Genuine Dell OEM rear I/O cable

This genuine Dell OEM cable connects the rear I/O daughterboard to the motherboard on Alienware m16 R1 and m18 R1 laptops. It carries the USB and SD card reader signals for the rear ports. The part number is H0CHC and you receive the cable only.

Installation requires laptop disassembly

Fitting this cable means opening the chassis to reach the motherboard and rear I/O board connectors. The routing is tight and the connectors are small, so work slowly and keep track of screw lengths. The usual problem is damaging the fragile header pins or pinching the cable when reassembling the case.

For owners with failed rear ports

This part suits anyone whose Alienware m16 R1, m18 R1, m16 R1 AMD, m18 R1 AMD or m18 R2 has lost rear USB or SD card function due to a damaged cable. It will not help if the fault lies on the motherboard or the I/O board itself, and it does not fit other laptop models.
