Dell Latitude 7280 — motherboard, i5-7300U (GDK56)
A genuine Dell Latitude 7280 system board, part number GDK56, with the Intel Core i5-7300U soldered on board, USB-C and TPM. Tested and graded in Melbourne, covered by a 12-month Reboot IT warranty with free standard AU shipping.
Key Benefits
-
Genuine Dell part GDK56: The factory planar reference for this configuration, so mounting points, port alignment and cable connectors match the 7280 chassis exactly.
-
Intel Core i5-7300U on board: Dual-core, four-thread, 2.60GHz with a 3MB cache — the processor is soldered to the board, so this part determines the CPU the machine will run.
-
Intel HD Graphics 620: Integrated graphics with DisplayPort over USB Type-C, supporting external displays through the Type-C port.
-
USB-C variant: This board carries the USB Type-C configuration with DisplayPort output — confirm your chassis matches before ordering.
-
TPM fitted: Trusted Platform Module present on the board, supporting BitLocker and corporate compliance requirements.
-
Tested before dispatch: Powered up and verified — processor, memory training, ports and TPM state — before grading and dispatch.
Fitment & Installation
This board suits the Dell Latitude 7280 in the USB-C, TPM-equipped configuration. Because the i5-7300U is soldered in place, the board and processor are a single unit: a replacement must match the CPU you intend the machine to run, and this one is the i5-7300U. Verify the part number on your existing board reads GDK56 before ordering.
A motherboard replacement is the usual answer to liquid damage, a failed port bank, or a board that no longer posts, where the rest of the machine — screen, chassis, keyboard, battery — is sound. For an IT department holding several 7280s, keeping a known-good board on the shelf turns a dead unit back into a working one in an afternoon.
Note that the i5-7300U is a 7th Generation processor and is not supported for Windows 11. A machine rebuilt on this board should run Windows 10, which remains appropriate for offline, kiosk, point-of-sale and controlled-fleet roles.

How We Test It
Each board is fitted to a donor Latitude 7280 chassis and powered up before grading. We confirm the board posts, trains memory correctly and reaches the BIOS; verify the processor is recognised and clocks correctly; exercise the USB Type-C port for data, video and power delivery; check the USB-A ports, audio and video output; confirm the TPM is present and reports a healthy state; and verify the Wi-Fi antenna connections. The BIOS is then reset to factory defaults with any prior owner passwords cleared.
Supplied as the bare board only. Memory, storage, heatsink, fan, battery, wireless card and all cables are not included — reuse the parts from your existing machine. Installation is not included and should be carried out by an experienced technician.
Frequently Asked Questions
Which laptop does this board fit?
The Dell Latitude 7280 in the USB-C, TPM configuration. Confirm the part number on your existing board reads GDK56 or 0GDK56 before ordering.
Can I change the processor on this board?
No. The Intel Core i5-7300U is soldered directly to the board and cannot be swapped. The board and CPU are a single assembly.
Will a machine built on this board run Windows 11?
No. The i5-7300U is a 7th Generation processor and is not on the supported list for Windows 11. Windows 10 is the appropriate operating system.
Does the board include memory?
Memory is not part of this listing. Fit the memory from your existing machine or source it separately.
Is the TPM functional?
Yes. The TPM is present on the board and its state is verified during testing, so BitLocker and corporate compliance features are supported.
What is tested before dispatch?
The board is powered up and checked for processor operation, memory training, port function, video output and TPM state before grading.
