HP laptop touchpad button board

This replacement touchpad mouse button board fits HP 15 series laptops including the 15-R021NG, 15-R026NA, 15-R029WM, 15-R030NA, 15-R030NR, 15-R030WM and 15-R033CA models. It restores left and right click functionality when the original board fails or is damaged. The part matches component codes 749651-001, LS-A992P and ZSO51 for direct compatibility.

New condition with precise fit

Supplied new, the board aligns with the existing mounting points and ribbon connector on the listed HP 15 models. No soldering or modification is required during installation. The part is a direct physical match for the original component, so the touchpad assembly sits flush and the click action feels consistent with the factory fit.

Passive component with no power draw

The board contains only the button switches and connector traces, drawing negligible power from the laptop's touchpad controller. It adds no audible noise, generates no heat and requires no driver or firmware updates. Operation is purely mechanical, so reliability depends on the switch lifespan rather than any active circuitry. Buyers needing a full touchpad sensor assembly or a different HP series will not be served by this part.
