MacBook died and will not charge or turn on

so a couple months ago i fell asleep listening to music on my macbook and woke up to it dead and not charging. no lights on the magsafe even turn on when i connect the charger and it's really got me bummed out because my mac pretty much has my life on it. anyways i've tried a couple of solutions and troubleshot online to no avail. i've tried the smc reset, i've opened up the back and disconnected the battery and did all that jazz and still didn't work. (one of the battery's is a little swollen but i've seen videos where people's battery's are extremely swollen and they still charge just fine) i know it's not the charger because it works perfect on my friends macbook and then plugged into mine it doesn't even light up like i've said. i've scrolled through like 10 pages of google and i had trouble finding anyone having this exact problem. anyways if anyone could help me that'd be GREAT and i would appreciate it a lot. thanks.
