Not powering up, Green LED on Magsafe adapter, Battery indicator blink
I have 2.0Ghz A1286 MBP 15" and it is not powering up. I tried several MagSafe Adapters and it just lit up to GREEN and I tried to press the battery level indicator and all leds just blink. Is my magsafe board toast? or the whole logic board? Hope I can get an answer before I replace the wrong part.
Maybe try leaving it plugged in for a while, if the battery is completely discharged, then it will need to charge for a bit to be able to boot up. When you press the power button, does the sleep light in the front blink in any pattern, or can you hear fan noise/HDD noise coming from inside? This may help further diagnose the problem that is occurring, because it could be several things with the description that you gave us.
Hope this Helps
