if your battery has charge, and the device wont even show a sign of life, you likely need a logic board replacement. unless you have a background in board troubleshooting, and can find/repair the failure on the board itself.
If it is not getting power then I would start with the ac/dc jack on the laptop.You can start with a muttimeter by measuring resistance and making sure you are getting a good connection. This jack seems to be soldered to the board so replacing it may take some elbow grease. Testing the Jack Here is a video on how to disassemble Update (01/09/2018) Here is a video on desoldering the old jack and adding a new jack to the board.
