Genuine Dell OEM Keyboard MCU Cable

This genuine Dell OEM ribbon cable carries the part number 0R49W and connects the MCU junction board to the motherboard inside compatible Alienware x15 laptops. It fits the Alienware x15 R1 and Alienware x15 R2 models exactly as shown in the supplied image.

Flexible Flat Cable Interface Limits
