DELL LA-F322P Motherboard i3-7130U 2.7GHz accessory

SKU CH-MQXP-454AC MPN LA-F322P

Replacement laptop motherboard with Intel Core i3-7130U processor for Dell Latitude 7490

  • Direct replacement for Dell Latitude 7490 systems
  • Intel Core i3-7130U dual-core processor at 2.7 GHz
  • Supports up to 32 GB DDR4 memory
  • M.2 2280 slot accepts SATA and PCIe SSDs
  • Integrated Intel HD Graphics 620 for 4K output

Dell Latitude 7490 replacement motherboard

This new LA-F322P board is built for Dell Latitude 7490 laptops that need a direct swap. It arrives with an Intel Core i3-7130U dual-core processor already soldered in place, running at 2.7 GHz with 3 MB SmartCache and a 15 W TDP. Technicians restoring a failed system or upgrading from a slower CPU can install it without reballing or firmware changes.

Thermals and power in daily use

The 15 W TDP keeps heat output modest, so the existing Latitude 7490 cooling assembly handles normal workloads without extra noise. Integrated Intel HD Graphics 620 drives the display without a discrete GPU adding thermal load. Power draw stays within the original chassis limits, so the factory power adapter remains adequate.

Bundled hardware changes

The board includes two SODIMM slots supporting up to 32 GB of DDR4-2133 memory and an M.2 2280 slot that accepts both SATA and PCIe NVMe SSDs. HDMI 1.4 provides 4K at 30 Hz, while USB-C with optional Thunderbolt 3 enables 4K at 60 Hz. Buyers who need Thunderbolt 3 certification or more than two memory channels should look elsewhere.

Questions about this item

How do I install the LA-F322P motherboard into a Latitude 7490, and which step is most often missed?

Remove the battery first, then disconnect the display cable and all ribbon connectors before unscrewing the board; the step most often missed is forgetting to transfer the heat-sink thermal pads onto the replacement board.

What maintenance or replacement will the i3-7130U board need later?

The CMOS coin cell will eventually need replacing, and the thermal paste under the heat-sink should be refreshed every few years to keep the 15 W processor cool.

What limit appears first when the i3-7130U runs sustained loads?

The 15 W TDP ceiling is reached first, causing the chip to throttle its 2.7 GHz base frequency once the cooling solution saturates.
