Dear hardware gods...

for the past two years my G53SW have had the common issue with the AC/DC Power jack (loose pin -> soldering gets knocked loose -> batteri wont charge) this has led me to replace the power jack on several occations. This became bothersome and expensive in the long run and for the past six months i have just reapplied the solder. i have never had any issues with the laptop afterwards but after my last surgical attempt i have been unable to power it on. The battery is fully charged and even with and without battery/powerchord i am unable to start it.
I have disassembled it twice now to check if i forgot to plug something back in, and im somewhat certain that everything is in place.

Does anyone have any clue as to what is going on with the laptop? i checked the forums/google and have found nothing similar to this and therefore no solution.

regards.

1. Solder does not get knocked loose if done correctly. Your equipment or soldering technique is flawed.
2. You should replace the dc jack when you have an issue with it (it's a $5 part, don't be cheap).
3. If you can't do it right the first time you need to pay a professional to do it for you.
There's absolutely no reason to be taking your laptop apart several times for the dc jack.

With all this said I think it's time you take it apart, remove the jack completely, clean up the holes/pads and check for damage. If you don't have any damage then you're lucky and you can install a new dc jack. If you do have damage to the pads you'll have to make sure the power is making a good connection.

This is a picture from a g73 I repaired that came from a forum member that took it to a computer shop for repair. Apparently the computer shop had "techs" that had no clue what they were doing. They ended up destroying a couple pads on the board and even burned the plastic for the vga connector.

The dc jack will still work correctly if you can get power and ground to the pins, I ended up soldering the dc jack from the top to make a good connection.

As you can see there's a good connection from the top of the motherboard and that's why I was able to repair the dc jack. You may have a similar problem. These so called "techs" didn't replace the dc jack and just kept adding solder, probably used a bit of force too because their equipment wasn't getting the solder joint hot enough. If you have this problem go find a professional, it's not worth the money for equipment and materials for one repair.

So my advice to you is to take it apart, remove the dc jack and let us know what you find.

Good luck.

thanks for the reply, it's probably both lack of skill and some crummy equipment. I would love to pay someone to do it, but i have found noone here (Denmark) who would/could do it for less than 600$ which was why i engaged in the project my self. I will reorder a new jack and try to repair it.

bought new solder equipment, and a new dc jack. Removed the old tin and scrubbed the motherboard with ethanol using a toothbrush. It looked great and i was able to apply the new jack. It's running smoothly so far.
