Genuine Dell IO Board for Inspiron 5401
This genuine Dell OEM circuit board restores the USB port, SD card reader and audio jack on an Inspiron 5401 laptop. It arrives new and matches the factory part number 3XKGT. The component is intended for technicians or owners repairing a damaged I/O assembly.
Fits directly into the Inspiron 5401 chassis
The board slots into the existing cut-outs without modification and reconnects to the mainboard through the original ribbon cable. It consolidates three peripheral interfaces on one module, freeing the user from external dongles for USB, card reading or headset use.
Maintains connectivity during extended sessions
Under sustained data transfer or continuous audio playback the factory-spec traces and shielding preserve signal integrity. The part is rated for the thermal and electrical envelope of the original design, so it does not degrade when the laptop runs at full load for long periods.

Questions about this item
Will the SD card reader on this IO board keep working during long file transfers without overheating?
The board integrates the SD card reader, USB port and audio jack on a single circuit; sustained use stays within normal laptop thermal limits.
Does the board add any fan noise or extra power draw when the USB port is used continuously?
It draws power from the mainboard like the original part and has no active cooling, so it adds no audible noise or measurable extra load.
My Inspiron 5401 motherboard is intact — do I need any other parts to install this 3XKGT board?
Only the board itself is required; it connects directly to the existing motherboard header and reuses the chassis cut-outs for the USB, audio and SD slots.
