The system likely uses Intel PTT, not a true TPM.  As long as it wasn't originally sold in a part of the world where such technology is banned (China, Russia, parts of the Middle East), you enable it as follows: [URL]
Hello I tried almost everything possible to get back TPM option into dell vostro (win 10 64 bit), but nothing helped:Tried turn off pc, unplug for more than 30 secs, plug back cable, go to bios to check if it is back - no it wasn't. Also tried to download TPM 2.0 updater, but after running it, it returned me error. When I checked in bios I have there UEFI not Legacy mode.When I win + R and run TPM.msc it gives me: Compatible TPM cannot be found. It annoys me because always when I turn on computer it shows me screen with Alert. that TPM is not found, so it not boot/load system until I won't press continue. Is there is a possible way how to get it back into bios and then enable it?My premium support/warranty is expired, so I am trying to fix it by myself - if it is even possible.
TPM is missing in bios settings (in security)
