Thought it was my Logic Board... but not. What now?
I came home from work (where my MBP was working just fine), got home and started it up (not from sleep), but got no startup chime, sleep LED was on and the optical drive was running, but nothing else. I did some research and found out about the Nvidia chip problems and the logic board problems.
So I bought a brand new LB, which has the revised 8600 GT chip, (and according to the seller, was tested in a mac before being sold) and installed it today. I followed all the directions to the "T" from this website (THANK HEAVENS you are here) but when I got everything back together and attempted the startup. It exhibits the same symtoms.
It COULD be another bad board, but I also remember vaguely reading something here where someone mentioned it could be a bad left I/O board.
Well, I am not sure. The power adapter plugs in and it lights up green when the battery is charged, but is that amber color when it is not. so - I know it is charging the battery. Could it still be a bad left i/o board?
Thanks a million!

Is this a good question?
