Hello everyone. I've been experiencing something weird the past couple of days. My mouse cursor randomly jumps to the upper left hand part of the screen. Doesn't matter if I'm using the trackpad or my mouse. Not sure at all what causes it, but I haven't made any major changes to my machine.
I have seen this a lot where the trackpad registers movement when the person is typing.
To test this, try disabling the trackpad entirely for a day and then use the USB mouse only and the computer as normal. Observe if the mouse-jump stops. If it does, it gives us an idea of the cause and possible solutions.
My first thought is Bluetooth is on, regardless of whether the mouse is connected or not. Try turning off Bluetooth and see if it happens with just the trackpad. If not, then there is an interfering signal (phone, microwave, remote, rc car, drone... etc) interfering. Upgrade your wifi/bluetooth adapter to resolve.
I finally got a chance to work on this and I tried a USB mouse, I also tried disabling bluetooth, and I upgraded my wifi/bluetooth adapter on my motherboard. I also replaced the SSD on this machine and did a clean install, plus I also physically disconnected the touchpad and the problem still persists. I think at this point it's a hardware issue so I'm not sure what to do
Though you disconnected it, did you disable it in the os (the TouchPad). It sounds like the TouchPad or the mouse has issues.
I'm also curious what kind of surface the mouse is on. Glass, some reflective surfaces and carpet can cause this erratic behavior depending on the age of the mouse and optics. Newer optics are a bit more forgiving but can produce the same effect depending on the material it is used on.
On the mouse itself, when was the last time you cleaned the optics? While disconnected, use a Qtip and rubbing alcohol or windex, until the optics window doesn't discolor the qtip.
If these suggestions don't resolve it, try another mouse.
