Re: copmaq cq40 no diosplay

if you don`t own a $$$ station i`ll suggest to try a NON pro way.
cook the whole board.

Re: copmaq cq40 no diosplay

if cooking doesn't help, wash it make sure remove cmos battery first. you can put it under the sun afterwards

uneven heat could deform the cpu socket. make sure you have elstein ceramic up and down to do it.
its better to reflow cpu socket than reball it, if this is your first time.
