Whats missing P570WM

[Mofe]

advice on whats missing in my system?

Nothing really.

1 - Seems to be a USB connector for camera/3d display (probably for different laptop models)

2 - Seems to be some kind of debugging port. Lot's of motherboards have them, sometimes unpopulated (with no connector)

3 - Seems like a connector for a bluetooth module judging by location and the BT label on the cable. Probably USB as well

4 - Third WI-FI antenna. Only used with 3-antenna WI-FI modules.

You're not missing anything. Different laptop models often share the same motherboard, so some models will have certain ports populated, others not.
