How to Detect a Faulty ASUS Laptop Battery and What to Do

Asus laptop batteries can degrade over time, leading to performance issues and unexpected shutdowns. Here are several signs and steps to help you identify a faulty battery and what actions to take.

Signs of a Bad ASUS Battery

Rapid Discharge: If your laptop battery drains significantly faster than it used to, this could indicate battery wear. Inability to Charge: If the battery does not charge altogether or only charges to a certain percentage, it may be failing. Overheating: Excessive heat during charging or use can be a serious sign of battery issues. Swelling: Physical deformation such as swelling or bulging of the battery is a serious indication of failure and requires immediate attention. Error Messages: Some laptops show battery health warnings in the operating system.

Diagnostic Checks to Identify a Faulty Battery

Battery Health Check in Windows

Follow the steps below to obtain a detailed battery health report:

Open Command Prompt and type the following command: bash powercfg /batteryreport This command generates a battery report saved in a specified directory, which provides detailed information about the battery's health and capacity.

Check Battery Status

In Windows, click on the battery icon in the taskbar to view the estimated remaining time. If it fluctuates wildly or shows inaccurate estimates, the battery may be failing.

Use ASUS Software

Some ASUS laptops come with pre-installed software like MyASUS or ASUS Battery Health Charging. These tools can monitor battery health and provide diagnostics.

Testing and Action Steps

Remove the Battery if Possible

If your laptop has a removable battery, take it out and check for any visible damage. You can also try using the laptop with just the power adapter to see if it functions normally.

Replace the Battery

If you suspect the battery is bad, consider replacing it with a new one to resolve performance issues.

When to Seek Professional Help

If you observe several of these signs or conduct these checks and still have concerns, it may be best to consult with ASUS support or a professional technician. This is especially important if the laptop is under warranty, as contacting ASUS support for assistance is recommended.
