I screwed it again, its mechanicly dead now
The display wont turn on, and its not recognized by the windows
What did I do? I pressed and holded pins of memory here with my finger (u can lick it with tongue, not necessarily :P):

while holding it i runned upgrade software tool, and it worked :wink:
shame i screwed something while welding my battery back to its place, it will never work again it seems... :cry:
