It's a common question in the forums.
Disable the touchpad and if you can't, look up TOUCHFREEZE.
I bought a locally assembled, Zyrex computer about a year ago. I bought it second-hand from a store, and it works ok except for one very annoying habit that has started. As I touch type on it, the screen cursor will suddenly leap to another line, another page, or elsewhere.
I have analyzed what could be wrong but can?t figure a cause. First, I thought it might be interference from the touch pad, which I never use. I tried getting help to disable the touch pad but couldn?t make it happen. Nevertheless, as a test, I?ve watched my hands as I type to see if my fingers are hitting the touch pad but I don?t think they are.
The same thing with my fingers hitting multiple keys. Sometimes that happens on a crowded keyboard but not all the time. Yet, sometimes my laptop can?t type for five or ten seconds without leaping to another part of the document.
Has anyone else had this problem before with a laptop? Maybe there is a short circuit between the electronics and the body of the machine? Thanks for any ideas or help.
