Isn't it?

nospam
no, it isn't.

Why isn;t it. The battery is the power supply it's what supplies power to the circuitry so it is the power supply.

nospam
the power supply refers to the part that plugs in the wall, not the battery.

Whisky-dave
Not in the real world where we need to distiquish between such things.

nospam
yes in the real world, which is why there are two separate names for them.

Whisky-dave
The part that plugs into the wall is the power supply unit or PSU and adapter combined, because it adapts the mains power to DC that the laptop uses to run the laptop and charge the battery. Some call them power bricks.

nospam
so you agree that it's called a power supply, although it does have other names too.
