no sing of life

waspa, that's a mighty tall order. The very first thing that you should do is to stop trying to use your computer. Remove the battery. Download the service manual from here. remove your motherboard and clean it with 90%+ isopropyl alcohol and a soft brush. While you clean it, check for missing broken or charred looking components. Once it is all cleaned, reassemble your computer and replace the battery, then re-evaluate and see what you get. Any schematic will only help if you know how to read and follow it. You would also need to have the tools and the knowledge to perform board level repairs. Hope this helps, good luck.
