In this guide, you’ll discover simple, step-by-step methods to determine whether your laptop charger is working or not. By the end, you’ll have the confidence to troubleshoot the issue yourself and potentially save money. Ready to get your laptop back in action? Let’s dive in!
Signs Of A Faulty Charger
Physical damageto the charger can cause it to stop working. Look for frayed wires, cracks, or bent plugs. These are clear signs the charger needs replacement. Damaged parts may create a safety risk too.
Pay attention to the charging indicator light. If it does not turn on or flashes strangely, the charger may have a fault. This light shows if the charger is delivering power correctly.
The laptop’s battery not chargingeven when plugged in often points to charger problems. The battery icon may show no change or a warning symbol. Test the charger with another laptop if possible to confirm.

Visual Inspection Of Charger
Check the power cordfor any cuts or tears. Make sure the adapteris not cracked or swollen. These signs may mean the charger is damaged.
Examine the connectionsclosely. Loose connections can stop the charger from working. Wiggle the cord near the adapter and plug. If it feels loose or moves easily, the charger might be faulty.
- Ensure the plug fits snugly into the wall socket.
- Look for any bent or broken pins on the charger plug.
- Check if the LED light on the adapter turns on (if available).
Test With Different Power Outlet
Try plugging the charger into a different power outlet. Sometimes, the outlet may have no power. This check helps find out if the problem is with the charger or the socket.
Use outlets in different rooms or buildings to test. Be sure the outlet is working by plugging in another device.
If the charger works in another outlet, the first outlet may be faulty. If it does not, the charger might be broken.
Keep an eye on the charger light. It should turn on when connected to a good power source.
Use A Multimeter For Voltage Testing
Set the multimeter to the correct voltage range, usually DC volts. Check the charger label for its output voltage. Connect the multimeter probes to the charger’s output plug carefully. The red probe goes to the inside pin, and the black probe touches the outside metal part.
Read the voltage on the multimeter screen. It should match the number on the charger label. Small differences are okay, but big gaps mean a problem. If the voltage is too low or zero, the charger might be broken.
| Charger Specification | Multimeter Setting | Expected Reading |
|---|---|---|
| Output Voltage (e.g., 19V) | DC Voltage, 20V range | Close to 19V |
| Output Current (e.g., 3.42A) | Not measured here | Not applicable |
Try Another Compatible Charger
Trying another compatible chargerhelps check if the original charger is faulty. Use a charger with the same voltageand connector type. This ensures safety and proper power supply.
Plug the other charger into the laptop. If the laptop charges, the first charger is likely defective. If it still does not charge, the problem may be with the laptop’s charging port or battery.
- Check charger specifications before using another one.
- Do not use a charger with different voltage or wattage.
- Test the laptop with the alternative charger for a few minutes.

Test Laptop Battery Status
The battery iconon your laptop shows the charging status. If the charger works, the icon shows a charging symbolor a plug sign. If it does not, the icon may show no chargingor a warning sign.
Use battery diagnostic toolsto check the battery health. These tools give detailed info about the battery and charger. They can tell if the charger is delivering powerproperly or if the battery is not charging.
- Open battery settings to see the charging status.
- Run battery diagnostics from the system or third-party apps.
- Check for error messages related to charging.
- Observe if the battery percentage increases when plugged in.
Inspect Laptop Charging Port
Check the charging portfor any debrislike dust or dirt. These can block the charger from connecting properly. Use a soft brush or compressed air to clean it gently.
Look closely for any damagesuch as bent pins or cracks. Damaged ports may stop your charger from working.
- Try the wiggle test: move the charger plug slightly inside the port.
- If the charging light flickers or goes off, the connection might be loose.
- A loose connection can mean the port or charger plug is worn out.
