Replacement Motherboard for Inspiron 14 5410

This Dell motherboard carries the TX40J part number and fits the Inspiron 14 5410 2-in-1 series. It arrives with an Intel Core i5-1135G7 processor already mounted, running at 2.40 GHz with a 4.20 GHz maximum turbo frequency. The board is new and intended for repair or upgrade of a compatible laptop chassis.

Direct Swap for Failed TX40J Boards

The part replaces any TX40J, 0TX40J or CN-0TX40J motherboard and matches the compatible numbers 03P8J and 4550N8010002 listed by the supplier. It is the correct choice when the original board has failed and the part number on the old unit matches one of those identifiers. Buyers who need a different form factor or a socketed CPU for future upgrades cannot use this fixed-processor design.

Sustained Operation with Soldered i5-1135G7

Because the processor is soldered, thermal performance depends entirely on the laptop's original cooling assembly and fan curves. The i5-1135G7 will hold its 4.20 GHz turbo only while power and temperature limits allow, then settle to a lower steady-state clock during extended workloads. The board supports up to 16 GB of DDR4 memory at 3200 MHz across two slots, so memory capacity is capped at that level.

Questions about this item

What chassis does the TX40J motherboard fit?

The TX40J motherboard fits the Dell Inspiron 14 5410 2-in-1 series chassis. Verify your original part number matches TX40J, 0TX40J, CN-0TX40J, 03P8J, 4550N8010002, 455.0N801.0002, 203071-1, 003P8J, or CN-003P8J before ordering.

Which screw or connector step is most often missed when installing the TX40J board?

Reconnect both the display cable and the 2-in-1 hinge sensor cable before securing the board; missing either prevents the touchscreen and rotation features from working.

How much DDR4 memory can the TX40J board support later?

The board supports up to 16 GB of DDR4 3200 MHz memory across its two slots.
