Please help! Track pad of unibody MB does not work!

[dess]

Hi there! The track pad of my bf's unibody MB stopped working! I have tried restart, removing the battery, resetting the SMC, plugging an external mouse but nothing seems to fix the problem. The keyboard works fine but that's not of much use. 😡

Any ideas what might fix this?

Thanks in advance.

If you take the battery out of the bottom, you will see some wires and circuit boards covered with a transparent piece of plastic. You might see some wires out of place or something like that.

Start the Macbook up holding the option key - When you're on the screen that displays your Macintosh HD boot volume see if the trackpad has functionality.

TheZTwin: I read a lot about the wires underneath the battery, but the unibody MB does not have any wires sticking out.

iamBATMAN: I tried this and now the problem is fixed (honestly have no idea why) but I am sure this is only a temporary solution as this has happened before.

Any ideas why is it happening and what can I do to fix it permanently?
