Replacement motherboard for Latitude D620

This motherboard carries part number XD299 and fits the Dell Latitude D620 chassis. It provides two DDR2 memory slots and on-board audio for a direct board-level repair. Technicians and DIY owners use it to restore a working system without replacing the entire laptop.

Sustained operation with DDR2 memory

The board runs two DDR2 modules in dual-channel fashion, keeping bandwidth steady during long sessions such as office suites or video playback. Thermal design spreads heat across the PCB rather than concentrating it under burst loads. No throttling behaviour is documented beyond the original Dell engineering.

Thermals and power in daily use

Heat from the chipset and voltage regulators is dissipated through the laptop’s existing fan and heatsink assembly. Acoustic output matches the original cooling profile because the board reuses the same mounting points and thermal pads. Power draw stays within the factory spec for the Latitude D620 platform.

Questions about this item

How much heat and fan noise does the XD299 motherboard produce when the Latitude D620 runs all day?

The board uses DDR2 memory and on-board audio, so power draw and heat stay within the original laptop thermal design.

What other parts must I already have to install the XD299 motherboard in a Latitude D620?

You need a compatible Intel processor, DDR2 memory modules, the laptop chassis, cooling assembly and power connector.

Will the XD299 motherboard work with the existing DDR2 memory and drives from my older Latitude D620?

Yes, it supports the same DDR2 memory slots and on-board audio, so your current memory and internal drives remain compatible.
