My Macbook Pro won't respond once turned on; the pad clicks but nothing is connected. Do I still have warranty for my model no. A1278/ N122Z844?
cursor won't connect to pad--or vice versa--short possible in pad?
MacBook, OS X Mountain Lion (10.8.4)
Since that number was used for 2009, 2010, and 2011 models, there is no way to know:

You have to check when you purchased it; you have a one year warranty or a total of three if you purchased Applecare.
