Make sure the power cable and the AC adaptor are properly connected. If you are using a table faucet or an extension cord, plug the power cable directly into the outlet and check if the battery can be charged. If you are using an AC adapter other than the original NEC product or Smartphone charger, you may not be able to charge the battery properly.
If the battery cannot be charged while the PC is receiving power normally, then check the following points:
Check the status of the battery charge indicator on the device. Normally, the orange lamp is on. If the lamp is off, the power is not connected or the battery is fully charged. If the orange light is blinking, the battery has undergone some error, please refer to the information below. Q & What if the battery charge indicator (battery symbol) flashes orange on your laptop?
The battery may not charge due to the poor connexion between the battery pack and the main unit. If the battery pack is removable, then remove it and install it, do it several times to see if the problem persists.
The more often a battery is charged, the more it deteriorates. Use the \"Battery Refresh & Diagnostic Tool\" to refresh the battery and diagnose the problems. For more information on the \"Battery Refresh & Diagnostic Tool\", please refer to the given information and check the version of Windows (OS) you are using.
Q&A \"About the battery diagnostic and refresh tool”
Some models do not have the \"Battery Refresh & Diagnostic Tool\" installed. Please consult the manual attached with your PC.
If the above solutions do not solve the problem, the battery may be dead or there is a problem with the power cord or AC adaptor. If the battery is connected to a power outlet, it can be overloaded and the heat can speed up its deterioration. If the battery has not been used for a long time, it may discharge excessively and fail to recharge. For more information on battery life, please refer to the information below.
