Laptop batteries don't last forever, and your Asus is no different. As is the case with most lithium-ion batteries, these devices offer decreasing charge capacities over time. Not only can this limit your unplugging time, but it can even reduce the maximum load you can achieve.

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

Asus laptop does not charge when plugged in

Sometimes users may notice that their laptop is not charging even though it is plugged in. This is one of the most annoying cases of a faulty charging process, and it can happen for many reasons. Check the troubleshooting tips below to identify the problem:

Reinserting the battery

One of the quickest ways to troubleshoot a faulty charging process is to remove and reinsert the battery in your laptop.

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

If that 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 A corrupt, missing, or outdated driver can prevent your battery from charging.

Here's how to check the battery driver status and make any necessary changes:

  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 of your Device Manager window.
  4. Right-click "Battery with Microsoft ACPI Compliant Control Method".
  5. Select the "Uninstall device" action from the context menu.
  6. Confirm the selection by clicking the "Uninstall" button.
  7. Click on the “Action” button.
  8. Select the “Scan for hardware changes” option.
  9. Select the Stacks tab.
  10. Right-click on the “Battery with Microsoft ACPI Compliant Control Method” option.
  11. Choose the “Update Driver Software” option.
  12. Search for the driver automatically.

If you don't see the "Battery with Microsoft ACPI Compliant Control Method" option, you may need to uninstall the battery driver. It can also indicate a driver problem when your laptop is not charging.

BIOS issues

The BIOS is like the brain of your laptop and controls everything about the motherboard and other hardware components. If a driver update does not fix the charging issue, you might be facing a BIOS problem.

Check if your laptop works when plugged in without its battery. If so, you can try updating your BIOS.

  1. Go to the main page of Asus website.
  2. Find your laptop model.
  3. Go to the BIOS and Firmware category.
  4. Download the latest BIOS installer.
  5. Extract the contents of the downloaded file archive.
  6. Double-click the BIOS installer application icon.
  7. Follow the setup wizard to begin the update process.
  8. Let the laptop 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 installer executable.
  4. Follow the Setup Wizard instructions.
  5. Once the installation is complete, type “WinFlash” in the search bar.
  6. Click on it to open the application.
  7. Choose the "preferred" option to get the BIOS update file.
  8. Click on the “Update” button.
  9. Quit the WinFlash application.

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

battery check software

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

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

Asus laptop won't charge or turn on

In some cases, you can use your laptop plugged in, but your battery won't charge.

However, if the battery won't charge and you can't turn on your laptop, you're probably dealing with a damaged or dead power adapter.

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

You may also consider cleaning the adapter and the charging port. Dust and debris can interfere with the charging process, as is the case with smartphones. Using a lint-free cloth should suffice.

Another common problem occurs when using a non-original power adapter to charge your laptop. Again, you should check the condition of the laptop and the battery with an original adapter, if possible. If it works, the battery is probably dead. If it still doesn't work, you might be facing even more serious issues, like something fried on the motherboard.

Asus laptop not fully charging to 100%

Batteries use sensors to give accurate power readings. Occasionally, 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 might get a bad reading.

Before moving on to other battery fixes, try performing a battery reset to ensure that the smart sensor is properly calibrated and interfacing with the laptop perfectly. The process does not require any special tools or technical skills. Here's how to start:

  1. Allow your battery to discharge completely.
  2. Turn your laptop over to access the battery compartment.
  3. Remove the battery using the special tabs on the case. You can also remove the screws to remove the battery from older laptop models.
  4. Boot your laptop while plugged in to see if it works.
  5. Turn off your laptop after the check.
  6. Press and hold the power button for 30 seconds.
  7. Replace the battery and let it charge for an hour.
  8. Restart your laptop, let the battery fully charge, and recheck the reading.

If your laptop came 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 shut down if they overheat and reach a specific temperature threshold as a protection mechanism. This happens to protect some sensitive components.

Overheating usually happens with CPUs and GPUs, but it can also happen with batteries. If your laptop battery is warmer than usual, try removing it and allowing it to cool for a while.

Once it's cooled down enough, replace the battery and charge your laptop.

If it still does not reach 100% and the battery overheats again, then your battery is almost drained. Constant charging and age will deplete the batteries. In most cases, batteries won't outlast the laptops they come in, so you might want to consider a replacement.

Batteries have simple troubleshooting techniques

Determining if you're dealing with a dead battery shouldn't take more than an hour if you follow the advice in this article. As a general recommendation, if you're having charging issues in a laptop that's three years old or older, it's likely that no amount of software tweaks will restore the battery to peak performance levels.
