I have an Asus ROG G51J. There was absolutely nothing wrong with it until the dc jack somehow got shoved back and the charger couldn't make a connection to it anymore. I have taken many laptops/desktops apart in the past and this was a simple fix. All I did was bend the dc power jack back to the right spot. It now properly charges and all the lights come on when plugged in and when I press the power button, the lights come on there properly as well, also. The lights all come on and the fan starts spinning but that's as much as it does now. The backlight doesn't come on, the display doesn't work, there are no POST beeps, nothing. I've tried swapping out the RAM. To get rid of variables I unconnected everything except the RAM. No hard drive, no wi-fi adapter, nothing. I've plugged the VGA into an external monitor. Nothing I've tried has gotten it to do anything more. I have a multimeter but I'm not really sure how to trace the power flow on a motherboard to make sure that power is being supplied to all the proper areas. I'm not really sure what to do next. Any help please?
