DELL Latitude 7280 7380 Motherboard i5-7300U 2.6GHz GDK56

Genuine Dell Latitude 7280 7380 Motherboard

This genuine Dell OEM system board carries the part number GDK56 and includes an on-board Intel Core i5-7300U processor running at 2.6GHz. It is designed as a direct replacement for the Latitude 7280 and Latitude 7380 laptops. Buyers who need a board for a different Dell series or a socketed CPU upgrade cannot use this part.

Sustained Load Behaviour

The integrated i5-7300U operates within a low-power envelope suited to ultrabook thermals. Under continuous workloads the processor will throttle to stay within its thermal limits, so performance settles below the 2.6GHz base clock. The cooling solution belongs to the laptop chassis, not the board, so sustained output depends on the original heatsink and fan assembly.

Installation Notes

Replacing the system board requires a near-complete teardown of the Latitude 7280 or 7380 chassis. Common issues include damaged display or keyboard flex cables during disassembly, forgotten screw locations, and BIOS mismatch if the replacement board ships on an older firmware revision. Technicians should label every cable and verify the service tag in BIOS after the swap.
