Hello everyone,

I's been more than a year that I'm seeing this error every time I turn my Laptop on. Nothing from Dell's recommendations worked, also I have tried to downgrade/update the BIOS with no luck.

As I see from community's discussion Dell recommends to replace the motherboard in this case.

But has anyone tried to replace the TPM chip itself on the motherboard with the working one? Is that possible?

Also is that possible to replace the 5480 motherboard with 5491's one with the next gen CPU?

Thanks in advance.
