I bought a macbook pro on eBay (non-working) hoping I can fix it. I took the entire thing apart cleaned the board and keyboard. I saw no visible water damage and no visibly damaged components. I bought a new battery for it, the battery appears to be charging. The power adaptor glows orange as the batter charges and green when it's charged or running off ac adaptor only. I was able to boot the computer one time using the reset SMC procedure I found on a thread here, but I am not able to duplicate the boot. I am able to measure correct voltages (based on information from the same thread) at the power on pads (but not able to boot when shorting these) I'm at a loss. Thanks in advance.
