Fix Touchpad Glitches with a Genuine Asus FFC Cable

What Is the Asus Touchpad FFC Cable?

The Asus touchpad FFC cable is a thin, flat-flex ribbon that links your laptop’s touchpad module to the motherboard. It’s responsible for transmitting every gesture, tap, and cursor movement with precision. If your touchpad becomes unresponsive, glitchy, or behaves erratically, this internal cable is often the root cause—especially after hinge movement, impact, or repair work.

1. Restores full touchpad responsiveness.
2. Eliminates cursor jumps and ghost movements.
3. Enables working gestures like scrolling and tap-to-click.
