ASUS VivoBook 15 X1504: Battery Not Charging Fix
Intel Core i5-1235U • Windows 11 • Budget Laptop
The ASUS VivoBook 15 X1504 with Intel Core i5-1235U uses a standard 65W barrel-connector charger. When the battery stops charging — the system runs on AC power but the battery percentage stays flat or shows Not charging — ASUS Battery Health Charging mode or a driver issue is almost always the cause.
Disable Battery Health Charging
Open MyASUS app > Battery Health Charging. If set to Balanced (80% cap) or Maximum Lifespan (60% cap), the battery will not charge beyond those limits. Switch to Full Capacity Mode to allow charging to 100%. This is the most common cause of the battery appearing stuck.
Reinstall Battery Driver
Open Device Manager > Batteries. Right-click Microsoft ACPI-Compliant Control Method Battery and select Uninstall device. Restart. Windows reinstalls the driver automatically on boot, which resets the battery charge controller communication and resolves stuck charging states.
Power Cycle Without Battery
Shut down fully. Disconnect the charger. Hold the power button for 30 seconds to discharge capacitors. Reconnect only the charger (no battery if removable). Power on and check if the AC adapter is recognized. Then shut down, reconnect the battery, and power on to recheck charging status.
Test with a Different Charger
The VivoBook 15 X1504 requires a 65W barrel-pin adapter. A faulty or counterfeit charger may supply power to run the laptop but deliver insufficient wattage to charge the battery simultaneously under load. Test with an original ASUS 65W adapter. A 45W charger may run the laptop but not charge during high CPU activity.
Update BIOS
Visit ASUS Support, search for the VivoBook 15 X1504, and install the latest BIOS. BIOS updates include EC firmware fixes that address battery charge controller behavior. Some VivoBook battery charging bugs are BIOS-level issues that cannot be fixed by Windows driver reinstalls alone.
Run Windows Battery Report
Open Command Prompt as administrator and run powercfg /batteryreport. Open the generated HTML report and check Design Capacity vs Full Charge Capacity. If Full Charge Capacity is less than 50% of Design Capacity, the battery has degraded and requires replacement regardless of driver or software fixes.

Why is the ASUS VivoBook 15 X1504 battery not charging?
The most common cause is the ASUS Battery Health Charging feature set to Balanced (80% limit) or Maximum Lifespan (60% limit) in the MyASUS app. These modes intentionally prevent charging above the set threshold to prolong battery life. Open MyASUS and switch to Full Capacity Mode to allow charging to 100%.
How long does the ASUS VivoBook 15 X1504 battery last?
The ASUS VivoBook 15 X1504 includes a 42Wh battery. Real-world battery life is approximately 5-7 hours for light productivity tasks at medium brightness with the Intel Core i5-1235U. For longer battery life, enable Battery Saver mode in Windows Settings and reduce display brightness to 50% or below.
What charger does the ASUS VivoBook 15 X1504 use?
The ASUS VivoBook 15 X1504 uses a 65W barrel-pin AC adapter (4.5mm x 3.0mm connector). It does not support USB-C charging. Always use the original ASUS 65W adapter or a compatible third-party 65W adapter with the correct barrel connector size to ensure proper charging voltage and wattage delivery.
Can I use a higher wattage charger on the ASUS VivoBook 15 X1504?
Yes. A higher wattage adapter with the same barrel connector (65W or 90W) can safely charge the VivoBook 15 X1504. The laptop draws only what it needs — a 90W adapter will not overcharge the battery. However, a lower wattage adapter (45W) may not charge the battery while the CPU is under load.
