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?
