In this guide I remove the motherboard and repair the DC power jack in a Dell Inspiron B130 laptop. You can use same instructions for Dell Inspiron 1300 and Inspiron B120 laptops. All three models have same type of body.

In my case the power jack started failing intermittently. The laptop started switching from AC to battery power on its own. In order to switch it back to the AC power I had to fiddle with the adapter plug and find the right position. I tested the laptop with another adapter and it failed exactly the same way. I came to a conclusion that the DC power jack is not making good contact with the motherboard and has to be repaired.

In Dell Inspiron 1300/B120/B130 laptop the DC power jack is soldered to the motherboard. If the jack is broken, you’ll have to unsolder it and replace with a new jack.

Let’s start removing the motherboard.
