Right-side I/O Cable for Alienware 15 R3

This genuine Dell OEM cable connects the right-side USB I/O board to the motherboard in the Alienware 15 R3 laptop. It carries the part number M1HH9 and is also referenced as BAP10 USB BOARD CABLE or DC02C00DF00. The part is supplied new and matches the component shown in the product images. ||

Sustained signal integrity under daily use

The cable maintains a stable data and power path between the I/O board and the mainboard during continuous operation. It handles repeated insertions and normal thermal cycles inside the chassis without degrading the USB 2.0 signals that the right-side port relies on. No active electronics are present, so there is no firmware or driver dependency to manage over time. ||

Straightforward replacement with basic tools

Installation requires opening the laptop base, disconnecting the old ribbon, and seating the new cable into the motherboard and I/O board connectors. The connectors are keyed, so incorrect orientation is prevented by feel. The main risk is damaging the fragile ZIF latch or tearing the ribbon if excessive force is applied during removal.

Questions about this item

How much extra power does the M1HH9 cable draw when the laptop runs all day?

The cable is a passive ribbon that carries signals only; it adds no measurable power draw to the system.

Which board must already be present in the Alienware 15 R3 for this cable to function?

The right-side USB I/O board (sometimes called the databoard) must be installed so the M1HH9 can connect it to the motherboard.

Will the M1HH9 cable fit an Alienware 15 R2 or earlier model?

No — the part is listed as compatible only with the Alienware 15 R3, so older chassis use a different cable.
