Chosen Solution
Hello. I have a strange problem with my Macbook Pro A1286 Core i5 2.4 Ghz and Trackpad. The trackpad “click function” is good, but there is no way to resolve the problem of no scrolling. I have try also to change the trackpad with a new one and to change also the entire trackpad cable but I haven’t resolve my problem. Try also to Reset PRAM and SMC but without any result. Try also to Remove the battery … nothing … So I have start to check the Macbook Mainboard for try to find something that can be the cause to the problem. All it seem to be ok, but there is a small point that I would understand that can be the cause of all. I attach some photos…you can find a “small” component that it seem to have a small break … So the question is:- “can be this component the cause of all ?”. Or do you have any idea about the solution of the problem ? Thanks in advance for your help guys.

You said click works, but can you also move the mouse pointer around with one finger? If so, test to see if other multitouch gestures work. If any of them work you can rule out the possibility of a hardware problem. There could also be an issue with Mac OS X settings that is causing multitouch not to work properly. If you have OS X install media (or the ability to create a bootable USB drive), boot the computer off of that and see if the gestures work in the OS X installer.
