    To be honest I didn't understand your posting very well.
    Can you please tell us what happen exactly when you press power button?

    What was your last action before you have noticed this problem?
    Have you updated BIOS or maye some hardware component?

    I' sorry, the problem is:
    1. The laptop turns on but no sign on and off at 30 seconds, you hear working hdd and off.
    2. Connect the power adapter and turn on only, no signs and off at 30 seconds!.
    3. When you turn the fan does not work.

    I tried:
    - Change Motherboard
    - Change the Memory
    - Change the fan cpu
    - I tried a different power adapter

    I hope your answers, thank you!

    > 3. When you turn the fan does not work.

    I think the notebook shuts down after 30 sec due to the high CPU temperature and this would be caused due to fan malfunction.
    Sorry mate but it’s difficult to say what’s wrong here… I would say its motherboard related issue but you have replaced the motherboard too so this makes the issue more difficult…

    Are you sure that the replaced motherboard is ok?

    Hi Tony, I'm not sure 100 per 100, bought by ebay, worked as the seller, the fan is new... what surprises me is that when I connect the power adapter switches itself on and not turn the fan!

    I have test the cpu is a intel i5 520M, so I can try a i3-370M, use the same network socket 988

    Why turn on only when I connect the power adapter?... I not know.., it's a shame!

    Thank You!

    That looks like motherboard or CPU issue… usually the fans should start rotating if an particular temperature level has been reached… so possibly some sensors on motherboard are faulty

    A test I did was remove the cpu, in this case does not turn alone! ... I have a cpu i3 370M, I'll pass on the motherboard to see if the cpu was what was wrong.

    Thanks for the help!
