This article will discuss how to fix a laptop charger pin if your laptop charger port is defective.
If your laptop charger port is defective, there are a few things you can do to try and fix it. First, check the pin to see if it is bent or broken. If the pin is bent, you can try to straighten it out with a pair of pliers. If the pin is broken, you will need to replace it.
Before you take some steps like purchasing a new pin or a charger see if you can fix the problem.
How to fix a laptop charger pin
There are a few reasons why a laptop is not charged, one is a loose connector or a damaged charging port. The deeper look will allow you to recognize the exact part to be replaced. Usually, it is the charger pin. But before you replace it, try to fix it.
– Check if the charging port is dusty, clean it with a can of compressed air.
– Inspect the charging port for any physical damage. If there are any loose wires, try to reconnect them.
You will need the following tools:
- A small screwdriver
- A needle-nose plier
- Some wire (preferably copper)
- Electrical tape
- Soldering iron and some solder (optional)
Detail
1. Disassemble the charger by unscrewing the casing.
2. Inspect the PCB for any signs of burning or charring. If you see any, then your charger is irreparable and you will need to replace it.
3. Locate the broken pin. It will be the one that is blackened or missing entirely.
4. If the pin is still partially attached, then you can try to bend it back into place with a needle-nose plier.
5. If the pin is completely detached, then you will need to solder a new one in its place.
6. To do this, first strip about 1 cm of insulation from the end of a piece of wire.
7. Then, at the end of the wire with a soldering iron and some solder.
8. Next, reheat the solder joint on the PCB where the pin was attached and touch the tinned end of the wire to it.
9. Hold the wire in place until the solder joint cools and solidifies.
10. Once the joint has cooled, trim the excess wire and tape it down so it doesn’t short anything out.
11. Reassemble the charger and try it out. It should now work properly.
If you have followed these steps and your charger still isn’t working, then it is most likely irreparable and you will need to replace it.
How To Identify The Issue
You need to identify why the laptop is not charging. The reasons include is a faulty charger or a spoiled power adapter or a cut cable as primary issues.
Check if the charger is using a multimeter. Set the multimeter to Ohms and check if there is a connection between the tip of the charger and the multimeter’s probes. If there is no continuity, then the charger is not working, and you need to buy a new one.
If you have verified that the charger is working but your laptop still won’t charge, then the problem is with your laptop. The next thing you should do is to check if the charging port is dusty or has any physical damage.
Deal with a Faulty Adapter
The adapter connects to the power outlet and provides power to charge the laptop. If it is not working, then the laptop will not charge. To check if the adapter is working or not, use a multimeter and set it to Volts DC. Connect the black probe of the multimeter to the ground (any of the outermost ports) and touch the red probe to each of the inner ports.
One of the ports will have a voltage that matches the adapter’s voltage (written on the adapter). If there is no voltage, then the adapter is not working, and you need to replace it.
If you have a loose port, wiggling the AC adapter plug could improve the connection and may help to charge your laptop.
First, unplug the power cord from both your computer and the wall outlet. Next, locate the charging port on your laptop. If there is any dirt or debris in or around the charging port, clean it off with a can of compressed air. Once the charging port is clean, plug the power cord back in and try charging your laptop again.
Deal With Broken Cables
Your cable for the charger may break down you don’t need to buy a new one. Just follow these quick solutions for broken cables:
If the Ac cables work fine then maybe the problem is in Dc Cable. The laptop charger is just a telling indicator of the problem. If you have a multimeter, you can measure the voltage at the DC input socket of the laptop with the charger disconnected and AC power on. The reading should be 19 – 21V. If it’s lower than that, then your adapter is bad and needs to be replaced. If you don’t have a multimeter, you can short the two DC input terminals of the laptop with a paper clip while the charger is disconnected and AC power is on. The reading is correct, then your adapter is bad. If you don’t get any reading, then check the fuse in the adapter.
IIn case if problem is with the AC cable, then you can check it by measuring the voltage at the AC output socket of the adapter with a multimeter. The reading should be between 100 and 240V. If it’s not, then your adapter is bad and needs to be replaced. Another way to test the AC cable is to plug it into a different outlet. If the reading is still the same, then your AC cable is bad and needs to be replaced.

What to do if Laptop Is Plugged In But Not Charging
1. Check if the charger is working or not.
2. Check if the charging port of your laptop is dusty or has any physical damage.
3. If you have a loose port, try to improve the connection by wiggling the AC adapter plug.
4. Check if the cables are working properly or not.
5. Try charging your laptop with a different outlet.
6. If none of the above solutions work, then there might be an issue with your laptop’s battery or motherboard. In this case, you will need to take it to a professional for repairs.
