Battery not supplying power/charging

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.

Battery not charging to full

If you experience the problem which is The battery doesn’t be charged when power level is above 95% with AC adapter connected.

This is a normal condition for battery protection, not a problem for either the battery itself or the charging function.

When the battery is charged to 100%, it will stop being charged.  At this time, the battery will self-discharge very slowly owing to the chemical characteristics of a Li-on battery even though the device doesn’t consume any battery power.

The current design of ASUS devices come with built-in RSOC (Relative State Of Charge) and the purpose is to prolong the overall lifespan of the battery. The description below can explain this phenomenon:

  • When the battery capacity is lower 95% with AC adapter connected, the battery will be charged to 100%, then stop being charged.
  • When the battery capacity drops from 100% to 99%~95% with AC adapter connected, the battery will not be charged until the power level drops lower than 95%.
  • When the battery capacity remains around 94% to 97%, the battery will not charge with the AC adapter connected. You can unplug and re-connect the AC adapter several times to resume charging to 100%.

 

If you experience the problem which is The battery stop being charged after the battery level is charged to 60% or 80%.

Please make sure whether you set up Battery Care Mode in MyASUS (for some models, the Battery Health Charging is a separate app). In order to protect the battery, Battery Health Charging allows you to set your battery's maximum power of ROSC (Relative State Of Charge) which helps extend the battery's lifespan. Here you can learn more about MyASUS Device Settings - Introduction.

Note: For Intel Alderlake or AMD Rembrandt CPU models and earlier, this is referred to as Battery Health Charging in MyASUS (some models may use a separate software program). Here you can learn more about the introduction of ASUS Battery Health Charging.

  • Full capacity mode: The battery can be charged to 100%.
  • Balance mode: The battery can be charged to 80%.
  • Maximum lifespan mode: The battery only allows being charged to 60%.
