    ok, i went to the bathroom, and i was in there 10-15 minutes, and when i came back my laptop was completly dead
    no lights no nothing
    and i can see that the lights on the charger is blinking like something has shorted insede the laptop,
    i have taken my laptop completly apart, ive done this a few times on other laptops,
    but i dont see any burned transistors or anything,
    so any help would be appreachiated, i will try the oventrick with it, as i have tried with other boards and have worked

    Does it work on battery power?
    Can you check with another PSU and without the battery?

    yes i broke one of the legs, so i had to change it anyway

    has this number on it 1J03SH, and i cannot find it anywhere on the internet, so i just took one from an old motherboard. changed it and it does the same, the charger blinking
    then i felt around the motherboard and i could feel that there was something else that got really hot,

    dont worry this is the motherboard i took it from.
    i took and changed that and tada, power to the laptop, yay i thought, but now it does not post, it turns on, then off and the automaticly on again and then its just on, nothing
    i have no idea of how to know if they are turned the right way, lol



    YES ITS ALIVE ITS ALIVE MUHAHAHAHA
    i just hit it a few times after i changed the things above, and pushed the power butten,
    im sooo happy right now :D
