How to maintain the touchpad of ASUS A55VM series as follows:
1. When using the touch pad, be sure to keep your hands clean and dry to avoid inaccurate cursor positioning.
2. If the surface is accidentally dirty, you can wet a corner of the dry cloth and gently wipe the surface of the touch panel. Do not use a coarse cloth to wipe the surface.
3. The touchpad is a sensitive electronic component. Do not use sharp objects (such as pens) to write on the surface of the touchpad, and do not use it with heavy pressure to avoid damage.
