The MacBook has the green light but doesn't turn on.
I have a macbook pro that i got that I am trying to trouble shoot, the issue is that when you press the power button nothing happens, no fans, no hard drive spin up, no sound, like it has no pwoer, however, the LED on the MagSafe adapter turns green when plugin, the battery has 1 light that flashes when pressing the test button, I left it plug in with the battery for a few hours and still the battery has the 1 flashing light.
I have re-seat all the cables on the logic board, short the contacts on the logic board for the power button in case it was that, but that didn't work, what I am trying to figure out if this means its something on the logic board or the left I/O board, is there any way to tell this, maybe testing the voltage outputs from the I/O board to the logic board?
It is a 2.4 GHz Core 2 Duo EMC No: 2136 which I believe is the late 2007 model, it has the nvidia GPU.
