It's in the chip.
This video at around the 50 second mark says laptops do not have to be
connected to a network and can still be disabled remotely. How?

"Disable lost or stolen laptops, even if the PC is not connected to the
network." (With a superscript 8) There is a footnote at the end of the video.
"...Requires an enabled chipset, BIOS, firmware, and software..." Strangely
it says nothing about hardware. Also needs a "...subscription to a capable
service provider..."
List of providers

"Intel® Anti-Theft Technology is an intelligent way for you to help secure
the mobile assets of your workforce. This intelligent security technology is
available on 4 generations of laptops based on Intel® Core™ and Intel®
Core™ vPro™ processor families. This technology is built into the
processor, so this will be activated even before the laptops startup and will
work even without internet as it is hardwired and it is completely tamper
proof."

Looking at several of the companies on intels service provider list is very
interesting. Way lots of control so to speak.
Who's to say that like the onStar non-subscribers who are still being
tracked, that something similar is not available on laptops to the right
people or agencies?
