Alert! TPM device is not detected. Dell laptop. Removed AC Power for 30 sec. Turned on Laptop

Disclaimer: Boring Video.

I received this error recently on my dell laptop.

HEADLESS OPERATION ACTIVE
Alert! TPM device is not detected.

It would not allow me to boot into the windows 10 OS.
1. I tried this:

2. I read this...

3. Finally, in part of this forum, it mentions removing the power and waiting 30 seconds. This worked for me:

Good luck. I'm not sure what solution will work for you.. but I hope you don't run into this error.
