WTAF is going on with my laptop and mouse!!!!!!!! (Win10)

Coonamble has had all this rain, and there is a terrible mouse plague. Dead and dying mouses everywhere, some with blue teeth.

Just updated windows 10 yesterday and the mouse acted like someone else was using it. I unplugged the RJ45 and still had the problem. Looking deeper, the CPU was maxed out at 100% so not much processing power going to the mouse. After waiting a while, it calmed down and started working ok but took a long time, an hour or so. I think the new update was still working on things in the background so you could do things in the foreground, didnt work.

I had a similar issue some years ago too. Every time I opened a combobox list it scrolled down to the last item. It took me some hours of investigation until I realized that I had a powered-on cordless mouse in my backbag :-)

I am not aware of anything on the mouse that can change the screen scrolling mode/state

Middle-click does this, so it could be a faulty middle mouse button (the scroll wheel on most mice).

Is your mouse old? Those same things happen to me when my mouse has too much wear. The sensors start to go crazy, and it starts suddenly.

I've seen this before as far back as Windows 2000. You have a device sending spurious interrupts to the system. The usual culprit is a battery powered mouse with weak batteries, but I've seen keyboards and other wireless devices do the same thing.

(Tongue firmly in cheek)It is St. Patrick's Fay. Check for leprechauns.(/Tongue firmly in cheek) It sounds familiar. My mouse is a wired Kensington mouse and I had similar problems a year back. It turned out to be a nearly invisible hair in the optical socket for the mouse. Once removed, everything returned to normal.

I have had similar behavior when I have accidentally left my travel mouse on in my backpack.

When anyone at the office complains about this type of symptoms, my first question is, "do you have any paperwork, magazines, or books that are getting onto your keyboard?" My second question is whether the scroll-lock light is on. I will often get an "Oh. That fixed it" comment. If they tell me "no", then I send out a replacement keyboard for them. With only rare exception, that fixes the problem. For those exceptions, I replace the mouse. There are many things that can be adversely affected by "stuck keys" on the keyboard, including mouse functions like scrolling. If you are someone that eats at your desk (I do that too) you could have crumbs, oils, coffee, cola, mold (yes, I have seen that one at someones desk before X| ), or something else that is affecting keys. Those keyboard cleaners that look like you are pressing silly putty onto your keyboard actually to an excellent job. I find they work better than canned air, brushes, or mini vacuums in most cases (although I like the combination of keyboard putty and canned air). Money makes the world go round ... but documentation moves the money.

When I accidently press/click the wheel in the middle between the left and right buttons, it gets into that mode. Then when I click the wheel again, it returns to normal mouse mode.
