First of all, to answer the question, the laptop has been charging no damage to the computer, it is best to plug in when using.

In terms of battery, the energy supply of notebooks and mobile phones is different, and there are three situations:
The battery is not satisfied with the plug-in use: at this time, part of the power is supplied to the battery charging, part of the supply is used;
The battery is fully charged and plugged in: at this time, the power is only supplied for use, not through the battery, which is why the battery can still be used normally;
Unplugged: Battery powered.
So from the battery side, the best way is to use the battery fully plugged in, at this time without the battery, there is no battery loss, and from the principle of lithium batteries, floating charging is more life-saving than deep discharge, that is to say, no power is charged, do not use up again.

Moreover, in terms of performance, the notebook power limit is not the same when plugged in and using the battery, the CPU can be maintained at TDP when plugged in, the graphics card can hit the power wall to ensure maximum performance, and the battery is often not able to supply enough power when using the battery, resulting in CPU and graphics card frequency reduction, which is obvious when playing the game in the game.

To sum up, it is best to plug in the notebook when using, thank you.

Explain something about overcharging
At present, almost all the laptops used are lithium batteries (Li-Ion).
Lithium battery charging is divided into three states, trickle charging, constant current charging, constant voltage charging. We are concerned about the last state, when the battery voltage reaches the nominal value, the charging current slowly decreases from the maximum value as the charging process continues, and when it is reduced to 0.01C, it is considered that the charging terminates. This process is controlled by a circuit or software. (C is a representation of the nominal capacity of the battery against the current, such as the battery is 1000mAh capacity, 1C is the charging current 1000mA.)
Make it clear that long charging time and overcharging are not the same thing. Overcharge refers to charging when the voltage is higher than the charging cut-off voltage, generally 4.2V lithium batteries. The voltage level determines whether the battery is overcharged, and has nothing to do with how long it is charged. Generally due to the charger or battery management chip, the highest output voltage to the positive and negative ends of the battery is 4.2V. Even if you do, there's a protective plate built into the lithium battery. This means that the voltage to the cell will never exceed 4.2V, and it will not be overcharged for a long time.
\"Charging for a long time will not overcharge\" this sentence may not be consistent with most common sense, but in fact, the danger of using lithium batteries, or explicitly \"explosion\" it, there are three reasons, one is the control circuit or software related setting errors, will make the battery compounds appear unstable, there is a researchers call \"thermal runaway\" problem. This could cause a burning or explosion. Second, the lithium battery temperature is too high, it will also cause an explosion. Third, there is a problem with the isolation material of the anode and cathode in the lithium battery, leading to overheating or explosion, that is, the process error said in the Samsung note7 explosion will make the anode and cathode contact leading to the lithium battery explosion.
Therefore, in use, in order to avoid risks, one is to use batteries produced by regular manufacturers, the second is to prevent batteries from overheating or overheating risk, the third is to do more good deeds, good character is the most important (manual dog head).
