Check battery/AC adapter connection and appearance
  1. Use the original ASUS adapter to avoid compatibility issues. If you have different ASUS products, do not mix adapters as power output specifications may differ.
  2. Check the adapter jack for any looseness at the power cord plug (A), outlet side plug (B), or device side (C). Consider trying different outlets. (The following illustrations use a laptop as an example. For detailed information, please refer to the User Manual for your specific device model.)   
  3. Inspect the adapter and cables for any signs of damage. If damaged, it is recommended to visit an ASUS service center for a replacement.
  4. After confirming the above, try reconnecting the power cable/plug/device ends.
  5. If your laptop has a removable battery, try reassembling it. Skip this step if the battery is non-removable.   
  6. If the device/battery has not been charged for a while, connect it to power and leave it charging overnight. This may help revive the battery.
  7. If the issue persists after the above checks, proceed to the next troubleshooting step.

Check the battery charging time in Safe Mode

Some applications in Windows consume more battery power than others, so it might cause the slow charging. Please try to measure the battery charging time in Safe Mode and compare it with the normal charging time when operating in Windows operating system. Here you can learn more about How to enter Safe Mode.

If the difference in time is significant, it means there may be some applications or background programs that could have faster battery power consumption in Windows. If you do not know which applications are the cause, please try to reset your device. Here you can learn more about How to reset the system.

Note: Please backup your personal files, then reset the device.
