Anyone know how to deal with a crazy mouse on a dell laptop?

I had the same problem for awhile, but I dont remember how/what fixed it. All I can do is say that it happened to me too, and it’s fixable. Have you contacted dell about it?

I would make sure that there isn’t any interference on the trackpad by cleaning well. Sometimes dirt or other things can give false input, especially in union with your finger. Make sure to clean all around the edges very good.

I use a homemade mix of 50% of isopropyl alcohol and distilled water in a spray bottle, which is exactly what’s in expensive display cleaners. A great solution for all computer cleaning needs.

It could also just be a dying trackpad, you never know. If that doesn’t help, the simplest solution would be to get an external mouse, either wireless or USB.

Also, if the cursor still goes crazy when using a mouse, see if there is a preference to turn off the trackpad when a mouse is plugged in.

I havent contacted dell. I went on their website and it wasnt very helpful, but I may just try it. I will also try what you all described in terms of cleaning, etc. Thanks!
