XPS 15 9560, Alert! TPM device is not detected
Having followed these steps & those provided on the Dell support page, I'm still receiving an error during bootup "Alert! TPM device is not detected."
The TPM is not visible in the bios or Windows device manager.
Installing V2.0 firmware was not successful.
TPM Management states, "Compatible TPM cannot be found".
Bios has been updated to the current version.
My warranty has just conveniently lapsed & not service agents are available until tomorrow.
I've even tried to pay for further support & warranty extension, but to no avail.
What now Dell?

I too had this problem for a long time on several computers at work but managed to solve it.
During my quest to find a solution I tried everything but it never occurred to me that I never shut down my computer and unplugged to power cord. I have always shut it down with the power cord still in, just restarted the computer or have it gone in sleep mode. I bet most corporate do this using sleep mode or have the AC plugged in when shut down.
Well how stupid did I feel when I shut down my computer completely, unplugged it from the AC and let it be for 30 second. When I plugged in the AC again and turned on the computer the magic happened. LOL The TPM alert was gone. For some reason shutting down the computer and unplugging the AC for 30 seconds seems to do something allowing the bios to find the tpm again.
So I tried the same on a second computer and the same stupid fix worked on that one. Well in the end we did this on all the computers encountering this and the same fix applied for all of them. So after this we are now upgrading the bios on all computers and any computer getting this error is easily fixed by shutting it down, removing the AC for 30 second and then firing up again. lol
So if you havent tried this then please try it and see if it works for you. Im not saying it is the fix but worth trying
Need further assistance? Use the "Get Help Now" option at the bottom right to chat with a Dell technician right away.

My error is not due to a bios update. I cannot roll it back as I have not updated it.
I will note that my bios version is listed as 10.0.18362.1 & not 1.15 as is referenced in the linked thread.
As an experiment, I just updated to 1.16 to see what would happen when I rolled back. No help. Rolled back to 10.0.18362.1
Should I be looking for a way to source 1.15?

I updated to the new 1.80 bios and I have the same issue. Going to roll back my bios to one that did not have this issue.

Not that this is an option for everyone but luckily the laptop was still under warranty and a motherboard swap did the trick for me. TPM showed up in BIOS and works in Windows.
Best of luck.

Hi,
Could you type tpm.msc in run command & check the status of TPM. Let me know if it says TPM ready for use.

Exactly the same computer and same BIOS issue. Rolled back to 1.15. I was hoping that 1.18 would fix it. I guess they want us to buy new machines.

This is very annoying. I have a Precision that I spent almost $3k on and having the same problem. Does Dell put these BIOS update through adequate testing? Does not appear to be the case.

For me it has always been the case. I have had multiple (+10) Latitudes with TPM gone missing after a BIOS update. So far, Dell has always replaced the motherboard.
