G15 5515 Ryzen edition.TPM not detected in windows 11
TPM enabled in bios, seeing fTPM on initial EFI screen.
Not seeing a line in the device manager for security devices for fTPM
Windows is at 21H2 and will not update as it's can't see TPM enabled.
Seeing this in 2 laptops, one on bios 1.16, other updated to latest bios 1.24.
Anyone had this issue and worked out solution.

Is the system running in UEFI mode, or is Legacy (CSM) mode on (check setup -- F2 at powerup)?

I am wondering if this has been caused by a upgrade I carried out where I fitted a larger drive, I cloned the original and put a 1G in. This was done on both laptops, I will swap back to the original drives to see if this resolved.

Further to this, that hasn't resolved,I am starting to wonder if a TPM is actually present and DELL circumvented the original installation of Windows 11, or their bios updates have corrupted the key. Having 2 identical laptops with the same issue suggests a common factor.
Luckily I have found out a new way to install the latest version of Windows 11 using the windows media creation tool which requires no hacks no registry changes, this did the update keeping all the settings and apps. I have upgraded one laptop and thats up to date now. Now doing the second one. I may contact Dell and ask what is going on

@Sadbiker I've been waiting for my child's exam period to finish to upgrade their G115 5515 Ryzen Edition to windows 11, but being told that TPM 2.0 is not present. I've enabled Firmware TPM in the bios (after updating to the latest bios) but TPM is still absent. Did you manage to find a solution, I'm at the very limits of my technical knowledge and any help would be appreciated. Thanks.
