Fixing the “No Battery Detected” Error: 4 Ways to Troubleshoot the Laptop Charging Circuit
Sometimes your laptop battery cannot connect with the system, so if you’re receiving any type of message that says No Battery Detected message, it can be irritating and frustrating, especially when it’s urgent, and you want your system to work properly.
This error usually occurs when the laptop cannot connect to or communicate with the battery or when the charging system has problems. But the good thing is that in many cases, the problem can be fixed with troubleshooting steps before considering a battery replacement or repair.

What Does “No Battery Detected” Mean?
When the battery issue is detected, the laptop could be among the devices that are facing the problem due to incorrect system setup, fragmentation, etc. In that case, the laptop needs to be debugged and reset to the factory defaults using a secured USB with no data on it.
After the device has been reset, it has to be reconfigured and updated to the latest version. The overall problem may lead to the laptop battery not being detected, but it can be ruled out by using different methods. It is essential to know the correct ways to interact with the hardware and software features of the device.
To do a power reset properly with a removable battery:
- You could also choose to remove and power reset the battery.
- Power the laptop completely down for some time.
- Unplug the charger from the laptop and disconnect it. Take the laptop battery from its secure slot.
- Now, press and hold the power button for 15-20 seconds to drain any residual power in it. Attach the battery back into its slot and plug in the charger first.
- Power your laptop and check the battery.
- Press and hold the power button for 15–20 seconds.
- Reconnect the charger and turn the laptop on.
Why it works:
Static charge can interrupt the battery’s communication with the motherboard. A power reset clears this and restores normal functioning.
2. Check the Battery Drivers and Update BIOS
Sometimes, your laptop may not detect the battery due to software issues such as outdated drivers or corrupted BIOS settings. Updating or reinstalling these can often fix the error.
- Reinstall the Battery Drivers
The driver used by Windows laptops for conversation with the battery is the Microsoft ACPI-Compliant Control Method Battery driver.
Steps to reinstall the battery driver:
- Right-click on Start and select Device Manager.
- Click to Expand Batteries.
- Right-click on:
Microsoft AC Adapter
- Microsoft ACPI-Compliant Control Method Battery
- Select Uninstall device.
After that, your computer needs to be restarted, which allows Windows to reinstall the drivers automatically on reboot.
How it worked: The corrupted battery drivers might cause the system to misread or to fail to detect the battery. The reinstallation of drivers makes the communication bridge.
B. Update the BIOS
The BIOS manages hardware-level operations, including battery detection and charging behaviour. A bug in the BIOS can trigger battery recognition errors.
How to update BIOS safely:
- Visit your laptop manufacturer’s official support page.
- Search for your model using the serial number.
- Download the latest BIOS update.
- Plug in your charger (BIOS updates require continuous power).
- Run the BIOS update tool and follow the instructions.
Important:
Never interrupt a BIOS update. It can permanently damage your motherboard.
If your HP laptop won’t turn on and you suspect the issue may lie deeper than the battery—such as with the motherboard or power circuitry—our detailed guide can help.

3. Inspect the Charger, Charging Port, and Battery Connection
If your laptop's charging wire has any faults or connection issues, your system may fail to detect your laptop battery.
A. Test the Charger (AC Adapter).
If your charger adapter is damaged or a weak adapter might power the laptop but fail to charge or detect the battery.
Test checklist:
- Does the charger light turn on?
- Is the cable cut, bent, or burnt?
- Does it heat excessively?
- Have you tried using another compatible charger?
If your laptop detects the battery with a different charger, your adapter needs replacement.
B. Check the Charging Port.
Dirt, dust, or physical damage can become the main reason for improper power flow.
What to look for:
- Loose connection when plugging in the charger.
- Dust inside the port.
- Don’t use bent or broken pins.
- Charging port wobbling or shaking.
If the port feels loose, the motherboard’s DC-jack may need repair or replacement.
C. Inspect the Battery Connection.
For removable batteries:
- Check that the battery is seated properly.
- Check for bent or corroded connectors.
- Clean the connectors gently with a dry cloth.
This step requires opening the laptop.
Warning: If you’re not comfortable opening your laptop, ask a technician.
Inside, ensure:
- The battery cable is securely connected to the motherboard
- No burnt or damaged components
- No liquid damage
A loose internal connector often causes intermittent detection issues.
4. Evaluate the Battery Health and Charging Circuit (Hardware Diagnosis).
If the above steps don’t work, the issue may lie deeper in the battery or the motherboard’s charging IC (Integrated Circuit).
A. Test the Battery Health.
Different brands offer dedicated battery health tools:
- Dell: SupportAssist
- HP: HP Hardware Diagnostics
- Lenovo: Vantage or Lenovo Diagnostics
- Asus/Acer: MyAsus, Acer Care Centre
These tools can show:
- Battery capacity percentage
- Charging cycles
- Battery temperature
- Faults or errors
If the tool says “Battery Not Installed” or “Battery Error,” replacement may be required, so we highly recommend that if you receive this type of message, replace your system battery.
B. Charging Circuit Failure (Motherboard Issue).
Inside every laptop is a charging IC that manages:
- Battery charging
- Power distribution
- Voltage regulation
If the charging IC is damaged, your laptop may run on AC power but fail to detect or charge the battery.
Signs of charging circuit failure:
- The battery works in another laptop (rare but possible)
- Battery percentage stuck at 0%
- Overheating near the charging port
- Battery not charging, but “plugged in” appears
Solution:
Charging circuit repair requires:
- BGA soldering station
- Micro-soldering skills
- IC replacement tools
A professional technician should handle this.
When Should You Replace the Battery?
Change the battery if:
- It is swollen or bulging
- Your laptop health tool marks it “Critical”
- The battery is older than 3-4 years
- It is not recognised across multiple devices
- It charges for a few seconds and then stops
Using a swollen battery is dangerous; change it immediately.

Conclusion
It's quite possible that the "No Battery Detected" notification doesn't necessarily suggest your battery is broken. Most often, performing something easy, for instance, restoring power, driver reinstallation, BIOS update, or connector cleaning can rapidly fix the matter.
Notwithstanding, if the matter is with the hardware only, for example, a broken charging port, a dysfunctional adapter, or a dying battery, in such cases, you may require replacing or having it repaired at the motherboard level.
The four troubleshooting tips mentioned above would certainly help you to find out the actual technical challenges and subsequently take the appropriate measures to make your laptop function properly again.
If there is any type of message you’re receiving in your laptop system that shows a No Battery Detected message, it can be irritating and frustrating, especially when it’s urgent, and you want your system to work properly. This error usually occurs when the laptop cannot connect to or communicate with the battery or when the charging system has problems. But the good thing is that in many cases, the problem can be fixed with troubleshooting steps before considering a battery replacement or repair.
