I have an Aspire 5520-5912 laptop. I am having trouble with erratic cursor movement. For no apparent reason, the cursor will move from one point to another, often causing trouble with a document I am typing. It does the same thing when searching on a browser (it doesn't matter which one). Oftentimes, for no apparent reason, it will switch applications while I am typing. I thought it might be the touchpad, but I can't find a pattern there either. Any help would be appreciated. Thanks.

Re: Erratic Cursor Behavior
Are you sure your not touching the pad as you type , a common error, cover the pad with card board or plastic and see. otherwise you may have a bad touchpad and it needs replaced or re-seated on the cable.

What platform? Memory (needed for this sort of task)? WiFi gateway? Model?
Importantly, have you attached any Apple devices to your system recently?
If the connection is Bluetooth (to TV), well, there's not much help for it. You need a lot of CPU and Memory for smooth flow and device functionality.
Have you by chance downloaded a new Service Pack for Windows? Try booting into safe mode and doing a System Restore (if possible), if not try taking out your RAM Module(s) and re-seating them (it). If more than one try re-seating each one separately. One bad module could cause erratic behavior.
Mouse is not clean
Users who have an optical mechanical mouse (most common mouse for desktop computers) are likely experiencing erratic behavior because the mouse is not clean or is dirty. Optical portion of mouse is blocked
Users who have an optical mouse are likely experiencing erratic behavior because a portion of the optical eye is blocked. Most commonly this is caused by a hair.
Moisture or other material on finger
Users who are using a touchpad may experience erratic behavior because of moisture or other material on the finger such as lotion.
Mouse has been cleaned and still has problems
If you've cleaned the mouse and continue to encounter issues and this mouse has worked in the past fine unfortunately your mouse is likely defective. One additional test that can be done to help determine if this is the case or not is to connect the mouse to another computer. Otherwise we suggest replacing the mouse.
Well, there are a lot of factors that could be involved with your cursor acting up. For starters, could you answer if it is a trackball, optical, or laser mouse? What kind of surface are you using it on? And did it come with a driver CD that you have installed?
Generally, your cursor will move erratically when the sensor that detects movement of the mouse is fed mis-information. If it's a trackball, this can happen when foreign material is caught along the inside wheel sensors besides the trackball. On an optical mouse, it can be similar foreign material interfering with the digital camera's ability to take pictures of your mouse surface. Similar for a laser, but they are much more precise.
Could you provide us with more information? Thanks!
