XPS 15 9570, TPM device not detected
I've gotten a critical alert a couple of times over the past few days that the TPM device wasn't detected during startup. It's happening intermittently. I checked the TPM Module 2.0 in the Device Manager and it states it's working properly. Windows Update indicates that I have the most recent version of the driver. This is on an XPS 15 9570 running Windows 11 Home.

I have the same machine so it suggests Windows is mangled bad, so I suggest a fresh install of Windows 11

Mam podobną sytuację z XPS 15 9560, u mnie komunikat pojawia się na poziomie BIOS, po wciśnieciu kontynuacji wszystko jest OK, tylko już nie mam aktualizacji windowsa. W BIOS niema zakładki TPM, do czasu zniknięcia TPM wszystko było OK.
I have a similar situation with XPS 15 9560, for me the message appears at the BIOS level, after pressing continue everything is OK, but I don't have windows updates anymore. There is no TPM tab in the BIOS, everything was OK until TPM disappeared.

I had this issue today an hour ago on my XPS 15 9570 with a new motherboard with the i9-8950HK from early June 2025 when my original i7-8750H motherboard died on May 28, 2025 due to the capacitor burning down and also burn whatever was right under the F5 key.
Before this, I held down power button for 25 seconds to reset the RTC CMOS which did not fix the problem.
The way I fixed it didn't involve opening up the computer.
I saw in the XPS 15 9560 thread here:
https://www.dell.com/community/en/conversations/xps/xps-15-9560-alert-tpm-device-is-not-detected/647f8477f4ccf8a8de357c51?commentId=6605e821d478b1269a47496c
Where it says:
1) Unplug AC Adapter cable, wait 1 minute
2) Hold down Ctrl+ESC while plugging the AC Adapter back in and system should turn on itself
3) It will show a BIOS Recovery Menu
4) Select reset bios back to default
In my case, I didn't do step 4 because I tried to memorize the post and instead select Cancel and it fixed it. #4 might be the correct choice.
This brought back the missing TPM setting under Security in the BIOS.
