Sorry if (if?) this is bad news, but I have replaced motherboards on  
several A series which were doing the same thing.
The new MBs completely solved the problem.

Point to ponder:
"Thin is in" should not apply to laptops.
As the base unit gets thiner it is less able to resist the twisting of 
the case and sooner or later
internal connections on the motherboard will break
I make it a habit to never pick up a laptop with one hand and even then 
I grab it close to the
back near the hinges or in the middle ( on both sides ) if the battery 
is in place.
The less flexing the better.
