My friend is bringing over his Compaq Presario tonight because the cursor is jumping all over the screen. To me, it sounds like the touchpad has gone up. I do not have much experience with laptops, but here is what I think: I would like to disable the touchpad and attach a USB or PS2 mouse (it has both types of ports). Can I disable the touchpad in the bios or somewhere else? What do you all think about the situation?
