    Hello, I have a early 2009 macbook pro 13' unibody, it worked nice until yesterday, after power on, fan was going crazy and noisy, so I turned off computer and removed charger, when I tried tu turn it on again, there was not any signs of life, no stsrtup chord, fan or disc activities.

    What I have tried:
    disconnect and reconnect battery
    did SMC reset
    reconnect keyboard cable
    after that, I've removed logic board carefully, cleaned it with alchool, disconnect and reconnect any connectors, put everything back again, (I did everything very carefully) still no succss.
    when I connect charger, led indicator stays always green.
    Anything can advice me what can I do? there is no apple cary or anything left, as it's 2009 model.
    could it be mainboard problem? could it be dead?
    any advices please?

    Sounds like you have troubleshoot it pretty well. So unless you have the skills and tools to troubleshoot further you have two options. One, take the current unit into to a repair place, or two get another system.

    There is a possibility that you powered it off during a firmware upgrade. I say this because the fans ramp to full speed during install (pre-boot).

    Do you recall any updates related to firmware recently?

    My guess is that your assumption is right - it is the Logic Board.

    But if you really want to know, I believe it is free to take it to an Apple store and have them diagnose it at least (not sure if there is any 'product age limitation though'). I have done this before with a 7-yr-old laptop no probs.
