Charger Faults
A dead light, damaged cable or burning smell all point to the charger. So does success with a borrowed charger. Replacing it is usually the cheapest fix.
Charging Fix Guide
Why Is My Laptop Not Charging? Charger, Port or Battery
You plug in the charger, yet the battery icon refuses to move. A laptop not charging quickly becomes a laptop you cannot use. Fortunately, the fault almost always sits in one of three places, the charger, the charging port or the battery. This guide helps you work out which one, using checks that take only a few minutes.

What You See
What Does Your Charging Problem Look Like?
Charging faults show up in different ways, and each pattern hints at a different cause. So start by noticing exactly what your laptop is doing.
For example, a laptop that shows no sign of power at all points towards the charger or the wall socket. Meanwhile, a message saying plugged in, not charging suggests the laptop sees the charger but is choosing not to fill the battery.
Slow charging is another pattern. It often means the charger is too weak for the laptop, which is common with borrowed USB C chargers. Finally, charging that only works at a certain cable angle usually points to a worn port or plug.
Once you know your pattern, the checks below will make much more sense. Keep a note as you go, because it helps a technician if you need one.
Common Charging Patterns
No power at all. No light and no charging icon.
Plugged in, not charging. Power arrives but the battery stays put.
Very slow charging. The percentage barely climbs.
Charges at one angle. Wiggling the plug changes things.
Stops at a set level. It never quite reaches full.
Quick Checks
Laptop Not Charging? Start With These Checks
Work through these in order. The early checks are free and solve a surprising number of cases.
Try Another Socket
Plug the charger straight into a different wall socket, skipping any power board. A faulty board or switched off outlet is an easy thing to overlook.
Check Every Connection
Many chargers have two cables, one from the wall and one to the laptop. Push both ends of each firmly into place. A loose join can cut power entirely.
Look for a Charger Light
Many charger bricks and plugs show a small light. If it is dark with a working socket, the charger is likely faulty. If it flickers, the cable may be damaged.
Inspect the Cable
Run your fingers along the cable, looking for kinks, frays or exposed wires. Pay attention to the ends, where cables bend most. Stop using any damaged charger.
Check the Port
Shine a torch into the laptop charging port. Lint and dust can stop the plug seating fully. Remove debris gently with a wooden toothpick, never metal.
Restart the Laptop
Occasionally, the power management system gets confused. A full restart resets it. Then reconnect the charger and watch the battery icon.
Try a Known Good Charger
If you can borrow the correct charger for your model, test with it. When a borrowed charger works, you have found the culprit.
Let It Cool Down
Many laptops pause charging when the battery is too hot. Move the laptop to a cooler spot, off soft surfaces, and try again after a while.
Windows Message
Why Does My Laptop Say Plugged In, Not Charging?
This message confuses plenty of people. It means Windows can see external power, but the battery is not taking a charge. Sometimes this is deliberate, and sometimes it signals a fault.
Battery Care Settings
Many laptop makers include a setting that stops charging at a set level to extend battery life. When it is active, the laptop shows this message once it reaches that level. Check the maker control app before assuming a fault.
An Underpowered Charger
If the charger cannot supply enough power, the laptop runs on it but has nothing left for the battery. This is common with phone chargers and small USB C adaptors. Use a charger rated for your laptop.
A Battery Driver Glitch
Open Device Manager and expand Batteries. Right click the entry described as the ACPI compliant control method battery and choose Uninstall device. Then restart, and Windows reinstalls it automatically.
A Worn Battery
An old battery may refuse to charge as a safety measure. Windows can generate a battery report that shows its remaining capacity. Our battery replacement page explains the next step if it is worn out.
USB C Charging Tips
Check the wattage
The charger must supply enough power for your laptop.
Use the right port
Some laptops only charge through specific USB C ports.
Match the cable
Some thin cables cannot carry full charging power.
Find the Culprit
Is It the Charger, the Port or the Battery?
Each part fails in its own recognisable way. Use these descriptions to narrow down your fault.
Port Faults
If charging depends on the plug angle, or the plug feels loose, the port is suspect. Ports wear with use and can break inside after a knock. Port repair is a common job.
Battery Faults
A laptop that runs fine on the charger but dies instantly when unplugged has a battery problem. Very short runtime and swelling are also battery signs.
Board Faults
Less commonly, the charging circuit on the main board fails. This happens after surges, spills or wear. It needs specialist testing and repair.
Settings and Firmware
Battery care limits and outdated firmware can stop charging early. Updating the BIOS from the maker website sometimes fixes charging bugs.
Heat Protection
When a battery gets too hot, charging pauses for safety. Blocked vents and summer heat often trigger this. It resumes once things cool down.
Battery Report
How Can a Windows Battery Report Help?
Windows can produce a detailed report about your battery. It takes a minute and removes a lot of guesswork.
