Dell Inspiron 5566 replacement board

This LA-D871P motherboard (part DMD9K) is a direct replacement for the Dell Inspiron 15 5566. It arrives with a soldered Intel Core i3-7100U processor running at 2.4GHz and integrated Intel HD Graphics 620. The board targets owners repairing a failed system board or liquid damage.

Sustained operation with integrated graphics

The dual-core, four-thread CPU handles everyday workloads such as web browsing, document editing and video playback without thermal throttling under normal use. Integrated Intel HD Graphics 620 shares system memory, so performance scales with the DDR4 modules installed. The board is designed for typical productivity duty cycles rather than continuous heavy compute.

Genuine Dell layout with standard connectivity

As an original Dell component, the board matches the chassis mounting points and connector positions exactly. It provides two SODIMM slots supporting up to 16GB of DDR4 memory and a SATA interface for a 2.5" drive. Ports include Gigabit Ethernet, USB 3.0, USB 2.0, HDMI and an SD card reader. Buyers needing discrete graphics or additional M.2 storage should verify their chassis supports those features separately.

Questions about this item

How much heat and power does the soldered Core i3-7100U at 2.4GHz produce during all-day use?

The integrated Intel Core i3-7100U is a 15-watt dual-core chip, so sustained loads generate modest heat that the original Inspiron 15 5566 cooling assembly is designed to handle without extra power draw.

Which existing components must I already own to install this DMD9K motherboard?

You will need two DDR4 SODIMM sticks up to 8GB each, a 2.5-inch SATA drive, the Inspiron 15 5566 chassis, display assembly, keyboard, battery and original heatsink-fan module.

Will my current DDR4 memory and 2.5-inch SATA drive work with this LA-D871P board?

Yes, the board accepts two DDR4 SODIMM modules up to 16GB total and provides a SATA III connector for any 2.5-inch SATA HDD or SSD you already use.
