Fix Touchpad and Touchscreen Issues with a New Asus Controller Board

Restore Full Touch Input Functionality and Gesture Control

If your laptop’s touchpad or touchscreen is unresponsive, jumpy, or missing gestures, the internal Asus touch controller board may be the culprit. This small but essential component transmits all touch signals—taps, swipes, multi-touch, and cursor movement—to your motherboard. When it fails, you’ll notice erratic cursor movement, touch not registering, or palm rejection glitches.
Typical signs of failure include frozen touch response, cursor drifts, broken flex cable, or intermittent gesture recognition. These issues often occur after a drop, water damage, or flex cable wear from repeated lid use. Instead of replacing the entire touchpad or motherboard, installing an OEM Asus touch controller board is a fast and cost-effective solution.
