I've been using my ASUS X751 for several years and the touchpad it has recently become squirrelly. It's as if the spot where I want the pointer to be (which can be anywhere on the screen) has a virtual magnet, and the pointer itself has a magnet of the same polarity. The pointer is happy to go anywhere except the very spot where I want it to go, no matter how carefully I tweak it. It'll go slow, slow, slow, until I am within a dozen pixels, then FAST to the other side, then slow slow. I know this typically occurs if there is dust or detritus on the touchpad, and the sensor gets confused, but I wipe it down every time to be sure there's nothing interfering. I am pretty certain that this is not a driver issue (and I've checked that I've got the latest); it is surely a hardware wear & tear issue. It does not occur with mouses or graphics tablet. Is there anything I can do to obviate this? I'm not sure the touchpad will come off from the outside (like keys can) and I doubt I could get at it from the back, since it'll be buried under other components.
