Visual Inspection
Check the power cordfor any cuts, frays, or bends. A damaged cord can stop power flow. Make sure the cord is firmly plugged into both the wall socket and the charger brick.
Look closely at the charger brick. See if it has any cracks, burn marks, or loose parts. A damaged brick might not work properly or could be unsafe.
Inspect the connector tipthat plugs into your laptop. It should be straight and clean. Bent or dirty tips can cause charging problems. Wiggle it gently to check for a loose connection.
Test The Power Outlet
Check the power outlet by plugging another device into it. This helps to confirm if the outlet has electricity. Try different sockets in the room to see if the laptop charger works in any of them.
- Use a lamp or phone charger to test the socket.
- If the other device works, the outlet is fine.
- If not, the outlet might be the problem.
Using another device is a simple way to check power flow. This step saves time before testing the charger itself.
Check For Indicator Lights
Most laptop chargers have a small LED lightthat shows power status. When plugged in, this light should turn on. A bright, steady lightusually means the charger works well.
Some chargers use different colorsto show status:
- Green or whitemeans charging is normal.
- Orange or ambermeans the laptop is charging but battery is low.
- No lightmay mean no power or a broken charger.
The laptop itself often has a charging indicator light. This light turns on when the charger works and the battery is charging. If both charger and laptop lights stay off, the charger might not work.

Listen For Sounds
Buzzing or humming sounds from the charger can show it is working. A faint noise means the charger is getting power. No sound could mean no power or a broken charger.
Unusual sounds like crackling or loud buzzing are a bad sign. These noises may mean the charger has a problem inside. It might be unsafe to use. Stop using the charger if strange sounds happen.
Listening closely to these sounds helps check the charger without tools. Always plug the charger into a safe outlet before listening. Be careful not to touch metal parts while testing.
Feel For Heat
Touch the charger after it has been plugged in for a few minutes. A slight warmthis normal and shows it is working. If the charger stays cold, it might not be sending power.
Watch for overheating signslike extreme heat or a burning smell. These signs mean the charger could be damagedor unsafe. Stop using it immediately if this happens.
Feeling warmth helps check if the charger is functioningwithout special tools. Just be careful not to touch it for too long.

Use A Spare Charger
Test the laptop charger by using a spare chargerfrom a similar laptop. Plug the spare charger into your laptop and see if it charges properly. This helps to check if the issue is with your original charger or the laptop itself.
Compare how your laptop behaves with both chargers. Look for these signs:
- Charging lightturns on
- Laptop battery percentageincreases
- Laptop runs without batterywhen charger is plugged in
If the spare charger works well but your charger does not, the original charger is likely faulty. If both chargers fail, the problem might be with the laptop’s charging port or battery.
Check Battery Response
Check the battery iconon your laptop screen. When you plug in the charger, the icon usually changes. It may show a charging symbolor a lightning bolt. This change means the laptop is receiving power.
Try to turn on the laptopwhile it is plugged in. If the laptop powers on or stays on longer, the charger is working. If the laptop does not power on or the battery icon stays the same, the charger might be faulty.
Try Basic Voltage Testing Tools
A USB voltage testerhelps check laptop chargers easily. Plug the charger into the tester and watch the display. It shows the voltage output. If the number matches the charger’s label, it works well.
A simple LED testeruses small lights to show power flow. Connect the charger to the tester’s leads. If the LED lights up, the charger is sending power. No light means a problem.
- USB voltage tester: Shows exact voltage output.
- Simple LED tester: Lights up to indicate power flow.
