Is your laptop plugged in but the battery is not charging? Perhaps Windows shows “Plugged in, not charging,” the battery percentage stays the same, or the laptop works only when the charger is connected.
This problem can be caused by a faulty charger, a damaged charging port, battery wear, incorrect power settings, or a software issue. Fortunately, there are several troubleshooting steps you can try before paying for repairs.
In this guide, you will learn how to fix a laptop battery that is not charging, how to identify common causes, and when to seek professional help.
Why Is Your Laptop Battery Not Charging?
Several issues can prevent a laptop battery from charging properly:
- A damaged or incompatible charger
- A loose or faulty charging port
- An aging or worn-out battery
- A temporary power-management problem
- A battery charge limit enabled by the manufacturer
- An outdated or malfunctioning battery driver
- Overheating or a hardware fault
Some laptops intentionally stop charging at a certain percentage to preserve battery health. Therefore, a battery that stops at 80% is not necessarily faulty.
1. Check the Charger and Power Outlet
Start by checking whether your laptop is receiving power correctly.
- Disconnect the charger from the laptop.
- Check the wall outlet using another suitable device.
- Inspect the charger and cable for visible damage.
- Reconnect the charger securely.
- Check whether the laptop’s charging indicator turns on.
- Wait a few minutes and check the battery percentage again.
If your laptop uses USB-C charging, make sure the adapter and cable support the required power output. Not every USB-C charger can supply enough power for every laptop.
Never use a charger with exposed wires, burn marks, or signs of electrical damage.
2. Restart Your Laptop
A temporary software or power-management issue may prevent Windows from displaying the correct charging status.
To restart your laptop:
- Save your work.
- Open the Start menu.
- Select Power.
- Click Restart.
- Wait for Windows to load.
- Reconnect the charger if necessary and check the battery status.
A restart may resolve a temporary issue, although it will not repair a damaged charger or worn-out battery.
3. Check for Battery Charge Limits
Some laptop manufacturers provide battery health features that limit charging to around 60%, 80%, or another selected level.
These features are designed to help reduce battery wear when a laptop spends much of its time plugged in.
To investigate:
- Open your laptop manufacturer’s battery or power-management application, if installed.
- Look for battery health, charging limits, or battery conservation settings.
- Check whether a charge limit is enabled.
- Review the manufacturer’s instructions before changing it.
The name of this feature varies by manufacturer. If your laptop consistently stops at a particular percentage, a charge limit may explain the behavior.
You do not need to disable battery conservation features unless you specifically need the battery to charge further.
4. Let the Laptop Cool Down
Excessive heat can affect charging behavior. Some laptops temporarily limit or stop charging when the battery or system becomes too hot.
Try the following:
- Disconnect the charger if the laptop is unusually hot.
- Close demanding applications.
- Place the laptop on a hard, flat surface.
- Keep ventilation openings clear.
- Allow the laptop to cool naturally.
- Reconnect the charger and check the battery status.
Do not place the laptop in a refrigerator or use ice to cool it. Sudden temperature changes and condensation can damage electronic components.
If the laptop repeatedly overheats, seek professional inspection.
5. Check the Charging Port
A loose or damaged charging port can prevent a laptop from receiving power reliably.
Look for obvious signs of damage around the port. Connect the charger gently and check whether the charging indicator appears.
If charging works only when the cable is held at a particular angle, the cable or charging port may be faulty.
Do not force the connector into the port or insert metal objects to clean it. If the port is loose, damaged, or unusually hot, stop using it and arrange a repair.
6. Check the Battery Status in Windows
Windows provides information that may help you investigate battery problems.
You can generate a battery report on supported systems.
- Open the Start menu.
- Search for Command Prompt.
- Open it.
- Enter this command:
powercfg /batteryreport
- Press Enter.
- Follow the displayed file location to open the report in your browser.
The report may include the battery’s design capacity and estimated full-charge capacity.
If the full-charge capacity is significantly lower than the design capacity, the battery may have experienced substantial wear. However, the report alone does not prove that the battery is defective.
If Windows cannot generate the report, the battery or device may not support all the report features.
7. Update or Reinstall the Battery Driver
A Windows battery-driver problem can sometimes affect how battery status is reported.
To inspect the driver:
- Right-click the Start button.
- Open Device Manager.
- Expand Batteries.
- Look for entries such as Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery, if present.
- Right-click the relevant entry and select Update driver.
If updating does not help, you may consider uninstalling the battery device entry and restarting Windows so it can detect the device again.
Only uninstall the relevant battery device entry, not unrelated hardware. If you are unsure, check your laptop manufacturer’s support instructions first.
8. Install Windows Updates
Windows updates can include fixes for device compatibility and power-management problems.
To check for updates:
- Press Windows + I.
- Select Windows Update.
- Click Check for updates.
- Review available updates.
- Install appropriate updates.
- Restart your laptop if prompted.
For model-specific power or chipset drivers, check the official support website of your laptop manufacturer.
Avoid downloading drivers from unknown websites.
9. Perform a Manufacturer-Recommended Power Reset
Some laptops support a power reset that can help resolve temporary hardware-control problems.
The procedure varies by model, so check the manufacturer’s instructions before attempting it.
A general procedure for models that support it is:
- Shut down the laptop.
- Disconnect the charger.
- Disconnect external accessories.
- If the battery is removable, remove it according to the manufacturer’s instructions.
- Follow the manufacturer’s recommended power-button reset procedure.
- Reconnect the battery and charger as instructed.
- Turn the laptop on and check the charging status.
Do not open a laptop with a built-in battery just to perform this step. Use the official procedure for your exact model.
10. Consider Battery Replacement or Professional Repair
If none of the previous methods works, the battery, charger, charging port, or internal charging circuit may require repair.
Consider professional service if:
- The battery percentage never increases with a known-compatible charger.
- The laptop shuts down immediately when unplugged.
- The charging port is damaged.
- The battery report indicates significant wear.
- The laptop does not detect its battery.
- The charging indicator repeatedly switches on and off.
Safety warning: If the battery is swollen, leaking, unusually hot, or producing an unusual smell, stop using the laptop and disconnect power if it is safe to do so. Do not press, puncture, or attempt to remove a swollen battery yourself. Arrange professional service.
