Does the laptop need to be plugged in all the time?

Laptops do not need to be plugged in all the time. If the laptop is almost out of power while using it, you need to plug it in in time. However, the laptop can always be plugged in when not in use.

If you occasionally forget to unplug the power supply, the computer will not be damaged. Of course, it is recommended to remember to unplug the power cord when the laptop is not in use. The laptop battery is equipped with a chip and will be automatically controlled, so it doesn't matter if the laptop power adapter is always plugged in.

In the off state, if it is charging, the charging indicator light will generally appear orange or flash. After it is fully charged, it turns green and stays on, and the control chip automatically disconnects the charging circuit. Even if it is always plugged in, you don’t have to worry about bursting your battery. Unplugging it has at least two benefits: ① It makes the adapter power off and stop working. rest. ②Prevent accidental power surges from damaging the adapter.

Notes on the use of laptop batteries:

Careful laptop users like to take off the battery from the machine when the battery is not in use. This can This prevents repeated charging of the battery from affecting battery life and also reduces the weight of the notebook. It is recommended not to save any more. For the sake of data security, it is best to put the battery back into the laptop, otherwise the data will be "mercilessly" lost if you are not careful. In fact, this approach is not worth the gain.

There are not so many problems when installing batteries on machines. The batteries use lithium-ion cells, and the memory effect of the battery is very small. In addition, most batteries have smart chips inside. This small chip can not only control the battery The charging capacity also detects whether the battery needs charging. Generally, charging will only start when the battery capacity is lower than 90% to 95%, so the battery will not always be charged when it is placed on the laptop.

Ideally, you should try to keep your battery charge between 20% and 80%. Remember, these are the best ways to unplug your machine until the battery reaches 100%. Also, don’t wait until the battery is dead before charging it. Try to keep your laptop cool. Turning off the computer and charging it is the best way to charge it.

When you turn on your laptop, you should pull the battery out of your computer and then plug it back in. Although this method is inconvenient, using it plugged in when the battery is fully charged will cause great damage to your battery. After years of research and development, the problem of battery overcharging has been basically solved. Unlike early nickel-metal hydride batteries, if the commonly used lithium batteries often completely discharge the stored power, the battery life will be greatly shortened, which manifests as The only thing is that the capacity of the battery pack has dropped significantly.

So some friends will ask how much power is appropriate for the battery to retain? According to many people's experience, the remaining power of the battery pack should not be less than 5% of the total power. There are two major laptop brands, IBM and Sony, that can view battery information relatively completely (including total design capacity, actual total capacity, number of charges, manufacturer, health level, etc.), while other brands can only rely on third-party software.

Some friends may not move their notebook much, and the battery will be idle at home for many years. They may fully charge the battery and then put it aside. In fact, this is wrong, as the cells in the battery pack will age mercilessly. The battery should not be fully charged, it only needs to be charged to about 40% to 65% of the total capacity. Remove the charged battery, wrap it in plastic wrap and store it properly in a ventilated, cool place out of direct sunlight.
