DELL Chromebook 3100 Right Side USB IO Board Ribbon Cable 30-pin D2D9P

Genuine Dell OEM Replacement Cable

This genuine Dell OEM ribbon cable carries part number D2D9P and connects the right-side USB I/O board to the motherboard in Chromebook 3100 and Chromebook 3100 2-in-1 laptops. It is the 30-pin variant used on systems that do not have the optional LTE 4G WWAN wireless module. Buyers who need the WWAN-compatible cable or a different pin count cannot use this part.

30-Pin Connector Interface Limit

The cable provides a 30-pin flat-flex connection between the I/O board and the mainboard, carrying USB and related signals for the right-side ports. It is one of two cables that attach to the I/O board, so the board will not function fully if the companion cable is missing or damaged. Systems equipped with the LTE 4G WWAN option use a different cable and are not supported by this part.

Replaces Damaged or Missing D2D9P Cable

This part replaces a torn, corroded or lost original ribbon cable to restore USB connectivity on the right side of the chassis. The upgrade is worth it when the existing cable prevents peripheral use or causes intermittent disconnects, and the laptop is a 3100 or 3100 2-in-1 without WWAN. It does not add new ports or change the USB standard supported by the board.
