Why does a lab top come with a built in battery in stead of a power cord like desk top does?

A laptop is designed to be portable, which is why a laptop has an internal battery. Laptops can also be powered using a cable plugged into the mains. This power cable is also used to recharge the battery. One advantage of the internal battery in a laptop is, if there is a sudden power outage, the battery will continue to power the laptop until the battery runs down. In a power outage, a desktop computer would simply stop working.
