Of all the components on your laptop computer, the laptop power jack repair is the most common. There are numerous factors that contribute to the high failure rate, but the two most common causes are due to bad design and poor handling. Over 90% of DC jackets are soldered on to the laptops motherboard.

The laptop will not accept the AC power adaptor and thus stays on til the battery runs out.

You have to constantly move and wiggle the powers cord around until it the laptop accepts the AC power adaptor.

The first thing that you should do is dispose of the faulty power cord. You should also check the power supply unit to see whether it’s functioning correctly. Most of these supply units have a power indicator light, to show when it’s plugged in. If the light is on, then it means the power unit is in good working order. If there is no light indicator then you’ll have to use a voltmeter, this can be done by plugging the laptop power supply unit into the wall socket and checking the end that connects to the laptop.

Make sure your voltmeter is set to read DC volts. If you receive a reading, depending on the laptop make and model, it should be anywhere between 14 – 19 volts, then your power supply unit is working fine, thus it’s your DC jack that is damaged.

Laptop power jack repair is a moderately difficult task. If you don’t feel up to the task, then it’s best you contact someone who’s qualified to do the job. In order to fix the jack, the entire laptop will need to be dismantled so that the motherboard can be removed.

When you have total access to the DC jack, you should notice the pins that are soldered on the motherboard. At first glance, it may appear as though there’s nothing wrong with it, but a partial break is capable of triggering this problem. You will need a finely tipped soldering iron. The fine tip on the soldering iron is so to prevent any harm to other components. Apply solder to every pin, using the iron eventually spread the solder across all the pins.

Once you’ve finished the laptop power jack repair and reassembled the laptop, make sure you test it, to see that it’s working correctly. In order to prevent this problem from ever occurring, take extra caution when inserting and removing your power socket.
