I press the power button and the dashboard lights will go on for a bit but nothing else happens, the monitor wont even start and the computer gets locked with just the power led on, no HD activity. The video diagnostic was ok (using the d key while pressing the power button) but the diagnostic mode (Fn key while pressing power) will only give me all the lock leds on and the num lock led blinking. I tried using a AC direct power (no battery) and using a different AC and nothing worked. All devices were unplugged while performing this tests.
A flashing ON ON Lock LED sequence is indicative of a failed Motherboard
I am having the same issue... I have found its a defective GPU I got mine to work by removing the heat sink off of just the GPU and over heating it till the cooling fan turned back on... after the fan turned on I turned it off applied new thermal past and resetted the heat sink and it rebooted fine.

Thanks for the reply, i dont think i cant reset anything since it wont start or show anything on screen, its plainly dead, seems to me that the motherboard wont turn on but the computer itself seems to power on. A friend of mine said it could be the flex, could that be it? if so, is there a way i can test anything else to be sure?
bad motherboard, did u try reset the bios?