Creating the Report
Open Command Prompt, type powercfg, then a space, a forward slash and the word batteryreport with no gap, then press Enter. Windows saves an HTML report in your user folder and tells you where. Open it in any browser.
Reading Design Capacity
The report compares design capacity with full charge capacity. Design capacity is what the battery held when new. Full charge capacity is what it holds now, so a large gap means heavy wear.
Checking Recent Usage
Further down, the report shows recent charging and draining. If long stretches show the laptop as plugged in not charging, a setting or fault is stopping the battery from filling. That detail is very useful to a technician.
Spotting a Dying Battery
Finally, look at the battery life estimates. When they have shrunk dramatically, a replacement is likely the answer rather than a new charger.
MacBooks
What If Your MacBook Is Not Charging?
MacBooks follow similar rules, although a few details differ. Try these Mac specific checks alongside the general ones above.
Check Optimised Charging
macOS may pause charging at a certain level to protect the battery. The battery menu shows when charging is on hold. This is normal and not a fault.
Try Each Port
MacBooks with several USB C ports can charge from any of them. If one port fails, try another. A single dead port suggests a port or board issue.
Check Battery Health
Open System Settings, then Battery, to see the health status. Service Recommended means the battery is worn. A replacement usually restores normal charging.
For Mac specific repairs, see our MacBook repair page.
Safety Warnings
Burning smell. Unplug immediately and stop using the charger.
Swollen battery. Stop charging and get help promptly.
Hot charger. Warm is normal, too hot to touch is not.
Cheap chargers. Unbranded chargers can be dangerous.
Prevention
How Can You Avoid Charging Problems in Future?
Most charging faults come from wear and tear. These habits reduce that wear and keep your laptop charging reliably.
Treat Cables Gently
Avoid wrapping the cable tightly around the charger brick. Instead, coil it loosely and avoid sharp bends near the plugs. Those ends take the most strain.
Unplug by the Plug
Pulling on the cable damages the wires inside. Always grip the plug itself. It sounds minor, but it adds real life to a charger.
Protect the Port
Avoid using the laptop with the charger plug under strain, such as on your lap with the cable pulled tight. Sideways pressure is the main cause of worn ports.
Buy Quality Replacements
When you need a new charger, choose one from the laptop maker or a reputable brand with the correct rating. Cheap alternatives may charge slowly, fail early or overheat.
Keep Things Cool
Charging creates heat, so give the laptop room to breathe. Hard surfaces and good airflow help both the battery and the charger last longer.
Getting Help
When Should You Get It Repaired?
If a known good charger does not help, or the port feels loose, it is time for professional testing. A technician can test the charger output, the port and the battery separately, then pinpoint the fault.
That testing avoids buying a new charger or battery you do not need. It also catches board level charging faults early, before they cause more damage.
Our laptop will not charge page explains common repairs, and the motherboard repair page covers deeper faults.
What to Bring
The charger. So it can be tested too.
Your notes. The pattern and checks you tried.
Any history. Drops, spills or storms.
Common Questions
Laptop Charging Questions Answered
Quick answers to what people ask most when a laptop will not charge.
Why is my laptop plugged in but not charging?
Common reasons include a battery care limit, an underpowered charger, a driver glitch or a worn battery. Check the maker settings and try the correct charger first.
How do I know if my charger is faulty?
A dead charger light, visible damage or success with a borrowed charger all suggest your charger has failed.
Can I use any USB C charger for my laptop?
Only if it provides enough power for your laptop. Weak chargers may charge very slowly or not at all.
Can a charging port be repaired?
Yes, in most laptops the port can be repaired or replaced. On some models, it is soldered to the main board, which needs specialist work.
Why does my laptop stop charging at a certain percentage?
A battery care feature is probably limiting the charge to extend battery life. You can change it in the maker control app or battery settings.
Is it safe to use a laptop that will not charge?
It is usually safe unless the battery is swollen or the charger smells burnt. In those cases, stop using it and get help.
Will a new battery fix charging problems?
Only if the battery is the cause. Test the charger and port first, because they fail more often than people expect.
Why does my laptop only charge when the cable is held at an angle?
That usually means a worn or damaged charging port or plug. Have it checked before the connection fails completely.
Summing Up
Power Restored, Stress Reduced
A laptop not charging nearly always comes down to the charger, the port or the battery. Simple checks, such as another socket, a close look at the cable and a borrowed charger, often reveal the answer quickly.
If Windows says plugged in, not charging, check battery care settings, charger wattage and the battery driver. Meanwhile, charging that depends on the cable angle points to the port.
Take safety seriously, especially with swelling or burning smells. If the checks do not solve it, professional testing will pinpoint the fault. For more help, see our common problems page.
Still Not Charging?
A local technician can test the charger, port and battery separately to find the real fault. You will know the fix before any work starts.
