It sounds like your laptop has a different type of connection than what you're used to. The processor is directly attached to the motherboard without a socket, which is common in some modern systems. This setup means the CPU is physically connected through the motherboard, not via a PCIe slot. Let me know if you'd like more details!

It's a BGA component, directly attached to the PCB. Removing it requires costly tools. For more details, see this article: https://en.wikipedia.org/wiki/Ball_grid_array

It was attached to the motherboard to minimize dimensions from the holding system and simply for added thickness.

Instead of a large, heavy socket with pins, the CPU pads receive a small amount of solder. A bit of hot air melts the solder onto the pads attached to the motherboard. The solder is strong enough to securely fasten the CPU and substrate to the board.

Varies by laptop model; some use PGA or LGA sockets, others BGA soldering. If your laptop is more than eight years old, it likely has a socketed CPU, while newer models usually feature BGA. The last Intel laptops with LGA were the fourth generation.
