Question

The difference of a laptop and a desktop pc in power consumption?

Answer 1

Laptops typically use less power because they are designed to.

In order to get maximum run time per battery charge, the only options are higher capacity batteries or reduced power demand.

LCD screens use FAR less power than the old CRT monitors.

Answer 2

My desktop computer has a 650 watt power supply, and it probably uses about 2/3 of this wattage most of the time.  My laptop computer runs at 60 watts.

Answer 3

The power requirements are a lot different, though it depends on the configuration.  On my fast desktop it uses around 200W, while a laptop generally is less than 100W, sometimes around 50W or less.

Answer 4

Not only will your laptop take less energy to charge, once its batteries are full you don't have to keep it constantly plugged it. By taking advantage of off peak energy at night, an increased use of laptops could contribute to a dramatic decrease in overall power consumption.

Also, having batteries to charge rather than needing constant high power input allows laptops to be more easily powered by home based alternative energy sources.

Answer 5

They are about the same.....But much of the power are wasted in the in charging of the battery in the laptop! .

Answer 6

It depends on your PC Configuration. My PC uses alot more power than my laptop but it's because I've got 2 7950 GTKO Super Clocked Vid Cards, a 1100 watt PSU, and 8 Hard drives inside it. Also, your monitor has to be taken into effect as well external speakers, and anything else you have attached to your desktop that is built into your laptop.
