Sorry for the late reply.. do a search in EC for ActiveRegn, it will have "Nvram" before it. clear from the words ActiveRegn to the end of the data (when it starts back to a block of FF)

i have since found a youtube video by Borvi Tech called "Hp EliteBook 840 G8 Bios Unlock Step by Step 100% Free" where he shows graphically how to do it about 22 minutes into the video on a G8.

be sure to get a back up bin copy first, not sure what other ramifications this procedure has....
