Quick answer
The most common causes are poor charger contact, a faulty adapter, a worn-out battery or a software driver issue. First check the cable and connector, then test another charger, and then check the battery status in the system; if the problem persists, replace the battery.
How to recognize the problem
- The laptop runs on power but the battery percentage does not increase
- The battery icon shows it is plugged in but not charging
- The battery charges only up to a certain percentage (e.g. 60%)
- The laptop shuts down immediately when you unplug the charger
- Charging starts and stops during use
Most common causes
Poor contact or damaged charger cable
The cable may be broken, and the connector loose or dirty. This leads to interrupted charging or charging only in a certain position.
Faulty adapter or charger
An adapter that delivers insufficient power or is partially faulty cannot charge the battery. Check that the adapter is original and of the correct power rating.
Worn-out or damaged battery
Batteries lose capacity over time, and cells can become unbalanced. The system then reports an error or charging stops at a certain percentage.
Software problem with driver or settings
An incorrect power management driver or an enabled charge limit feature can prevent charging.
Overheating or motherboard problem
When the laptop overheats, the system may stop charging for protection. Rarely, a fault in the charging circuit on the motherboard produces the same symptoms.
Step-by-step fix
- 1
Check the cable and connector
Unplug the charger from the power outlet and carefully inspect the cable along its entire length for bends and damage. Make sure the connector is clean and fits firmly into the laptop. Try charging with the cable in a different position and monitor whether the status changes.

Test another charger
If you have access to an original adapter of the same power rating, try it. The adapter must have the same voltage and at least the same current as the original. Do not use a lower-power adapter as it may overheat and will not charge the battery.

Check the battery status in the system
In Windows, open
Settings > System > Power & battery(the item name may vary slightly depending on the Windows version) and check the percentage and charging status. On macOS, click the battery icon in the menu bar or openSystem Settings > Battery. If it says plugged in but not charging, this indicates a hardware or software problem. - 4
Run the battery diagnostic tool
In Windows, open Command Prompt and type
powercfg /batteryreport. The report is saved as an HTML file at the path shown in the output; open it in a browser and look atDesign CapacityandFull Charge Capacity. If the latter is significantly lower, the battery is worn out. - 5
Update drivers and BIOS
Open Device Manager, find
Batteriesand update the driver forMicrosoft ACPI-Compliant Control Method Battery. Also check whether the manufacturer offers a newer BIOS or firmware for your model. Update BIOS only with the charger connected to power and do not interrupt the process. After updating, restart the laptop. - 6
Turn off charge limiting
Some laptops have an option to charge the battery only up to 60% or 80% to extend its lifespan. Check in the manufacturer's power app (e.g. Lenovo Vantage, Dell Power Manager, MyASUS) whether such an option is enabled and turn it off.
- 7
Calibrate the battery
Calibrate only if the manufacturer explicitly recommends it. The procedure varies by model and usually involves discharging to the level specified by the manufacturer and then charging to 100% while the laptop is off. Do not repeat it often, as deep discharge can damage the battery. Calibration helps the system display the percentage more accurately, but it does not repair a physically worn-out battery.

Check if the laptop is overheating
Clean the ventilation openings and check that the fan is working. Overheating can cause charging to stop. If the laptop is hot, let it cool down and try again.
- 9
Replace the battery
If the battery is more than three years old or the report shows significantly reduced capacity, replacement is the safest solution. Before replacement, turn off the laptop, disconnect the charger and, if possible, back up your data. Use an original or verified battery and follow the replacement procedure specified by the manufacturer.
If nothing helps
If you have tried another charger, updated drivers and checked settings, and the battery still does not charge, the problem is likely hardware. This could be a faulty battery, power connector or charging circuit on the motherboard. In that case, do not disassemble the laptop yourself, especially if it is under warranty. Contact an authorized service center with a description of the symptoms and, if possible, the saved powercfg /batteryreport report. The service can measure the voltage at the connector and determine whether battery replacement or motherboard repair is needed.
How to prevent it
- Use the original charger and avoid cheap replacement adapters.
- Do not leave the laptop charging on a soft surface that blocks ventilation.
- Periodically check battery health using the battery report.
- Avoid frequently fully discharging the battery to 0%.
When to call a professional
If you suspect a motherboard or power connector fault, or if the laptop is under warranty, it is better to contact an authorized service center than to disassemble the device yourself.

Why does the battery charge only up to 60%?
Most likely a charge limit feature is enabled in the manufacturer's app or in the BIOS. That option extends battery life but can confuse users. Check the power settings and turn it off if you want charging to 100%.
Is it safe to use the laptop while it is not charging?
Yes, if the laptop runs on power and the battery is not charging, you can use it. However, if the laptop overheats or charging is interrupted, it is better to turn it off and resolve the problem. Prolonged use with a faulty battery can strain the charging circuit.
How long does battery replacement take at a service center?
Battery replacement usually takes from 30 minutes to several hours, depending on the laptop model. If the battery is glued in or the entire laptop needs to be disassembled, the service may keep the device for up to one day.
