    Was it clicking around or just the movement was jerky?

    Yes, It usually happens either under high load, when mouse interrupts are
    significantly delayed. Or sometimes it happen when applications poll
    battey status and on some boxes it takes pretty long time. And because
    it is usually the same chip that serves keyboard/mouse it again delays
    mouse interrupts.

    Btw, what kind of laptop/touchpad is that?
