1, Generally speaking, many computer brands such as Dell, Lenovo, SONY, etc., will be equipped with their own laptop power management software, if enabled a \"battery protection mode\
2, therefore, if you find that your notebook does not charge, you can first enter the relevant power management software, turn off the battery protection mode or eliminate the forbidden charging option, if the hardware is not wrong, the battery will be able to charge.
3, the battery's own hardware failure, generally speaking, you can use to restart the computer, re-plug the battery to judge, if the battery is still unable to charge, may wish to remove the battery to clean up the dust of the battery, and then try.
4, you can also install some hardware detection applications to obtain the approximate battery loss reference information. 1. When there is no external power supply, if the card in the PCMCIA slot cannot be used for the time being, it is recommended to remove the card first to extend the battery life. 2, room temperature (22 degrees) is the most suitable operating temperature for the battery, the temperature is too high or too low operating environment will reduce the battery time. 3, when using the laptop in an environment that can provide a stable power supply, remove the battery to extend the battery life. As far as Asus laptops are concerned, when the battery power is fully charged, the charging circuit in the battery will automatically shut down, so there will be no overcharging. 4, it is recommended to carry out an average of three months battery power correction action.
5, minimize the number of battery charge and discharge times of the battery is directly related to the life, each charge, the battery is a step forward to retirement. It is recommended that you use the external power supply as much as possible, 6, the battery should be removed when using the external power supply (lithium battery is not in this column). Some users often plug and unplug the power several times a day, and the laptop is equipped with a battery, so that the damage to the battery is greater. Because each external power supply access is equivalent to charging the battery once, the battery will naturally lifespan (especially nickel-metal hydride and nickel-cadmium batteries, which do not exist in lithium batteries). 7, charge after the battery is exhausted and avoid charging time is too long your notebook is using nickel-metal hydride batteries and nickel-cadmium batteries, be sure to use up the power and then charge (less than 1%), which is the best way to avoid memory effect. 8, usually use precautions: in normal use to prevent exposure, to prevent moisture, to prevent chemical liquid erosion, to avoid the battery contact with metal contact and other situations.
