hi, guys! I have exact same problem than this one: https://www.youtube.com/watch?v=wAYMqr1zvoY but computer is lenovo, so the blinking led is on power and it's way faster.. should I try to reflow the motherboard in the oven or do you suggest anything else? I already power up, stripped down computer.. I also took motherboard out, disconnect everything including bios battery and just connect motherboard to adapter and it's still blinking.. adapter is fine without connection to motherboard it has normal voltage and the light on it is still.. but when I connect it, it jumps up and down, just like on the video.. thank you for any advice/help!
 
Solution
reflowing in the oven is used to temporarily fix GPU / NB issues. This barbaric method makes the laptop usable for about 24 hours if it works.
Power issues are solved by replacing the faulty chips on the power supply chain of the laptop. Meaning you have to use a soldering tool and a multimeter.
Now whoever told you that baking motherboards in the oven is a good idea was probably making fun of you.
For reballing chipsets you need a reball station and a bit of practice on some broken MB's.
