Wireless mouse scrolling up when I scroll down and vice versa.

[Schubhrojit]

I am using HP Z3700 Wireless Optical Mouse with my laptop for a few months now. For the past couple weeks the mouse wheel started misbehaving - like when I scroll down, the screen/page scrolls up for a second or two, and then scrolls down again. It does not happen always, but maybe for like 20 scrolls, 2 of them works this way. I tried cleaning the dust, changed the battery, worked with the mouse settings, reinstalled drivers. Nothing is helping. I am not using smooth scrolling, I repeat. NOT USING SMOOTH SCROLLING. It is just normal scrolling. I scroll up, the page scrolls down. I scroll down, the page scrolls up. For 2 seconds. And then goes back to normal scrolling (page scrolls the direction I scroll the mouse). Again, I have checked the mouse settings for scrolling direction as well.

hi

possible that it is an irreparable hardware problem
try the mouse with another computer, if the behavior is the same, then it will not come from a settings of your computer, most certainly
if possible try another mouse, on your computer, it works, then your mouse is certainly defective
