No Power after replacing the Logic Board.
Just replace the Logicboard, put everything back together. (twice) and am getting no response from the macine at all. No lights, No hints of the macine trying to start, nothing at all. ? No memory itstalled, no Battery. When compared to a second macbook pro, I get a flashing white light, and optical drive makes a noise. It look like the first macine is not getting any power at all. Just tried a battery from another machin with some memory and got a white screen. So there is some life somewhere. Maybe the origial problem was not the logic board?
Esta é uma boa pergunta?

I do get a green light on Magsafe connection. With power on the battery, the machine will boot. However, no key board controll, other than the power button. I double check all cables, they seem tobe connected ok. I will reset the PRAM & NVRAM when I can get a keyboard working.
