The DC power jack needs to be repaired. If you have a friend with a similar laptop, borrow his battery or bring your battery to him and install it in his laptop and let his laptop charge your battery. Reinstall the battery back in your laptop and see if it boots up. If it boots up you need to fix the dc jack.
