If there is more current available then the computer requires to run it will charge the battery with the excess, and if it's not enough, the battery will provide power to top up the difference.
How does a laptop charge a battery?
A laptop uses power from the wall outlet when plugged in. It charges the battery while connected. The laptop operates on AC power when the battery is fully charged. It does not consume battery power in this mode, except during a power interruption. Battery health is another vital aspect. Modern laptops are designed with smart charging technology.
Can a laptop battery be plugged into a wall outlet?
Most modern computers have the capacity to manage this scenario. Once a laptop battery is fully charged and the laptop is used while plugged in, the battery is usually bypassed for power consumption, meaning the laptop runs directly on power from the wall outlet. This means it should not harm the battery directly in terms of charge cycles.
Why does my laptop not use battery when plugged in?
The laptop uses ac adaptor when plugged in. Not battery. If you take a look at the battery icon when plugged in, you would see it goes to 100, then gets discharged to some level and charging back again. So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill battery?
