DELL Precision 7760 Ribbon Cable Palmrest USH Junction Board A20AL7

Genuine Dell OEM Replacement Part

This is a genuine Dell OEM ribbon cable designed specifically for the Precision 7760 laptop. It connects the palmrest USH junction board directly to the motherboard. The part carries Dell part number A20AL7 with alternate references GDB70 and NBX0002SH00. It is intended for technicians or owners repairing this specific model.

Reliable Signal Integrity Under Daily Use

The cable maintains a stable connection between the palmrest security module and the mainboard during continuous operation. As a fixed internal flex assembly, it is built to endure repeated thermal cycles and mechanical stress from regular lid opening and closing. No active components or power regulation are present on the cable itself.

Direct Substitute for Damaged Original Cable

This ribbon cable replaces a torn, corroded or loose factory cable that causes USH fingerprint reader or palmrest button failures. The repair is worth it when diagnostics confirm a physical interconnect fault rather than a motherboard or module defect. It does not upgrade functionality or add features absent from the original design.
