Trackpad Scrolling Jumpy Fix
The ASUS Zenbook 14 OLED UM3402 uses a precision touchpad with smooth glass surface. Jumpy or erratic two-finger scrolling — where the page jumps up or down randomly instead of scrolling smoothly — is usually caused by palm rejection misfiring, an outdated touchpad driver, or Windows scroll direction sensitivity settings.
Fix 1: Adjust Scrolling Sensitivity
Go to Settings > Bluetooth and devices > Touchpad > Scroll and zoom. Reduce the scroll speed to a lower value. Also ensure Drag two fingers to scroll is enabled. Overly high scroll sensitivity on the Zenbook 14 OLED glass touchpad causes the slightest finger movement to register as a large scroll jump.
Fix 2: Update ASUS Touchpad Driver
Visit ASUS Support, search for the Zenbook 14 OLED UM3402, and download the latest Touchpad driver (ELAN or Synaptics). The ASUS-specific touchpad driver includes palm rejection and gesture calibration tuned for the Zenbook 14 OLED hardware. Install and restart before retesting scrolling behavior.
Fix 3: Clean the Touchpad Surface
Wipe the Zenbook 14 OLED touchpad surface with a dry microfiber cloth. Oils, moisture, or debris on the glass touchpad surface cause finger tracking inconsistencies that manifest as jumpy scrolling. Even very light contamination can interfere with the capacitive sensor layer under the glass. Keep the surface clean and dry for accurate tracking.
- Also ensure your fingertips are dry — sweaty or moisturizer-coated fingertips cause erratic capacitive sensor readings
- Avoid resting the palm on the touchpad while scrolling with two fingers — palm rejection may incorrectly interpret the gesture
Fix 4: Disable Pinch to Zoom
In Settings > Touchpad > Scroll and zoom, disable Pinch to zoom. On the Zenbook 14 OLED the touchpad occasionally misinterprets a two-finger scroll as a pinch zoom gesture, causing the apparent scroll jump. Disabling pinch to zoom prevents this misclassification without affecting regular two-finger scrolling.

Why does the ASUS Zenbook 14 OLED UM3402 trackpad scroll jump?
Jumpy scrolling on the Zenbook 14 OLED touchpad is usually caused by high scroll sensitivity, pinch-to-zoom gestures being misclassified as scrolls, or an outdated ASUS touchpad driver. Reduce scroll speed in Settings > Touchpad > Scroll and zoom, disable pinch to zoom, and install the latest touchpad driver from ASUS Support.
What touchpad does the ASUS Zenbook 14 OLED UM3402 have?
The ASUS Zenbook 14 OLED UM3402 includes a precision glass touchpad with support for Windows 11 precision gestures. The touchpad uses a capacitive sensor layer under a hardened glass surface for smooth finger tracking. It supports all standard Windows 11 multi-finger gestures including three-finger swipe and four-finger tap.
Does the ASUS Zenbook 14 OLED UM3402 have an NumberPad on the touchpad?
Yes. The Zenbook 14 OLED UM3402 features ASUS NumberPad 2.0 — a virtual numeric keypad embedded in the touchpad surface. Press and hold the NumberPad icon in the top-right corner of the touchpad to toggle the LED number overlay. Disabling NumberPad when not needed prevents accidental activation during scrolling gestures.
Can the ASUS NumberPad cause scrolling issues on the Zenbook 14 OLED?
Yes. If NumberPad mode is accidentally activated, the touchpad enters a special input mode that can affect normal scrolling and gesture behavior. If scrolling suddenly becomes erratic, check the top-right corner of the touchpad for the NumberPad indicator light. Press and hold that corner to toggle NumberPad off and restore normal touchpad operation.
