We make sure that we buy a laptop that gives maximum time of battery life with a single charge. But sometimes, the battery drains fast. There can be two reasons, either your apps are way too heavy (in terms of MBs and GBs) or may be, your charger is faulty.
If the laptop is detecting charging with rotating the charging pin or bending of the charger on the either side or your laptop is not detecting the charger at all then there is a full chance that there is an issue with the cable, DC jack inside the laptop or connector. The question is, how do we know what is the real problem! Keep reading to find out.
But before we start the actual process and do analysis, you must know that most power jacks are directly soldered on motherboard, so this may not work for all brands of laptop and for such laptops, you have to heat up the soldering iron.
The first thing you have to know is how the laptop’s power jack communicates with a charger!
Most of the chargers’ work on two signals; GND and +VE but manufacturers like DELL, add an extra pin between those positive and negative connectors, so there are basically three connections in a single laptop jack. Now let us proceed to the solution.
Check Your Laptop’s Adapter
The first thing you have to do is check the DC, it may be damaged. Or you can check the adapter. It is easy to do, all you have to do is connect the charger with the main and check what is the output voltage. If you see proper voltage then there is a full chance that there is a problem with your problem. Now, we need to analyze what kind of problem is there.
Different problems can occur with the DC jack and following are the basic issues;
- The whole DC jack is damaged.
- The internal pin of the power jack is damaged.
- The DC jack is out of the laptop.
- DC jack is getting heated up or it is sparking.
- The laptop’s jack pins are moving on connecting the charger.
- The motherboard’s track is heated or burned that connects the jack with the circuit.
If the DC jack or the laptop’s jack is damaged then there is no solution to it, you have to get a new one. If someone says to fix it with a glue, then for some time, it can work but if an irregular power pulse reaches the motherboard, it can damage the motherboard and result in a dead laptop. Laptop jacks and DC jacks are easy to find. There are different ways to do it with different issues.
How to Fix Laptop Power Jack Without Soldering – Scenario 1
DC-in Jack consists of a separate connector for the motherboard. The first thing you have to do is get the connector out of the jack from the motherboard and now, connect the adapter to the DC jack. Now, check the voltage, it should not be showing any kind of voltage.
See the disconnected pin of the DC jack or the damaged wire and then join it and solder it. For reinforcement, you can use heat shrink tubes if you have any. Check the voltage again, since you made the connection, there should be some voltage. Reconnect and assemble the laptop.
How to Fix Laptop Power Jack Without Soldering – Scenario 2
In this case, you have to be very careful as you will be working on the motherboard. So, if the Dc jack is wobbling, to fix it, you have to apply flux on the whole pin of the jack and solder it again. And if any pins are damaged or the motherboard track is burned and first you need to find out which track is burned; GND or +VE or the sensing signal. If you have found out the burned track, then solder the wire directly on the location of the jack pin. Now, apply hot glue. Make sure that the hot glue does not get inside the DC-in connector and use thick copper wire to prevent burning.
