Replacement Touchpad Button Board

The Fans 15-G100 mouse button board is a new replacement part for specific HP laptop models. It restores left and right click function when the original touchpad button assembly fails or suffers physical damage. The board matches part number 749651-001 and fits the listed 15-G series chassis.

For HP 15-G Series Owners Needing Click Repair

This part suits owners of HP 15-G100, 15-G109WM, 15-G163NR, 15-G170NR, 15-G173WM, 15-G227WM or 15-G274NR laptops who need to replace a faulty button board. It is not for users with different HP series, other brands, or models outside the listed compatibility codes. Buyers needing a full touchpad module with pointing surface should look elsewhere.

Verify Exact Model Code Before Ordering

The single specification that decides fit is the exact laptop model number and the 749651-001 part code. HP uses several similar boards across the 15-G family, so visual comparison with the original LS-A992P ZSO51 board is essential before purchase.

Questions about this item

How is the 15-G100 button board installed and which step causes problems?

Remove the bottom case screws, disconnect the battery, then unplug the old board's ribbon cable; the step people get wrong is not locking the ZIF connector fully, which leaves the buttons dead.

What maintenance or replacement will the 15-G100 button board need later?

The board has a 6 Months feature period; after that the tactile switches can wear out, so plan to replace the whole board if clicks become inconsistent.

What limit appears first on the 15-G100 button board during sustained use?

The plastic switch stems fatigue first under heavy daily clicking, causing double-clicks or missed presses before the ribbon cable or solder joints fail.
