Here are some symptoms of a broken or loose power jack:
1. The laptop appears to be dead. Power LED and other LEDs will not light up when you plug the power adapter. Most likely in this case the power jack is broken and has to be replaced.
2. The power LED lights up only if you adjust the power plug inside the power jack, you have to wiggle a little bit. After a wile the power LED goes off and you can temporarily fix the problem by adjusting the power jack again. Most likely in this case the power jack is not making a good connection with the motherboard and has to be resoldered.
3. The laptop battery charges only when the laptop is off and the power adapter is plugged. When you turn on the laptop the battery stops charging. This scenario is similar to the example 2 and most likely there is connection issue between the power jack and motherboard. The power jack has to be resoldered.
