If you can make this system work only after twisting the motherboard, most likely this is motherboard related problem. I love breaking the manufacturers forced year engineered obsolescence cycle!!! There is a chance the new adapter is defective. Does the power LED flicker if you wiggle the power adapter plug inside the power socket? When I had used it the day before it was fully charged but I tried plugging in the cable to see what would happen and the charge light flashes on then off again. But once it starts it works fine as if there was no problem at all.
