DELL XPS 9560 TPM not available

Hello, I think my TPM chip of my XPS 9560 is broken, cause it is not more available in the bios. I noticed something was wrong, after i had to enter my Bitlocker key everytime I started Windows 10 1903. After a format and a reinstall of my OS, i cannot enable bitlocker anymore and get the warning: "This device can't use a Trusted Platform Module. Your administrator must set the "Allow Bitlocker without a compatible TPM" option in the "Require additional authentication at startup" policy of OS volumes". I never had this warning before. I also noticed that the TPM option is no more availeble in my BIOS under "Security". The strange thing is, that this suddenly disappeared. I did not had a bios update or somithing. I tried to fixed it, by updating my bios from 1.15 to 1.16. But now during booting of my Laptop, i get a alert with: "Alert! TPM device is not detected". So to get rid of the warning I downgrade the bios back to 1.15. But still the TPM is not availeble. Does this mean my TPM chip is broken, or is Dell aware of this problem? If my TPM chip is broken, can the alert be disabled?

What version of windows 10 do you have--Home, Pro or Enterprise? Did you reinstall the correct version? Home does not have bitlocker and comes on most new computers. Make sure you did not install that if you originally had Pro.

Hi there, I installed the pro version, created from the dell os recovery tool. So it is the correct one.

Re: DELL XPS 9560 TPM not available

The TPM on my XPS 9560 disappeared a while back, maybe sometime last year. I forgot the exact details but I had problems with Bitlocker not finding the TPM and the TPM option had disappeared from the BIOS configuration menu.

I setup Bitlocker to use a password at startup instead of TPM and that has been working fine for me.

However this morning I upgraded the BIOS from 1.15.0 to 1.16.0 after being prompted by Support Assist but afterwards had the same BIOS message at start-up "Alert! TPM device is not detected".

I downgraded to 1.15.0 and the message has stopped.

I am not particularly concerned about the "loss" of the TPM, but I would like to now is there a way to disable the check to get rid of the message.

Hi There,

If is setup bitlocker with a password, does this mean I have to enter the password, everytime I boot up my Windows?

I'm having the same issue. I haven't found any solution beside rolling back. I created a case with Dell, but was closed due to my laptop is out of warranty and I'm overseas.

Same here with Firmware 1.16 Update. I had to downgrade to 1.15.

You don't have to run it from a USB boot.

Download XPS_15_9560_1.15.0.exe and save it where administrator can access it (for example: Public Downloads).

Log on as admin and run it from within Windows (10 Home for me). The same way you normally do. Follow the instructions ("Don't turn off the power etc..").

The error warning's gone but you get the update notification back in Windows instead. You have to click "Remind me later".
