    Why your laptop can't detect the battery or display the battery level properly after installing the battery? It may be caused by a loose battery. Please check if the battery cable is installed correctly. It may be due to the damage of the conductive material caused by the laptop motherboard and the battery positive contact position, you can try to use the original battery to confirm. Check if the battery driver is normal, if not, please download the appropriate driver software to update.
