A mouse is a vital component of your computer and allows you to control certain functions on the screen. When the mouse is not functioning correctly, it can be frustrating. There are a few different reasons why your mouse pointer may jump on the screen. You need to work through the possible causes and troubleshoot the problems to fix your mouse and get it working properly again.
1. Examine the batteries if you have a wireless mouse and the cursor begins to jump. A low battery may be the cause. Change the batteries and check the mouse again. If it is still experiencing the same problems, proceed to the next steps to resolve the issue.
2. Switch the wireless transmitter to a different USB port on another computer if possible. There could be problems with the port, causing the cursor to jump. This will resolve the problem if the issue is with the USB port. If the mouse is still jumping, move on to the next steps.
3. Click on the "Start" menu in the bottom left corner of the screen. Right-click on the "My Computer" menu and click on "Properties." Click on the "Hardware" menu and click on "Device Manager." Locate the mouse entry in the list. Right-click on it and select "Update Driver" from the menu. Allow a few moments for the operating system to locate and install an updated driver for your mouse.
4. Remove dust or debris from the mouse pad and mouse with a soft cloth. Dust or debris could prevent the mouse from operating smoothly and cause the cursor to jump. Add a small amount of isopropyl alcohol to the cloth before you begin. Wait for the alcohol to dry on the pad and mouse prior to using. 5. Go to the "Start" menu and click on "Control Panel." Double-click on the "Mouse" icon and click on "Mouse Pointer." Decrease the speed of the mouse pointer. This could be causing the cursor to jump. I hope you find it very helpful. Thank you.
That sounds a lot like someone has remote access to your computer. Try changing your Firewall settings or try to get a different IP address. Careful messing around with the IP though, it's easy to create a problem when doing that.
Does the cursor jump around when your hands are nowhere near the touchpad? The touchpads are heat and pressure sensitive. I personally have very warm (and sometimes sweaty) hands. I have this problem often when working on laptops. If I hover my hands over the pad, it causes the mouse to move. I've had to take a business card, put tape on one side of it, and use it as a flip-cover for the touchpad on most of my laptops. If the cursor moves around when you're nowhere near the laptop, then you may want to try disabling the pointing stick (if it has one). I've had several clients with laptops where the pointing stick mouse control go crazy and move and click on things.
In windows xp go into start menu, then into control panel then click on appearance and themes, then move your mouse over to mouse pointers click on it , uncheck "enhance pointer precision, and click apply, that will stop the mouse from acting crazy, this will work with dell mouse pointers and most.
Hi - I've been having the same problem and it is MAJORLY annoying to be typing along, and have the cursor reappear on another line!
I had a heck of a time finding the place to disable the touchpad, since we use a USB mouse with the laptop. Turns out, someone else helped me find a simple way - hold down the Fn key (next to the left side CNTRL key), and hit F7. That toggles the touchpad off/on easily!
Also suggested by someone else, some mice can cause erratice behavior with Acer laptops, so perhaps try another mouse?
So far, I've been typing this response AFTER disabling the touchpad, and the cursor has not jumped around at all.
