Few things are more frustrating than plugging in your laptop and seeing that the battery is not charging. Whether your laptop says “plugged in, not charging”, “battery not detected”, or the battery percentage stays at 0%, the problem does not always mean your laptop is broken.
In many cases, laptop battery charging problems are caused by the charger, battery settings, Windows drivers, BIOS, or a worn-out battery. This guide explains 7 practical fixes you can try before replacing your laptop.
Why Is My Laptop Battery Not Charging?
A laptop battery may stop charging for several reasons. The most common causes include:
- Faulty AC adapter or charger
- Loose or damaged charging cable
- Damaged charging port
- Battery protection settings
- Outdated or corrupted battery drivers
- BIOS or firmware issues
- Overheating protection
- Old or worn-out battery cells
Before buying a new laptop battery, it is important to check both the charger and the laptop settings.
Fix #1: Check the Power Adapter and Charging Cable
The first thing to check is the laptop charger. A faulty charger or loose cable can make it look like the battery is not charging, even if the battery itself is still good.
What to Check
- Make sure the AC adapter is firmly connected to the laptop.
- Check if the adapter LED light is on, if your charger has one.
- Inspect the cable for cuts, bends, or exposed wires.
- Try a different wall outlet.
- Remove power bars or extension cords temporarily.
- Check if the charging connector feels loose.
If the laptop only charges when the cable is moved to a certain angle, the adapter connector or laptop charging port may be damaged.

Fix #2: Restart the Laptop and Perform a Hard Reset
Sometimes the laptop power system can freeze or fail to detect the battery correctly. A hard reset can clear temporary power-management issues.
For Laptops with Removable Batteries
- Shut down the laptop completely.
- Unplug the AC adapter.
- Remove the battery.
- Hold the power button for 30 seconds.
- Reinstall the battery.
- Reconnect the charger.
- Turn on the laptop.
For Laptops with Internal Batteries
- Shut down the laptop.
- Unplug the charger.
- Hold the power button for 30 seconds.
- Reconnect the charger.
- Turn on the laptop.
This simple reset can often fix a “plugged in, not charging” message.
Fix #3: Check Battery Health in Windows
Laptop batteries wear out over time. A battery may still be detected by the laptop but no longer hold enough charge for normal use.
In Windows, you can create a battery report to check the condition of your battery.
How to Generate a Battery Report
- Right-click the Start button.
- Select Terminal (Admin) or Command Prompt (Admin).
- Type the following command:
powercfg /batteryreportWindows will create a battery report showing important information such as:
- Design Capacity
- Full Charge Capacity
- Cycle Count
- Battery usage history
If the Full Charge Capacity is much lower than the Design Capacity, the battery is likely worn out.
Signs Your Battery May Need Replacement
- The laptop shuts down suddenly.
- The battery percentage jumps up or down quickly.
- The battery does not charge past a certain percentage.
- The runtime is much shorter than before.
- The battery is swollen.
- The laptop says the battery is not detected.

Fix #4: Reinstall Battery Drivers
Windows battery drivers can sometimes become corrupted. Reinstalling them may fix charging detection problems.
Steps to Reinstall Battery Drivers
- Press Windows + X.
- Open Device Manager.
- Expand Batteries.
- Right-click Microsoft AC Adapter and select Uninstall device.
- Right-click Microsoft ACPI-Compliant Control Method Battery and select Uninstall device.
- Restart the laptop.
Windows will automatically reinstall the battery drivers after restarting.
Fix #5: Update BIOS and Firmware
The BIOS controls important hardware functions, including battery charging and power management. If the BIOS is outdated, the laptop may not communicate with the battery correctly.
Check your laptop manufacturer’s support website for BIOS or firmware updates. Common brands include:
- HP
- Dell
- Lenovo
- ASUS
- Acer
- MSI
- Samsung
If the charging issue started after a Windows update, a BIOS update may help restore proper battery charging behavior.
Fix #6: Check Battery Charging Limit Settings
Many modern laptops have battery protection features that stop charging at 60%, 70%, or 80%. This is designed to extend battery lifespan.
Examples include:
- Lenovo: Conservation Mode
- ASUS: Battery Health Charging
- Dell: Dell Power Manager
- HP: Adaptive Battery Optimizer
- Acer: Battery Charge Limit
- MSI: Battery Master
If your battery stops charging at around 60% to 80%, check the manufacturer’s battery management software. Your battery may not be defective.
Fix #7: Replace the Laptop Battery
If none of the above fixes work, the battery may be worn out and need replacement.
Battery replacement is usually much more affordable than replacing the whole laptop. Before ordering a replacement battery, always confirm the correct battery model.
What to Check Before Buying a Replacement Battery
- Original battery model number / OPN
- Laptop model number
- Battery voltage
- Battery shape
- Connector location
- Capacity and cell type
Some laptop batteries have similar laptop model compatibility but different shapes or connectors. Checking the original battery label is the safest way to confirm compatibility.
Common Compatible Voltage Examples
- 10.8V and 11.1V are commonly compatible.
- 14.4V and 14.8V are commonly compatible.
- 11.25V and 11.55V are commonly compatible.

Frequently Asked Questions
Why does my laptop say plugged in not charging?
This can be caused by battery protection settings, a faulty charger, outdated battery drivers, BIOS issues, or a worn-out battery.
Can a laptop battery suddenly stop charging?
Yes. Laptop battery cells can fail unexpectedly, especially after several years of use or exposure to heat.
How do I know if my battery or charger is bad?
If the laptop works when plugged in but shuts down immediately when unplugged, the battery may be bad. If the laptop does not power on or loses power while plugged in, the charger may be faulty.
Is it safe to use a laptop while charging?
Yes. Modern laptops are designed to be used while charging. However, excessive heat can reduce battery lifespan.
Should I replace the battery or buy a new laptop?
If the laptop still works well, replacing the battery is usually much more affordable than buying a new laptop.
Final Thoughts
A laptop battery that is not charging does not always mean the battery is dead. Start with simple checks such as the charger, cable, power reset, battery drivers, and charging limit settings.
If the battery is old, swollen, not detected, or has very low full charge capacity, replacing the battery may be the best solution.
