MacBook Trackpad Not working.

Hello,

Well I left my macbook alone for about 3 days in my room ,but today when I turned it on the mousepad/trackpad thing won't work. The keyboard works ,but I can't use the mouse. Any ideas on how to fix it?

What model MacBook or MacBook Pro do you have?

Got a USB mouse? Try rebooting and running Repair Permissions. Next step is checking the hard drive via the install DVD or Recovery depending on the operating system which you have no provided.

where do I go to run repair permissions?

will running the disk repair permissions delete any stuff on my mac

will it?

No, it won't. Don't worry.
