still in warranty so I might return it as it is not compatible with windows 11 as stated in the compatibility page.

Dell will have to deal with the upcoming changes to put a watermark on unsupported devices https://www.engadget.com/windows-11-watermark-unsupported-hardware-135550376.html

This video may help. You need to enable AMD fTPM in security settings.
