Hey I was just messing around with my hp and was just curious as too what do number 5 and 6 (wires) do exactly? I know the 2 white wires are connected for the wifi chip. Are the black ones numberd 5*6 just extras??
Can't be 100% sure, but if there are two extra antenna wires in there, they would most likely be for the optional WWAN card used in conjunction with a SIM card to connect to cellular service.
If I am correct, there should be an empty slot near those antennas for a WWAN card to go, and your notebook should have a SIM card slot somewhere.
Consult your specific model Probook's service manual for more information.
