DC jacks are the part of your laptop where you plug the power adapter in to charge. This is a very common piece of the laptop to get damaged because it it constantly being tugged at and pulled. If you are on the road and are constantly plugging and unplugging your laptop, there is a good chance that after 2 years, you will notice this jack start to act up.
Some common symptoms of a bad DC power jack are:
1. The computer is plugged in but it is not charging
2. If you wiggle the power adapter at the jack location, the computer goes from getting power to not getting power
3. The battery is not getting charged over night
4. the actual jack inside the computer is loose
In troubleshooting a bad DC jack, I tell my customers to first try a different power adapter. In rare cases, the power adapter is the root of the issue and the jack is fine. This is usually the cheapest fix because replacing the adapter is not that expensive.
I also suggest replacing the battery if it is over 2 years old. The battery has a life span and needs to be replaced every 2 years or so. If the battery is good and the adapter is good, your computer jack is most likely detached from the motherboard or broken all together.
Replacing the DC jack requires taking apart the whole laptop, soldering the jack that's in there, cleaning up the general area of solder and re soldering a new jack. Depending on the laptop, the job usually takes up to 2 hours and requires a surgeon's steady hand. The cost is usually around 0 for a good job and the jack will last the life of the laptop. You can find fly-by-night companies that do it for around 0 but the work is sometimes sloppy, they do not replace the jack with a new one and chances are the jack will not last the life of the computer.
