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?

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.

Remove the battery and MagSafe adapter. Press and hold the power button for 10 seconds. This resets the SMC (System Management Controller). Replace the battery and MagSafe. Now reset the PRAM & NVRAM, here's how: http://support.apple.com/kb/ht1379

Check the connections with the Magsafe board. Is there a light on the Magsafe connection (red or green)? Do you have any power on your battery to check if you can start from the battery?

I also suspect you missed som cable to the top case. Try to take of the top case and start the machine by shorting the two pads close to the keyboard cable connector. It says "PWR" and you can short the two pads between the text with a small screwdriver. Let us know if this helps.
