    is CMOS (since it works as clock) the only hardware that's active when fully shut down/ totally unplugged/ even without power/ adapter// laptop battery usage? or is there any other hardware?
    from security POV
    even if something does, theoretically dissembling hardware should force it to be inactive, completely shut right?

    Yes CMOS works as Clock and it is the only hardware that's active since there is a battery when shut down/ totally unplugged/ even without power/ adapter// laptop battery usage and there is no other Hardware.
    No dissembling hardware won´t force it to be inactive.

    The only way to force it to completely shut is to remove the CMOS from the motherboard normally CMOS is integrated in the BIOS chip.

    CMOS (Complimentary Metal Oxide Semiconductor) is a chip (Integrated Circuit) fabrication process. CMOS ICs consume very little power.

    With that said, the MoBo has a clock, which will keep on running even if the MoBo is removed from the PC.
    There is a battery on your MoBo. It provides power for the CMOS clock and RAM (CMOS RAM holds information used by the BIOS)
    removing it will reset the clock and the CMOS RAM.
