Have you tried shorting the power pads?

This is the same function as pressing the power button.

@kas0 - With the battery disconnected, do it again this time hold the shorting for a good 10 secs. Then plug in your MagSafe did anything happen this time?

@danj Well i did try but nothing happend on that pins, however i did mange to find other and drain all the electricity from mbo, but it wont help they still wont turn on, seems is totaly dead

@kas0 - Looks like its time to swap out the logic board, but given the systems age you also likely need a new battery as well.

While I would love to see you keep you system going, the costs may not be economical.
