Hi everyone, so here's the deal. I was using my macbook pro at a client, working fine. I put it in my back and head back to the office and one hour later when I go to wake it from sleep, I notice the pulsing light is not on. The battery still had a charge, so I tried turning it on and all that would happen is a brief blip of the white light and then it would power off. If I held down the power button, I would hear the DVD drive starting up but as soon as I let go, it would power off or if I held it long enough, the light would flash rapidly and then it would power off. I tried resetting the SMC controller, reseating the RAM, different RAM, and even taking the top case off to make sure no cables were loose. Any ideas? Anyone seen this behavior before? I'm just hoping it's not the logic board or AC board or something cause I'm not under applecare anymore... Thanks.
