Many people in the use of laptop computers, most of them are charging while using, I believe that careful people will find that after the computer is fully charged, the charging indicator has been on, is the power adapter has been working? Today with the flying eagle to find out.
Computer without power will become very card, but after connecting the power adapter, it will work normally, play games and so on, not at all card, is because the laptop is connected to the adapter, it will prioritize the use of external power, the remaining power will be stored in the battery, if the power adapter is no longer connected to the power supply, the laptop will only use the power inside the battery. If the battery is full, the laptop starts the battery saver program, the battery no longer accepts external power and stops working, which is when the laptop uses the power adapter to provide external power.
Although the adapter has been working, but if you use a genuine product, there are over-current, over-voltage, short-circuit, reverse current, under-voltage, over-temperature, overload, static electricity and other protective measures, the charger will always be low-power working condition, will not have an impact on the life of the battery.
