well , i have baught a second hand sony vaio model 2012 , everything seems to be fine until i start getting a sudden shutdown when i slightly shake the laptop , it is not a heat related problem i check the temperature it goes up to 55-60 c max and it is more likely to shutdown when i am on the battery than the ac adapter , but it does shut in the 2 cases , some friends suggest to check the hardware and maybe something is not well fixed into the motherboard . i am really lost i can't find the solution to my problem , please if you have any idea on how to fix it , i'll be glad .
PS : sorry for my english .
