Genuine Dell Latitude 3390 2-in-1 Motherboard
This genuine Dell OEM motherboard carries the integrated Intel Core i5-8250U processor, making it a direct replacement for the Latitude 3390 2-in-1 convertible laptop. It restores full system functionality for professional and educational users who need reliable hardware compatibility. The board is not suited for buyers who want a standalone desktop component or a different form factor.
Build Quality and Connector Implications
The green PCB is manufactured to Dell specifications for exact fit inside the Latitude 3390 2-in-1 chassis, aligning with the original mounting points and flex-cable routing. It supports high-efficiency DDR4 memory and M.2 SSD storage, so existing modules can be reused without adaptation. Technicians who lack the proprietary service manual or specialised tools for the convertible hinge assembly may find installation challenging.
Thermals, Noise and Power Draw
The integrated Intel UHD Graphics 620 handles everyday visual workloads without a discrete GPU, keeping the thermal envelope narrow and fan activity low during typical office tasks. The 1.6GHz base and 3.4GHz Turbo processor balances performance with modest power draw, supporting stable multitasking in the thin convertible design. Heavy sustained loads will raise temperatures, but the original cooling solution is calibrated for this board.
