If your laptop isn’t charging or the battery is draining quickly, there’s a good chance the DC jack is faulty and you need Dc jack replacement. The DC jack is the small port on the back of the laptop where the charger plugs in. In this guide, we’ll walk you through the steps to replace the DC jack on your laptop.
Before you begin, make sure you have the following tools:
- A screwdriver set
- Needle-nose pliers
- A soldering iron and solder
- A replacement DC jack
Step 1: Prepare the laptop
Turn off the laptop and unplug it from the wall. Remove the battery if it’s easily accessible. Then, flip the laptop over and remove any screws that are holding the bottom panel in place. Keep track of where each screw goes, as they may be different sizes or shapes.
Step 2: Open the laptop
Once you’ve removed all the screws, use a plastic pry tool or a credit card to gently pry the bottom panel off. Be careful not to use too much force, as you could damage the plastic.
Step 3: Locate the DC jack
The DC jack is usually located near the back of the laptop, where the power cord plugs in. It will be attached to the motherboard by a few wires.
Step 4: Remove the old DC jack
Use the needle-nose pliers to carefully disconnect the wires from the old DC jack. There should be three wires: one black, one white, and one red. Remember which wire goes where, as you’ll need to reconnect them to the new DC jack.
Next, use the soldering iron to remove the old DC jack from the motherboard. Heat up each of the metal legs until the solder melts, then use the pliers to gently lift the old DC jack off the motherboard.
Step 5: Install the new DC jack
Insert the new DC jack into the same spot where the old one was. Make sure the metal legs are aligned with the holes on the motherboard.
Use the soldering iron to heat up the metal legs of the new DC jack, then apply a small amount of solder to each leg. Be careful not to apply too much solder, as it could bridge the connections between the legs and cause a short circuit.
Step 6: Reconnect the wires
Once the new DC jack is soldered in place, it’s time to reconnect the wires. Use the needle-nose pliers to attach the black wire to the metal tab on the new DC jack, the white wire to the middle tab, and the red wire to the remaining tab.
Step 7: Test the new DC jack
Before you put the laptop back together, test the new DC jack to make sure it’s working properly. Plug in the charger and make sure the laptop is charging. If everything looks good, turn off the laptop and unplug it from the wall.
Step 8: Reassemble the laptop
Put the bottom panel back on the laptop and screw it in place. Then, insert the battery (if you removed it earlier) and turn on the laptop. If all went well, your laptop should be charging normally again!
