Hello everyone. I've got an Intel Core 2 Duo Macbook. It's about three years old now. I upgraded the ram and hard drive about two weeks after purchasing the laptop and it ran flawlessly for a year and a half. Suddenly, seemingly out of nowhere, the computer ceased to function. The computer would not turn on. When i plugged the mag safe connector into the machine the light would turn on, but it would be extremely dim. I reset the PMU, the SMC, everything. Removed the battery, unplugged the adapter, i did everything recommended by apple and simple internet searches. After this, I took it to an apple store where they checked the AC adapter and the battery but could find no issues. They tried a new ac adapter and battery but the computer would not turn on and the AC light was still dim. They concluded it was the logic board, i also had this "verified" through a third party mac repair shop as well. I did not spill anything on the computer and i had taken very good care of it as well so i wasn't sure where it had failed. With no money to buy a new logic board, the computer sat for many months and i was looking for thing to sell on ebay. I found the computer and begin messing with it again. Suddenly, it sprang to life as if it had never missed a beat. So, the computer and i go along for another year and now, about two weeks ago the same problem happens. I did a forced shut down when the computer froze up. I've done this several times, but this time it did not want to reboot. So now I'm back in the situation i was in before with the same issues. I've tried resetting all the control units i removed the ram and hard drive to reseat them all with no change to the "brick" status of the laptop. I curious if anyone has experienced this and if so, what am i to do to recover the machine and how to prevent it from happening again? Any leads or suggestions are very much appreciated. Thanks all for your time in advance.
