If you are low on energy working with a notebook, I’m not surprised Notebooks are not ergonomic. The location of screen and keyboard strains, upper back, neck, eyes and shoulders. On top of that, they are usually not as well shielded as desktops, the electromagnetic exposure increases our overall “stress” levels. Stress means here not necessarily stress out, but the stress on the bodies energy, with higher fatigue after the work is done.

The only way to use a notebook is to use a docking station with external monitor, ergonomic keyboard and mouse, or a notebook stand to raise the screen off the desk and use external mouse and keyboard. And only occasionally “stand-alone”.

Heat: Many notebooks get really hot, i.e. that’s wasted energy. Desktops can operate much cooler -> less wasted energy. If the notebook runs off the battery, you wasted probably about 40-50% of the energy you put in.

First, the loss in the power supply, usually they are 60 to 80% efficient
Second, the battery is about 80% to 90% efficient.
You might use less power in total, but not in performance per watt.

Unless the battery is charged by a solar panel. But who has that setup?

Somewhere around 80% of the total energy balance of a computer is used to manufacture the components and to built the computer.

Desktops have a much longer life cycle. For example a GreenMachineShop desktop is built to run stable for 5 years. Due to the higher heat and the way the electronic is designed and components used, most desktops and notebooks are built to run stable for only 2-3 years. There is also a higher failure rate for notebooks. They need to be shipped back and forth. Parts in a desktop, if they break down can be replaced by off-the-shelf parts, the whole system doesn’t need to be replaced.

I highly doubt that the energy and environmental balance of a notebook comes even close to compete with a good quality desktop system. Especially now that the new low wattage AMD and Intel CPUs are available.

Desktops are also easier to recycle. Easier to take apart, steel can be just recycled. Many notebooks have a lot more plastic parts and take more time to take apart.
