Asus Laptop Not Charging – The Most Common Fixes

Laptop batteries don’t last forever, and your Asus is no different. As is the case with most lithium-ion batteries, these devices offer diminishing charging capabilities over time. Not only can this limit your unplugged time, but it may even reduce the maximum charge you can achieve.

Let’s look at some of the common causes, how to troubleshoot them, and solutions you can implement on your Asus laptop at home.

Asus Laptop Not Charging When Plugged In

Occasionally, users may notice that their laptop isn’t charging even though it’s plugged in. It’s one of the most annoying instances of a malfunctioning charging process, and it can happen for many reasons. Check out the troubleshooting tips below to pinpoint the issue:

Reinserting the Battery

One of the fastest ways to troubleshoot a malfunctioning charging process is removing and putting back the battery in your laptop.

1. Power off your device.
   
2. Remove the battery.
   
3. Check if the laptop can boot while plugged in.
   
4. Shut down the laptop again.
   
5. Add the battery.
   
6. Plug the AC adapter to see if it works.
   

If this doesn’t change anything, you can move on to other possible solutions.

Bad Battery Driver

Like most hardware components found inside laptops, batteries also have drivers. A corrupted, missing, or outdated driver could prevent your battery from charging.

Here’s how to check the battery driver status and make the necessary tweaks:

1. Open the WinX menu by pressing the Windows Key and X on your keyboard.
   
2. Click on the “Device Manager” option.
   
3. Go to the Batteries tab from your Device Manager window.
   
4. Right-click on the “Microsoft ACPI-Compliant Control Method Battery.”
   
5. Select the “Uninstall Device” action from the context menu.
   
6. Confirm the selection by clicking the “Uninstall” button.
   
7. Click the “Action” button.
   
8. Select the “Scan for Hardware Changes” option.
   
9. Select the Batteries tab.
   
10. Right-click the “Microsoft ACPI-Compliant Control Method Battery” option.
    
11. Choose the “Update Driver Software” option.
    
12. Look for the driver automatically.

If you don’t see the “Microsoft ACPI-Compliant Control Method Battery” option, you might need to uninstall the battery driver. This, too, may indicate a driver issue when your laptop isn’t charging.

BIOS Problems

The BIOS is like your laptop’s brain and controls everything related to the motherboard and other hardware components. Should a driver update not fix the charging issue, you could be looking at a BIOS problem.

Check if your laptop works while plugged-in without its battery. If it does, you can try to update your BIOS.

1. Go to Asus’s main website.
   
2. Look for your laptop’s model.
   
3. Access the BIOS and Firmware category.
   
4. Download the latest BIOS Installer.
   
5. Extract the contents of the downloaded file archive.
   
6. Double click on the BIOS Installer application icon.
7. Follow the Setup Wizard to begin the update process.
8. Allow the laptop to restart to complete the update.

Alternatively, you can use WinFlash to accomplish the same thing.

1. Download the application from the Asus Support site, located in the BIOS and Utilities Category.
   
2. Extract the downloaded file to the desired folder.
   
3. Double click the Setup executable.
   
4. Follow the instructions in the Setup Wizard.
   
5. After the installation is completed, type “WinFlash” in the search bar.
   
6. Click it to open the application.
   
7. Choose the “preferred” option to get the BIOS update file.
8. Click the “Update” button.
   
9. Exit the WinFlash application.

Your laptop will reboot automatically and proceed with the update procedure.

Battery Check Software

These days you can find various software monitors for your hardware components. Some can even check the wear levels on the battery, temperature, and other operating parameters.

Consider third-party monitoring tools, but check the compatibility with your components before relying on any readings.

Asus Laptop Not Charging & Not Turning On

There are instances when you can use your laptop plugged in, but your battery isn’t getting a charge.

However, if the battery isn’t charging and you can’t turn on your laptop, you’re most likely dealing with a damaged or dead AC adapter.

Try using a different adapter with the same voltage rating and see what happens. If nothing changes, you may need to send your laptop into service.

Alternatively, you might consider cleaning the adapter and charging port. Dust and debris can interfere with the charging process, similar to what happens with smartphones. Using a lint-free fabric should be enough.

Another common problem occurs when using a non-original AC adapter to charge your laptop. Once again, you should check the laptop and battery status with an original adapter, if possible. If it does the trick, the battery is likely dead. If this still doesn’t work, you could be looking at even more severe issues like something fried on the motherboard.

Asus Laptop Not Charging Fully to 100%

Batteries use sensors to give accurate power readings. On occasion, these sensors may lose their calibration due to various reasons such as software and hardware changes, power surges, etc.

In some situations, your battery might be at 100%, but you could get a bad reading.

Before going into other battery fixes, try resetting the battery to ensure that the smart sensor is calibrated correctly and fully interfacing with the laptop. The process doesn’t require special tools or technical skills. Here’s how to get started:

1. Let your battery fully drain.
   
2. Turn over your laptop to access the battery compartment.
   
3. Remove the battery using the special tabs on the casing. Alternatively, remove the screws to take out the battery in older laptop models.
   
4. Boot your laptop while plugged in to see if it works.
   
5. Shut down your laptop after the check.
   
6. Press and hold the power button for 30 seconds.
   
7. Put back the battery and let it charge for an hour.
   
8. Boot your laptop again, let the battery charge to full and recheck the reading.
   
   

If your laptop comes with a non-removable battery, check the owner’s manual for the location of the battery reset button. Most laptops with this design should have a battery reset button.

Check for Overheating

Laptops tend to power off if they overheat and reach a specific temperature threshold as a protective mechanism. This happens to protect certain sensitive components.

Overheating usually happens with CPUs and GPUs, but it can happen with batteries too. If your laptop’s battery is hotter than usual, try removing it and let it cool off for a while.

Once it’s sufficiently cooled, replace the battery, and charge your laptop.

If it’s still not reaching 100% and the battery overheats again, then your battery is almost gone. Consistent charging and age will wear batteries down. In most cases, batteries won’t outlive the laptops they came in so, you could consider a replacement.

Batteries Have Simple Troubleshooting Techniques

Figuring out if you’re dealing with a dead battery shouldn’t take more than an hour if you follow the tips in this article. As a general recommendation, if you’re experiencing charging issues in a three-year-old laptop or an older one, the chances are that no software tweak will restore the battery to peak performance levels.
