Dell Latitude 7290 7390 motherboard

This LA-F311P board is a direct replacement for Dell Latitude 7290 and 7390 laptops. It ships with an Intel Core i5-8350U quad-core processor running at 1.7GHz already installed. The part suits repair technicians or owners restoring a failed system to working order. It is not for buyers who want a bare board without a CPU or who need support for newer processor generations.

Build uses integrated Intel UHD Graphics 620

The motherboard relies on Intel integrated graphics and accepts DDR4 memory modules. Mounting points and connector layout match the original chassis, so the board fits without modification. Daily use means the existing heatsink, fan assembly and I/O ports align exactly as before. It is not for builders who need discrete graphics outputs or additional expansion slots beyond the factory design.

Factory-fitted i5-8350U at 1.7GHz decides

The soldered processor determines which Latitude models accept this board; supported CPUs also include i5-8250U at 1.6GHz and i7-8650U at 1.9GHz. Chipset is Intel integrated system architecture. Buyers must verify their service tag matches the 7290 or 7390 line before purchase. It is not for anyone whose unit requires a different CPU socket or chipset revision.

Questions about this item

Does the LA-F311P motherboard use a proprietary Dell interface or a standard socket for the CPU?

The board is built for the BGA soldered Intel Core i5-8350U, so the CPU is not socketed and cannot be swapped by the user.

What chassis screw-hole pattern and connector placement does the LA-F311P need to fit a Latitude 7290 or 7390?

It matches the exact mounting points and I/O cut-outs of the Latitude 7290 and 7390 chassis, including the integrated Intel UHD Graphics 620 video outputs.

Which step do installers most often miss when fitting the LA-F311P into a Latitude 7290?

Re-applying thermal paste to the i5-8350U die and the PCH, then torquing the heatsink screws in the cross pattern specified in the Dell service manual.
