ASUS ExpertBook B1402CGA Battery Not Charging

The laptop does not charge properly or loses battery power quickly.

A damaged power adapter may prevent the laptop from charging. Check that the adapter connects securely to the laptop. Inspect the charging cable for visible damage or bent connectors. Test the adapter using a working electrical outlet. Try another compatible ASUS power adapter if available. Replace the adapter if another one charges the laptop successfully.

Certain battery settings may prevent the laptop from charging completely. Open the MyASUS application and locate the battery settings. Check whether Battery Care Mode limits the charging percentage. Some ASUS laptops stop charging at 60% or 80%. Adjust these settings if your model supports them. Check whether the battery charges normally afterward.

Outdated battery drivers may interfere with normal charging operations. Open Device Manager and expand the Batteries section. Locate Microsoft ACPI-Compliant Control Method Battery. Right-click the device and select Uninstall device. Restart the laptop to reinstall the driver automatically. Check whether the charging problem continues.

Laptop batteries gradually lose their ability to hold a charge. A damaged battery may require replacement. Open Command Prompt and enter powercfg /batteryreport. Review the battery report for reduced charging capacity. Replace the battery if testing confirms it is defective. Follow the ASUS ExpertBook B1402CGA Battery Replacement Guide.
