Although it is nothing new to buy a laptop now, many users still have many misunderstandings in the use of the notebook. For example: Do you want to remove the battery when the laptop is connected to an external power supply? Can you use the notebook while on the move? These problems are often encountered in our daily use of laptops, but not everyone is using them correctly. Many people choose to take off the laptop battery for the purpose of "protecting the battery" when the laptop is connected to external power. They often hear these rumors - "the laptop battery has only a few hundred charge and discharge life", when the external power supply Not removing the battery is equivalent to charging the battery, shortening the battery life. Although the lithium-ion battery used in most laptops now has self-discharge, it is a slow process: if a laptop's lithium-ion battery is 100% fully charged, it takes about two weeks to a month. Will be reduced to 90% or 95% of the original power. The power control circuit of many laptops is automatically charged when the battery reaches 90% or 95%. That is to say, putting the battery in the notebook and then plugging in the AC power does not charge once every time it is turned on, but instead After two weeks to one month, the battery will be automatically charged once the battery is below 90% or 95%. If you still feel that charging the battery too often for two weeks to one month, I can't say anything. I just want to remind you that the sudden power outage is far more than the laptop battery consumption for laptops and laptop users: if you are writing a thesis, the hostel suddenly loses power and you don’t save the paper in time, then you will regret it. Put a battery on your notebook. Sudden power outages often occur in areas with unstable power supplies or in the summer when power is used. Sudden power outages are not only harmful to your notebook, but irreparable data is regrettable. In addition, the battery of the notebook computer is removed, and the battery compartment is exposed, so that it is easy to enter a large amount of dust and cause poor contact when the battery is used.
