7. Troubleshooting
- Pen not connecting: Ensure the pen is charged. Check your device's Bluetooth settings to confirm the pen is paired. If already paired, try unpairing and re-pairing.
- Buttons not responding: Ensure the pen is fully charged and properly connected via Bluetooth. Some users have reported that re-plugging the pen into the Surface device or hovering it over the screen can 'wake' the buttons.
- Inconsistent eraser function: Verify the pen is fully charged and connected. If the issue persists, it may indicate a specific software interaction or a need for a nib replacement.
- Nib leaving marks on screen protector: The graphite nib is designed to mimic a pencil. On matte screen protectors, it may leave pencil-like marks. This is a characteristic of the nib material and not a defect.
