How to Identify a Broken Laptop Charger

The first step to fixing your broken laptop charger is to accurately diagnose the issue. Some common signs of a faulty laptop charger include the charger not powering on, the laptop not charging or charging slowly, the charger getting hot, exposed wires near the tip, bent pins, and physical damage. Here are some specific things to check:

Checking for Physical Damage

Inspect your laptop charger for any visible damage like cracked plastic, bent pins, frayed cords, or exposed copper wiring. Damage to the charger casing or tip often indicates an internal component failure.

Using a Multimeter to Test Voltage

Use a multimeter to check the voltage output from the charger. Plug it into the wall and then touch the red and black probes to the inner and outer pin on the charger tip. It should output around 19V. If the voltage is incorrect or unstable, the charger needs repair.

Determining Connectivity Issues

Check that the charger securely fits into your laptop port without any looseness or intermittent connections. Wiggle the tip while plugged in to see if charging cuts in and out, which would indicate damage to the port or poor pin contact.

Assessing the Power Cord

Examine the entire length of the power cord for damage and test bending the prongs to see if the cord loses power. Frayed, torn, or loose cabling can cause charging issues.

Inspecting the Laptop Charger Port

Issues like bent or broken pins in the laptop’s charging port itself can prevent making solid contact with the charger. Use a flashlight to look directly at the port pins for any damage or obstructions.

Repairing a Broken Laptop Charger Tip

The most common part of a laptop charger to break is the tip where the cable connects to the plug that goes into your laptop. Luckily, these tips can often be repaired or replaced cheaply and easily.

Replacing the Charger Tip

If the damage is beyond repair, you can buy just a replacement charger tip online for around $10-15. Match the tip to your make and model of laptop like Dell, HP, Lenovo, etc. Swap the new tip onto the existing cable.

Fixing Exposed Wires

If there are any inner copper wires poking out from cracked plastic, wrap them tightly with electrical tape so they don’t touch anything. This will prevent shorts or shocks while using the charger.

Soldering the Connector

For loose tip connectors, carefully pry open the plastic housing and re-solder any disconnected wires to the pin connectors inside. This will renew the power connection.

Using Electrical Tape for Temporary Fix

In a pinch, tightly wrapping the damaged section in overlapping layers of electrical tape can help hold things together and prevent exposed wires. Just be careful not to let tape interfere with the metal charging pins.

Assessing the Laptop Charger Pin

If your charger tip pins are bent or broken, gently straighten or remove them with pliers. If pins are damaged beyond repair, you may need to replace the entire tip or connector end.

DIY Solutions for a Broken Laptop Charger

If you determine the issue lies in the charger box or cable, here are some DIY ways to troubleshoot and fix internal problems before resorting to replacing the whole charger.

Disassembling the Charger

Carefully take apart the charger casing and inspect the internal wires, solder points, circuit board, transformer, and other components for damage. Re-solder any loose connections.

Identifying Internal Connector Issues

Problems with the connector cables inside the charger can prevent power output. Track wiring issues back to the source and repair connections.

Testing the Charger Adapter

Use a multimeter to test output directly from the adapter plugged into an outlet without the cable attached. If voltage is abnormal, the adapter likely needs replacement.

Checking for Loose Screws

Open up the charger casing and ensure no internal screws are loose that could be interrupting electrical connections and causing intermittent power.

Unplugging and Reconnecting the Charger

For chargers that only work in certain positions, there may be a partial internal break. Unplug and firmly reconnect internal connectors and wires.

Preventive Maintenance for Laptop Chargers

Practicing proper laptop charger care and maintenance can help avoid breaks and extend the charger’s lifespan.

Properly Winding the Power Cord

Don’t wrap the cord tightly around the charger box. This can stress the internal connections. Instead, loosely wind cords to prevent fraying and damage.

Using a Surge Protector

Plug your laptop and charger into a surge protector to protect from power spikes that can damage charger components and electronics.

Cleaning the Charging Port

Regularly use compressed air to blow out any dust and debris that may accumulate in the charging port and prevent proper charger contact.

Avoiding Overloading the Adapter

Don’t overload your charger by using high-draw devices other than your laptop. This can overheat and fry the adapter.

Ensuring a Secure Socket Connection

When plugging in your charger, push firmly to have a tight connection with the socket to avoid arcs, sparks, and damage over time.
