my laptop cq-40 126au also gave me problem few days ago, keep blinking 1 time. thought the cpu burn or something like that. i was so frustrated that i whacked it few times with my palm at the bottom part where the proc is being positioned and immediately it BOOTED!!!yes u heard me right it BOOTED!!!lolz! well maybe anyone who had this problem can have a try too coz there's nothing to loose but so much to gain right?
