Genuine OEM Latitude 5280 Motherboard

This genuine Dell Latitude 5280 motherboard carries part number 4T711 and integrates an Intel Core i5-7300U processor with a 2.60 GHz base clock. It uses a BGA 1356 socket and includes HD Graphics 620 for integrated video output. The board is supplied new and is intended as a direct replacement for the same chassis.

Suits owners repairing a Latitude 5280

Technicians replacing a failed system board in a Latitude 5280 will find the correct mounting points and connector layout. The soldered BGA 1356 package means the CPU cannot be swapped, so this part is not suitable for anyone wanting a socketed upgrade path or a different processor generation.

BGA 1356 socket locks the CPU

The single specification that decides fitment is the BGA 1356 socket, which permanently attaches the Core i5-7300U to the board. Memory slots accept DDR4 modules, but the processor itself is not removable. Verify the 4T711 part number against your service tag before ordering.

Questions about this item

Will the BGA 1356 socket on this 4T711 board fit the existing chassis of my Latitude 5280?

Yes, this motherboard is built to the exact Latitude 5280 form factor so the BGA 1356 layout aligns with the original mounting points and port cut-outs.

Which step do installers most often skip when fitting the Core i5-7300U board into a 5280?

Re-applying thermal paste on the soldered CPU die and GPU 620 heat-sink contact before reassembly is the step most frequently missed.

What component will likely need replacement first on a 2.60 GHz 7300U system board?

The CMOS coin cell is the only routine maintenance item; the soldered processor and DDR4 slots are not user-replaceable.
