Will not boot, no startup sound, dead but charges battery
This is a 17" MBP A1212 2.44Mhz. There is no startup sound. Nothing happens when I press the power button. The MBP charges the battery. No chime, no light, no fan, complete silence. I tried the reset PMU, changed RAM to make sure and about every trick Mayer suggests on other similar topic. Have no idea where to start! Can it be the DC-in board even if the battery charges?

Thanks. The computer is already shut down since it does not start up. I cleaned and reseated the keyboard to logic board cable. It does not seem to react at all to the power button.

I opened the MBP and found the "PWR BTN" connector and shorted that with a screwdriver. Then it started up normally. There is no reaction from the keyboard whatsoever. Not from the mouse, keyboard or power button. I was able to connect a USB mouse and keyboard and they work fine. How do I fix my keyboard problem?

There has been no liquid spill on it. The Magsafe lights normal, the battery charges fine.

Any idea as to how I can check the keyboard. There is no response from the keyboard, trackpad or power button.
