hy,
i have motherboard mbx-189 water damage. after i repaired 3.3v 5v regulator laptop starts but green power light is blinking.
i changed the wpce775laodg and still same problem. after i changed the ICH laptop never power up.

i have another motherboard who worcked until i put the ICH form the first motherboard. i test it and laptop is powering on but no display.
i check the oscilators and at the first power on cristals are working. after a short time the motherboard is restarting and oscilators are not working anymore.
i want to start from Zero with tests. so tell me step by step what should i test.
