Internal I/O board for Alienware M18x

This card reader board replaces the original I/O circuit board in Dell Alienware M18x laptops. It restores the ExpressCard slot and SD card reader alongside the HDMI and eSATA connectors. The part carries Dell part number TPK3N and is supplied in new condition.

Repair technicians and owners of the M18x

The board suits anyone repairing a damaged I/O daughterboard on an Alienware M18x. It will not fit other laptop models, and it does not add functions that the original chassis does not already support. Builders working on different platforms should source the correct board for their machine.

ExpressCard and SD card reader integrated

The single specification that decides compatibility is the presence of the combined ExpressCard slot and SD card reader on this TPK3N board. If the failed unit in the M18x lacks either interface, this part will not match the original layout.

Questions about this item

What interface does the ExpressCard slot on this TPK3N board use and what throughput does it cap at?

The ExpressCard slot uses the PCIe interface; its practical cap depends on the Alienware M18x chipset generation.

What physical space and connectors does this board need to fit inside the laptop?

It mounts in the M18x chassis cut-out and connects to the motherboard via its dedicated ribbon-header.

How is the board installed and which step do people often get wrong?

Remove the bottom cover, disconnect the old board ribbon, seat the new board, reconnect the ribbon, and do not forget the tiny grounding screw.
