530U4C Not Charging

Hi, I have a 4 years old 530U4C laptop. Recently when i plugged in the power cable, the led indicator doesn't get on (neither green nor yellow light) and the laptop doesn't get charge. Sometimes it starts charging but then stops. I tried a different charger and the result is the same. The PC is working fine when it get charged, no problem there.
Can we say that the problem is the power jack?

 

As you have already tried a different charger, I agree with you that the next place to troubleshoot is the DC socket on the notebook. If this is soldered onto the board then it's possible that one of the connections between socket and board has broken (easily done if the cable is pulled sideways when the DC plug is in the socket which is why the better notebooks have the socket on a cable) which gives the intermittent connection. It might be possible to fix this by careful resoldering.

Thanks John,
as far as i see from the video below it is not soldered. I hope i can fix without any damage.

 

Good find, assuming that the 530U4C is basically the same as the 520U4C. That someone has produced a vidoe showing the replacement is an indication that it's a known problem. A quick look on ebay reveals that the part is reasonably priced.

I replaced it with a new power jack and it works perfectly now. It wasn't very difficult.
