How To Fix A Laptop Charger Port- A Step By Step Guide

How To Fix A Laptop Charger Port

It is possible to fix a laptop charging port via a step-by-step approach. The first step is to identify the source of the problem. For instance, if the head of the problem is a power jack connected to the computer’s motherboard, you can remove the faulty jack and replace it with a new one. If, on the other hand, the power jack soldiers to the motherboard, you will have to remove the soldiered jack before replacing it with a new one.

Identify The Problem Source

Broken charger ports on laptops are some of the most typical issues handled through computer repairs in Brighton . Just before you do any repairs, you need to troubleshoot the problem and identify its source. Some of the main reasons why a laptop charger port has become faulty are; faulty power adapter, faulty battery, and cut cables. If it is not one of these significant culprits, you may have to seek the help of a professional technician.

You must check first if the charger is supplying the right voltage with a multimeter. If the charger is providing the proper voltage, then the issue may likely be with the battery. If this is indeed the case, you may need a battery replacement to resolve the issue.

If the laptop’s power adapter is not supplying the right voltage or power is not coming from the adapter, then the issue may arise from faulty cabling.

How To Fix A Charger Port That Is Not Working

For complex charger port issues, you may have to disassemble your laptop. It would help if you had a thorough examination of the problem to identify the specific parts that need to repair.  If you can’t figure out the source of the problem when troubleshooting, contact a technician for help.

If the charging port’s damage is severe, get your prongs and a screwdriver to reset the port connectors to their original shapes. If you don’t have a screwdriver, you can use Tweezers for the same purpose.

If the issue is from a faulty adapter that connects to the primary electricity source via a plug, you will need to find a replacement charger. It would be best if you handled adapter cases with utmost care to avoid accidental electrocution.

If you know how electrical circuits work and take appropriate precautions, you should be able to fix adapter issues yourself.  Switch off the power before removing the charger from the outlet.

Since most power adapters for laptops are housed inside a plastic case and sealed with a super adhesive, you may have to pry the plastics open forcefully. To do this, run a sharp knife or a screwdriver in the middle where the two plastics separates to break that seal. Once the seal has open, pull the charger apart to gain access to the internal components.

Now that you have access to the inside, you will see a motherboard and transistors plus capacitors. Please pay attention to the capacitors because they have become swollen, causing damage to the adapter. Buying a new capacitor of the same capacity is the only way to resolve this issue.

You may also want to check the cables’ integrity and ensure that there are no breakages within. While checking the cables, make sure you don’t touch the PBC board while the adapter is still connecting to the AC power source. If there is an issue with the DC cable outlet, change it at this stage.

When checking the adapter, you must avoid interchanging the positive with negative current outlets. Your laptop battery won’t charge if you make this mistake.

Fixing Broken Cables

The cable in your laptop charger will eventually weaken at some point, creating issues with the laptop charger port. If you are lucky to have a laptop adapter that comes with a glowing LED indicator to show if power is flowing through adequately, you can easily suspect broken cables.

If your adapter’s LED lightens up when connected to the mains electricity supply, there is an issue with the DC output cord.

If your Adapter’s LED is not lighting up at all, check the AC power cable with your voltmeter to ensure there is no output voltage. If your AC cord is not providing sufficient power, the issue may arise from a broken fuse, damaged plug, or some cut wires- try and figure this out. Whatever the issue is, it is quite cheap to replace a broken fuse, cut wires or damaged plug.

If your AC cable is in good working condition, then the issue will likely arise from DC outlet cable or adapter. A sign of faulty outlet cable is when your laptop charges only when you move or place the laptop a certain angle. The charging cord might have been broken from the inside and requires a replacement.

Laptops that have “L” connectors are less prone to damage, same with laptops that come with robust cables. Once you have discovered the faulty component, simply cut along the cord and you may have to shave the choke. Be careful with the sheath of the plastic cover too.

Make sure you connect the connectors with appropriate wires to resolve issues with cords.  You don’t have to replace the whole adapter with this simple repair steps. You need to confirm that these connectors are properly connected to the right wires.
