Question about Dell Inspiron 8200 Latitude C840 Laptop Keyboard03J247 CD-ROM Drive
I have a Dell Latitude C840 laptop. My mouse will start movving on its own and go to the lower left hand corner or to the upper right hand corner and not be able to be moved for a while. The mouse then becomes available to be controlled for a while and then it will do it again. I will do it with just the touchpad or even when a mouse is attached. Any suggestions?
Its actually the blue thing that u can also controll with so just take th elue cap of and wiggle it around n it should stop

My mouse got worse and worse until it did it every time the computer was on. I took the key board off and unplugged the center mouse (blue/purple pencil eraser thing)from the connector. I had to un-clip one side of the connector to pull the mouse ribbon out. Be careful that you do not break the connector latches. Once I put it all back together and turned it on the mouse problem has not returned. Problem solved. To take the keyboard out you have to remove the screws on the bottom of the laptop. I am not sure of the exact screws. None of the panels on the back need to come off. It took me about 10 minutes to do everything. Good luck.

I have not torn the Dell laptop apart yet, but I think I know what causes the problem. At least in my case, the problem is a short in the wiring or on the board. I believe it is caused by my right hand resting down on the area over top the DVD drive as I use the touchpad to maneuver the mouse. As I found in one solution web site, just press briefly beside the mouse pad (in my case about 1.5 inches east) and it will eliminate the problem. It seems to be a design flaw and people have had good response from disconnecting the track mouse cable (Go to Dell for instructions). If it becomes to distracting or unusable, I will tear off the case and investigate further as to the actual physical cause.

My dell laptop does the same thing. I found that dell wouldn't replace my touch pad so what i typically have to do is push on the laptop around the touch pad until it starts working again. Sometimes I restart and that fixes the problem. I think there is something that is shorting out in the case and if you push around the touch pad and put pressure in and around that area it usually starts working again. This does not happen very often if it happens very often call dell support and get them to replace it esp if you can get them on the phone when the problem occurs.
