I need help with a laptop (Asus G51J)

[shaynec1981]

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?

I know that motherboard and the DC jack. How exactly was it bent ? I mean really exactly in which direction and how much. That jack really can't be "bent" back and forth unless you mean it came up out of its soldered points on the motherboard. There is also a brace plate under that jack area which may be shorting with something.

Also did you check all the circuits around the DC jack or anywhere you touched it after you were done?

At this point it could be anything and I think you are looking at a total tear down again. To test things as you go in or to at least check out the board for anything obvious you might have damaged.

It was shoved directly back. Like too much pressure had been applied inserting the power cord and over time just recessed back. Best way I can think of to explain it.

Well, I'll take your word for it but the way that jack is designed I don't see how the whole jack can be just forced backwards and how you can just force it back to normal.
