Alienware M15 R3 & M17 R3 Junction Board

This genuine Dell OEM junction circuit board carries part number HH20M and is built for Alienware M15 R3 and M17 R3 laptops. It manages power distribution and signal routing between key internal components. The blue PCB is precision-engineered for stable electrical performance under heavy workloads. It serves as a direct replacement for a failed or damaged power interface board.

Verify exact laptop model and board revision

Confirm that your unit is an Alienware M15 R3 or M17 R3 before ordering, as the HH20M board is not interchangeable with other Alienware generations or Dell series. Check the existing board for visible damage, burnt traces or connector wear to ensure the fault lies with this component. Disassembly requires motherboard-level access and appropriate ESD precautions. Buyers without board-level repair experience should seek professional installation.

No extra cables, firmware

The package contains only the junction circuit board itself; no ribbon cables, screws, thermal pads or software are bundled. Re-use all original fasteners and flex cables from the removed board during installation. No driver updates or BIOS changes are required because the component is purely electrical. The absence of additional parts keeps the repair focused and cost-effective.

Questions about this item

Does the HH20M junction board arrive alone or with mounting hardware and cables?

The listing shows only the HH20M junction circuit board itself; screws, thermal pads and ribbon cables are not included and must be sourced separately if the originals are damaged.

My laptop is an Alienware M15 R3 — will the HH20M board fit, or do I need a different revision for the M17 R3?

Part HH20M is specified for both the Alienware M15 R3 and M17 R3, so a single board covers either chassis without a separate revision.

Once installed, what does the HH20M board actually do for system stability under heavy gaming loads?

It routes and distributes power across the motherboard’s critical rails, maintaining clean voltage delivery so the CPU and GPU can sustain boost clocks without throttling from voltage droop.
