HP Pavilion DV4 Screen Assembly w/ Extra antenna wires.

[jsanthara]

I recently disassembled an HP Pavilion DV4-1427nr. When I took out the LCD screen assembly I noticed not one, but two sets of antenna wires. What I am used to seeing is one set, black (main) and white (aux), and while those were present, there is another set of red (main) and blue (aux). I've taken apart more than a few DV4s and have never encountered this. I was wondering if anyone knew what the purpose of these are and maybe somewhere I could find out more information about it. I looked on different search engines, but couldn't find much. Either way, thanks for your time.

The extra antennae are for an optional WAN. This laptop may have had a spot for an optional 3G/4G mini PCI-e cellular card. It would use the same connection as the internal WiFi card.
