I have a 13" 2010 Macbook Pro which I am unable to boot. The most possible reason for it is that the Logic board has short circuited. I have detailed the problem in this separate post: Macbook Pro - Faulty keyboard short circuit at video connector
I am going to submit the laptop to service center but before that I need to take the backup of the data. Is it possible to do the backup? If so, how can I do that?
