Jump start my Mac Book pro

Hi,

I have a Mac book pro 15 inch which I have been working with for the past 6 month without encountering any problems and all of a sudden just like that it just turned off all by itself and I can't even turn it back on. All my work is in it And I am completely desperate could someone help me on this please....?????

First try resetting the System Management Controller (SMC)

Intel-based Macs: Resetting the System Management Controller (SMC)

I tried all the options of reseting the smc but didn't work. The only one I didn't try was the one in which I would have to remove the battery which I can't because I don't have the right screw driver.

Is it still under warranty?

And trust you do have an external drive and everything is backed up?
