If the laptop charger has been plugged into the computer. How many times has it been charged?

If your laptop battery is connected to the laptop charger because it is out of power, the battery will be charged first. If you continue to connect the power supply after the battery is fully charged, the battery will not be charged. At this time, the notebook uses power from the power source.

If you are not at ease, you can set it through the battery power management. Set it to start charging when the battery is below the amount of power, which will reduce the number of times your battery is charged. For example, if the battery you set is charged at less than 30%, then your battery will not be charged if it has 40% electricity. That is also a protection for the battery. Because frequent charging and discharging will affect the life of the battery. Of course, it is not good if the battery is not used for a long time. The battery must be charged and discharged at least once a week. The battery will be damaged if the battery is not used for a long time.
