Explanation
It is standard practice to route the wireless NIC's antenna wires through the laptop lid and around the edges of the LCD panel. This placement maximizes signal reception by keeping the antennas as far from the metal chassis (which blocks RF signals) as possible. These thin coaxial wires are commonly mistaken for something else during repairs. They are not EMI shielding (A), Bluetooth wiring routed this way would be uncommon (B), and discrete high-performance video cards are not found inside laptop lids (D).
