Since I get full power when I have the power on my laptop, should I just remove the battery from the laptop and leave it permanently on the power? And should I then remove the power cable when the laptop is switched off?
I would leave the battery in and when it was my turn, just plug in the power cord. Then you still have full power and in the event of a power failure, it does not crash. When it is off, you should also disconnect it from the Steom, especially if the battery is in it, because continuous charging is harmful and shortens the lifespan
When I gamble, the battery gets full and then I have to unplug it. But then I have less performance in the game.
It is only important for the performance that the power cord is plugged in. The battery actually has nothing to do with it (unless it may be broken)
Leave the battery where it is, leave the plug where it is. The battery is only charged when it is emptied. This means that the continuous current does not harm him, because he does not notice anything at all.
If you are permanently connected to the network, then the battery is out! This saves you charging cycles and the battery is "fresh" even after years!
