How much electricity does a laptop consume compared with desktop computer?

Answer 1

A laptop has a battery pack and can be run on the battery for some time. It needs recharging which will use electricity but not as much as a desktop computer. The amount of power any computer will use depends on a number of factors such as the amount of time it is left on standby. You are probably better to leave the desktop on standby than to turn it off, because it could use more power to reboot all the time than when left on standby. This would only apply if you use the desktop daily or more often.

Answer 2

It varies quite widely by the model and what it's doing. It could be as low as 15 watts if charged and not doing anything, or as high as 60-70 watts if it's charging and doing something intense (3d games, major calculations, etc).

For example, a HP dv8t laptop can consume 73WH in one hour, which translates to 73W of energy use. For some 4-cell netbooks (40wh), they can have 8 hours of use, which translates to 5w power usage.

Answer 3

Laptops are definitely more energy efficient than desktops. Laptops use approximately 25% less energy than the desk version and operate on 30 watts of energy versus the desktop at 125 watts.

Answer 4

Because a laptop is smaller and has one main part with not that much parts in it. While the desktop has two main parts with tons of other parts in it. Plus it is bigger.

Answer 5

Because it is smaller
