No, a laptop does not use battery power when plugged in, except in certain situations. When a laptop is connected to a power source, it primarily draws power from the electrical outlet. However, it may occasionally use battery power for a few reasons, such as during temporary interruptions in the power supply or when it is in a power-saving mode.
When you have a power supply, it needs to provide the correct voltage. If there is enough current it will run the computer. 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.
When a laptop is connected to a power source, it primarily draws power from the electrical outlet. However, it may occasionally use battery power for a few reasons, such as during temporary interruptions in the power supply or when it is in a power-saving mode. This is designed to ensure that the laptop continues functioning without interruption.
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?
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.
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.
