So, to be clear, you&#x27;re saying modern processors can no longer be physically plugged into a motherboard? That the processor and BIOS chip are physically too big to be isolated into a card-sized container that plugs into such a slot on a laptop? Everything else, including cooling, could be built into laptop part. But this critical part is impossible with today&#x27;s technology and they all have to be hardwired at manufacturing?<p>It&#x27;s strange because my friend&#x27;s desktop CPU fit into my hand and plugged into place. That was a year or two ago. If that&#x27;s no longer possible, though, then the CPU can&#x27;t be extracted into its own device and my scheme can&#x27;t apply.
