Hey I just $!^& blocked by this error today and tried some ways to fix this, first close the lid and insert the power plug to see the led light, the open the lid while the power plug is connected. Push and hold power button and Start button for 15 seconds. When in blinks white unplug the power cable. Don't do anything and wait for 1 minute, open the back door of the laptop and disconnect the battery then dismount the Ram. Wait for 1 minute. Reassemble the pcis and plug the power to the laptop without doing anything. Wait for 1 hour and then unplug the cable, now push the power button regularly. It worked for me.
