Precision 5530 doesn't see TPM after TPM FW update
I've installed Dell TPM 2.0 Firmware Update Utility version 7.2.2.0, A02 (https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=419wn&oscode=wt64a&productcode=precision-15-5530-laptop) onto my Precision 5530. Update was successful, I saw it on the screen and see it in the Maintenance log in BIOS. After this update TPM module is no longer visible in the system. Neither BIOS nor Windows see it anymore. I tried to follow all recovery instructions I could find, including battery unplug / power drain cycle, but without any success.
Any idea what else I could try to bring it back to life?
No Events found!

I spent most of yesterday trying to rectify this problem with my Precision 5530, trying everything to restore TPM and the Security tabs in the BIOS and in Device Manager. Retired for the night thinking I probably needed to replace my laptop. This morning on a whim tried something I had read on the Internet about rebooting without the power cord connected, and magically, everything returned to normal on battery with TPM working again and the Security tabs restored!

Thanks! This was drinving me crazy!
Even after the newest BIOS on Precision 5530, TPM failed "randomly". Now I know why!!!!
