ASUS VivoBook S 16 AMD Ryzen 7 7730U Battery Not Charging Fix Windows 11

The battery on your ASUS VivoBook S 16 AMD Ryzen 7 7730U stops charging at 60 or 80 percent while plugged in, or the battery shows plugged in but not charging immediately after connection. ASUS Battery Health Charging or USB-C adapter wattage issues are the most common causes of the battery not reaching full charge.

This guide covers ASUS Battery Health Charging settings, adapter compatibility, and battery driver reinstallation to restore full battery charging on the ASUS VivoBook S 16 in Windows 11.

“VivoBook S 16 battery stopped at 80 percent every time. Found ASUS MyASUS had Battery Health Charging at 80 percent limit. Switched to Full Capacity for long trip and battery charged to 100 percent.” – Wan Faridah, teacher from Ipoh

Why Battery Does Not Charge Past 80 Percent on ASUS VivoBook S 16

ASUS MyASUS includes a Battery Health Charging feature that intentionally limits maximum charge to either 60 or 80 percent to reduce lithium battery degradation from keeping the battery at 100 percent while plugged in continuously. This feature is excellent for battery longevity in office use but appears as a charging fault to users who are not aware it is active. The battery stops charging at the set limit and displays Plugged in, not charging in Windows taskbar.

• ASUS Battery Health Charging set to 60 or 80 percent limit via MyASUS application
• USB-C charging adapter below minimum wattage causing system to run on adapter power without charging battery
• ACPI Battery driver error after Windows update preventing battery state reporting
• Battery connection loose or charging port debris preventing full charger contact

Fix 1 – Check ASUS Battery Health Charging in MyASUS

Open ASUS MyASUS application. Navigate to Customization – Battery Health Charging. Check the current setting: Full Capacity Mode allows charging to 100 percent, Balanced Mode limits to 80 percent, Maximum Lifespan Mode limits to 60 percent. For travel or extended use away from power, select Full Capacity Mode. For daily office use while always plugged in, 80 percent is recommended for battery longevity. Change the setting and the battery immediately resumes charging towards the new limit.

Fix 2 – Verify AC Adapter Wattage

Check the original ASUS adapter wattage for the VivoBook S 16 – typically 65W for AMD Ryzen 7 configurations. If using a third-party USB-C adapter, verify it supports USB Power Delivery at 65W or higher. An adapter below the minimum wattage provides enough power to run the system but not enough excess to charge the battery under load. The taskbar shows Plugged in, not charging because the adapter draws equal to system load with no surplus for battery charging current.

Reinstall ACPI Battery Driver

Open Device Manager. Expand Batteries. Right-click Microsoft ACPI Compliant Control Method Battery and select Uninstall device. Disconnect the AC adapter. Wait 30 seconds. Reconnect AC adapter. Windows automatically reinstalls the ACPI battery driver on reconnection. A corrupted ACPI battery driver can report incorrect charge states, causing charging to appear to stop at a percentage threshold even when the hardware is charging normally.

Fix 3 – Update ASUS MyASUS and BIOS

Open Microsoft Store and update ASUS MyASUS to the latest version. Also open MyASUS – Customer Support – Live Update or check ASUS Support for BIOS updates for the VivoBook S 16 AMD. BIOS updates for the VivoBook S 16 sometimes include battery management firmware fixes that correct charging current control, particularly for USB-C PD charging profiles and Battery Health Charging mode transitions.

Fix 4 – Clean Charging Port Contacts

If the VivoBook S 16 uses a barrel connector (not USB-C) for the primary charger, inspect the port for debris with a flashlight. Use a dry toothpick to gently clear any lint from the barrel connector port. A partially obstructed charging port can cause intermittent charging contact that presents as plugged in but not charging in Windows. Ensure the charger plug clicks or seats firmly without the cable being held at an angle to maintain contact.
