I've had the same experience with my XPS 9560. Past few years I've had "TPM device is not detected"[1] issues. Tried all the different solutions and nothings fixed it. Dell have never addressed it with a BIOS update. I don't want to go back to OS X, but its hard to find good build quality and a high res screen. Also, my battery was terrible after a couple of years. I had it plugged in as well. I bought a replacement this year and it was easy enough to switch out. Hopefully I can just keep this going and use it as an RDP machine.

I had the same issue, for me updating the TPM firmware solved the issue (but it is convoluted) https://superuser.com/questions/1668861/alert-tpm-device-is-not-detected-on-dell-laptop-boot https://superuser.com/questions/1668861/alert-tpm-device-is-... My guess is that Dell didn't update the TPM firware, my guess is this breaks some keys so can't be done automatically and a BIOS update at some point then screws up the handshake with the older TPM firmware unless the laptop is fully powered off. But I'm not a huge fan of dell hardware.
