Hi, this lap top has droped from office desk and after that it power on but nothing on screen, no beep, nothing. I used hot air gun to resolder chips on motherboar. Now when I connect it od dc power with battery it charges battery and use about 2.5A of current. when I press power button current dorps to 0.07a and charging diode almost turns off but it shine just a litlle. Without battery it uses 0.07a of current and when press power button those diodes turns on but very low light and nothing happens.
I can't find schematics for this notebook ( msi pr200x, ms-12211) and don't know where to start. also pcb is very poor quality so I don't want to do unnecessary heating except if I know what to do.
thank you
