Battery

The battery on a laptop serves as its life-line. A laptop will work without a battery if it is receiving power from a power adapter.

The battery allows you to be more mobile without having to be near a power outlet for an extended period of time. Most laptop batteries will last for about 1.5-2 hours before needing to be recharged. If your battery dies or has a defect you can buy a new one from your computer’s manufacturer or a local computer or electronics store.


AC Adaptor
The AC Adaptor is the source of electric power for a laptop. The power adapter does two jobs when it is plugged in. It powers the laptop and charges the battery.

Did all the laptops look the same?

What did they have in common?
