Genuine Dell OEM ribbon cable for Precision 7670

This genuine Dell OEM ribbon cable carries part number 4R5RV and connects the power button board in the Precision 7670 laptop. It is a direct replacement for the original flex cable that routes the power switch signal to the motherboard. The part is listed under alternate numbers HDC50 and NBX0002ZN00. Buyers who need a different connector layout or a cable for another model cannot use this item.

Thin flexible circuit with board-to-board connectors

The flat ribbon uses a narrow flexible circuit that fits inside the Precision 7670 chassis without interfering with nearby components. Its board-to-board connectors snap onto the power button board and the mainboard, so installation requires only careful alignment and gentle pressure. The cable is supplied new and matches the factory routing, meaning no adapter or modification is needed during reassembly.
