Genuine Dell IO Board K120P

This genuine Dell replacement right-side IO circuit board integrates the power button, USB jacks, audio ports and an RJ-45 connector. It also houses the wireless catcher switch and indicator LED. The part connects directly to the motherboard and is built for the Latitude E6500 and Precision M4400 laptops. Ribbon cables are not included with the board.

Compatibility limited to Latitude E6500

The single specification that decides fit is the exact laptop model: this board only works with the Dell Latitude E6500 and Precision M4400. It will not install in any other chassis or generation. Buyers who need a replacement for a different Dell series must source the correct part number for that specific model.

Passive component with no active cooling

The board draws minimal power from the motherboard and produces no measurable heat or noise during normal operation. It contains no fan or moving parts, so thermals and acoustics are entirely dependent on the host laptop's own cooling system. Power consumption is negligible compared to the main system components.
