Question "Alert! TPM device is not connected" error after doing latest windows update - Dell XPS 13 9360

[militarydave]

Hello,

This afternoon after using my Dell XPS 13 (9360) as I normally do - for school It did an update that took way longer than normal (almost 20 minutes). It rebooted fine and I used it for about an hour then shut it down. Drove home a few hours later and turned it on and I get an "Alert! TPM Device Not Detected" error. The only options are to continue, boot device, and BitLocker recovery.

I don't have a key for Bitlocker and even I uninstalled the latest update via the advanced options when I selected "Skip this Drive", I get the same error. The only other information I found about this error on Dell XPS was to unplug the AC cord for 30 seconds and plug it in. Obviosly power-cycling did not work.


Anyone know how I can boot past this?


V/R,
Militarydave

Yeah this was the whole "disconnect the a/c plug for 30 seconds" trick that did not work for me. I watched the video but I cannot upgrade or rest the TPM as I cannot access the desktop. I'll try resetting the Bios or try to get the recovery key from BitLocker.

I would check to see if tmp is an option in the bios. You can typically disable it on UEFI.

Unfortunately, it is not an option on the Bios. It upgraded to Bios 2.16

Is that one the models that will let update TMP with Dell command update tool?

Try to downgrade your bios to 2.10, I allways got the same trouble on my XPS 13 9360 with higher bios numbers. 2.10 seems the highest number for me without this problem.
