Suspecting the logic board at this point. Does this computer has one of those reset button's on the logic board to reset the PRAM?
Could that be an option for its symptoms?
Seems to be getting power, RAM is known to be good.
No chime and otherwise dead.
Any advise will be appreciated!
Thanks
Rico

We may have to try several things. First let's reset the Power Management Unit:
How to Clear the PMU 1. Step 1 Quit all of your active applications and shut down your Mac. 2. Step 2 Once your computer is completely shut down, disconnect the computer's AC power Adapter and remove the battery from your Mac. 3. Step 3 Press and hold down the power button on your MacBook or MacBook Pro for at least five seconds and then release the power button. 4. Step 4 With your Mac still shut off, reinstall the battery in your MacBook or MacBook Pro and reconnect the AC Adapter. The PMU/SMU has now been reset on your computer.

Next try resetting the PRAM. Start up and immediately hold down the option - command and the "P" & "R" keys. Wait till you hear three tones, then let it try to start up.
Good call. +1 Ralph
