Laptops
Usually, notebooks are more modest than desktop PCs when it comes to the energy requirements. On average, otebook batteries last for less than two hours, so energy saving is an important issue for those who are away from a plug point for long durations.
If you want to achieve maximum battery runtime then it’s essential for a notebook to ave energy-efficient components. Here’s a comparison: while desktop processors such as AMD’s Athlon 64 X2 000+ or Intel’s Core 2 Duo E6400 require up to 65 Watts, mobile CPUs make do with a maximum of 35 Watts. The PSU is of importance in matters of energy efficiency. Some PSUs unnecessarily convert 7 Watts into heat. The warmer the external power supply unit, the higher the electricity consumption. Apple’s MacBooks or Acer-models have intelligent charging electronics that ensure the current-flow sinks below 0.1 Watts after the battery is charged. alues less than 3.0 Watts, in |
