For HP 430/440/450 G6 Zhan66 14 15Pro G2 Main Board L44888-601/001 100% Tested

Description

What it is

• The “main board” refers to the laptop motherboard (also called system board) for certain HP notebook models: HP 430 G6, 440 G6, 450 G6 and HP Zhan66 (14/15 Pro G2) (or similar naming) — these are business-class / education notebooks from HP.

• The part number given is L44888-601/001 (sometimes seen as “L44888-601” or “L44888-001” etc). This is HP’s internal HP/Spare part number for that specific board revision. (Though online listings show similar numbers, e.g., L44888-601/001 for “430/440/450 G6 Zhan66 14/15Pro G2 Main Board”.) Alibaba+2Mercado Livre+2

• The “100% tested” claim means the seller indicates they have verified the board’s functionality (POST, basic I/O, etc) before shipping.

Key identifiers & decoding

• HP Notebook models:

  • “430/440/450 G6” means HP ProBook or HP Notebook models 430 G6, 440 G6, 450 G6.

  • “Zhan66 14/15Pro G2” – In some markets (especially China/Asia) HP uses the “Zhan” branding (for education/business) so Zhan66 14/15 Pro G2 is a variant of 14-inch/15-inch version. The board apparently is common to multiple model sub-variants.

• Part number L44888-601/001:

  • The “L44888” is the base HP board number.

  • The suffix “-601” or “-001” indicate board version or region/spare variation. It’s critical that your board version matches or is fully compatible with your notebook’s chassis, layout, cooling, connector positions and BIOS.

• “100% Tested”: Seller assurance (not HP official). Good sign for buying used/refurbished boards.

• Main Board: This includes CPU socket (or in many modern laptops, CPU may be soldered), onboard chipset, RAM slots, storage connectors, I/O ports, display/video subsystem, etc.

Features & what to look for

While I do not have the full HP service manual (unless requested) for that exact board variant, here are typical features for a board of this series & what you should verify:

• CPU/Processor compatibility: If the board is designed for certain Intel processors (e.g., 8th Gen Intel Core U-series) used in G6 models, ensure your original CPU (if removable) or your notebook model matches.

• Memory (RAM) support: Does the board have 1 or 2 DIMM slots (DDR4). Ensure your RAM type & capacity is supported.

• Storage connectors: Check for M.2 SSD slot, SATA ports (if applicable), and location.

• Graphics / video output: Built‐in integrated GPU via CPU; check display connector (LVDS/eDP) matches your screen. Also verify HDMI/USB-C (if available) ports on I/O bracket.

• I/O ports / connectors: USB ports, audio jack, Ethernet (if present), WiFi/Bluetooth module slot (M.2 or mini-PCIe), etc. Must align with your chassis cut‐outs.

• Cooling assembly & heatsink mount locations: The board must match the thermal design (screw holes, heat pipe alignment) of your laptop chassis.

• BIOS version / firmware: Some boards require correct BIOS region or processor support; mismatched BIOS may cause boot issues.

• Revision version: The “-601” or “-001” suffix may denote board revision differences (layout tweaks, connector changes). It’s safest if the spare part number exactly matches or is declared “compatible with” your model.

• Condition & testing: As the listing says “100% tested”, you should ask which functions were tested (boot, display, I/O, USB, WiFi, etc). Also check returns warranty.

Compatibility / Fitment Considerations

• Model exact match: Ensure your laptop model (e.g., HP ProBook 440 G6) is among the supported list for that board. Even slight sub‐models (e.g., roof‐version, region) may have board differences.

• Chassis & screen size: The board for 14″ vs 15″ may differ in connectors or layout. Confirm if the board listing supports both 14″ and 15″ “Zhan66 14/15Pro G2”.

• Processor and configuration: If your original board had a certain CPU or GPU configuration (e.g., MX130 discrete GPU or not), you want to ensure compatibility. Some boards integrate GPU or have soldered processors.

• Region / keyboard layout / I/O ports: Some boards have regional variants (keyboard connectors, I/O port arrangement). If your chassis expects certain USB ports on right side vs left, board must match.

• Cooling/heatsink alignment: The heatsink mounting must match screw holes on board. If board revision changed, your original heatsink may not line up.

• Connector orientation: Display cable orientation, WiFi module slot, battery connector – verify exact match.

• BIOS setting / security: Some HP laptops have BIOS disabled if board serial doesn’t match original – may need BIOS update or HP service.

• Used part risk: Since this is likely a used/refurbished board (common for older laptops), ensure the seller gives at least a return window and describes condition (any missing components, damaged traces). Buyer may need to transfer heatsink/thermal paste from old board.

Benefits & Why Replace the Board

• Replacement of a failed motherboard (e.g., due to power surge, short circuit, malfunctioning ports, dead system) restores full functionality without buying a new laptop.

• Retains your original components (RAM, SSD, screen, keyboard, hinge, etc) if board is fully compatible.

• Cost-effective compared to buying full laptop when your issue is limited to the board.

• For refurbishing or repair business, these boards often available in market as “tested” parts.

Risks & What to Watch Out For

• Compatibility uncertainty: If any board revision differs, you may face mismatch issues (connectors, I/O cut‐outs, BIOS).

• No warranty / limited testing: “100% tested” is seller promise, but still a used part—long‐term reliability may be unknown.

• Thermal/heatsink issues: Transferring cooling solution must be done carefully (heatsink, heatpipe, thermal paste) to avoid overheating.

• Serial/asset tracking: If laptop is managed by enterprise, replacement board may trigger asset/BIOS mismatches.

• Firmware/BIOS update needed: Board may come with older BIOS not updated for your CPU or newer peripheral – can cause stability issues.

• Hidden damage: Board may have cosmetic damage, missing connectors, solder joints that will fail later.

• Shipping/import cost/time: For purchase internationally (e.g., shipping to Rwanda/Kigali) check import duties, shipping time, return logistics.

Practical Steps for Installation

1. Acquire the correct board: Part number L44888-601/001 (or variant) and ensure listing states compatibility with your exact laptop model.

2. Prepare your workspace: Anti‐static mat, proper screwdrivers, small trays for screws.

3. Remove battery, disconnect power, unplug all external devices.

4. Remove bottom cover of laptop following HP disassembly guide for your model (G6, etc).

5. Remove cooling assembly (heatsink, fan) from old board and transfer to new board, cleaning thermal paste and reapplying fresh paste.

6. Carefully remove connectors (display cable, keyboard/backlight cable, touchpad, WiFi module, speakers, etc) from old board and replicate on new board.

7. Place new board into chassis, screw mounting screws in correct order, connect all cables.

8. Reinstall cooling assembly, attach fan connector, battery, bottom cover.

9. Power on and test: BIOS access, memory recognized, SSD recognized, display works, USB ports functional, WiFi works, etc.

10. Update BIOS if necessary (from HP support site) to latest version.

11. Monitor temperatures under load to ensure cooling works properly.

Summary

In summary: The “HP 430/440/450 G6 / Zhan66 14/15Pro G2 Main Board L44888-601/001 100% Tested” is a laptop motherboard replacement part for specific HP laptop models. It’s a crucial component that carries the CPU chipset, memory slots, storage connectors, I/O ports, etc. If your laptop’s motherboard has failed (and other components are still good), replacing it with this board (or one fully compatible) can restore your system’s functionality. However, ensure full compatibility (model, board revision, cooling, firmware) and buy from reputable seller with testing verification. Because it is a used/refurbished board, do expect some risk and check return policy.
