There is no reason why a laptop wouldn’t work just fine without its battery, as long as you take a few aspects into account. Make sure you are using the original power adapter, Power variations could cause components on the laptop’s motherboard to fail. if you live in an area where high-intensity electrical loads are likely can also damage your component.

And you should remember only to take out the battery when the laptop is turned off and unplugged.

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.
