Motherboard with Pentium 5405U

This Dell LA-G712P motherboard includes an Intel Pentium 5405U processor running at 2.3GHz. It is a genuine OEM replacement part built for Inspiron 15 3580 and Inspiron 17 3780 laptops. The board supports DDR4 memory and provides integrated Intel UHD Graphics 610 for display output.

Repair suitability

The part suits owners of the listed Inspiron 15 3580 or Inspiron 17 3780 models who need to replace a failed system board. It is not for users with different Dell models, other laptop brands, or desktop systems. Buyers who need a board without a soldered processor or who require a different CPU should look elsewhere.

Soldered Pentium 5405U processor

The Intel Pentium 5405U is permanently soldered to this motherboard, so the CPU cannot be upgraded or swapped separately. This fixed 2.3GHz dual-core configuration determines the performance ceiling for any repair. Verify that this specific processor meets the required workload before purchasing.
