Notebook power draw by component type
Our buds over at WebWorkerDaily are sharing info from Microsoft engineers on power consumption in modern notebooks. Some of you are probably already aware that the display draws the most power. Did you know it was nearly 50%? This is why I favor the newer LED backlit screens and more importantly, set my brightness to the lowest usable level. All this week at CES, for example, I’ve used my MacBook at the minimum brightness. It takes getting used to, but I’m accustomed to it as I do the same on all of my mobile devices; even my iPhone.
The above chart also exemplifies why we’re not witnessing vast increases in overall battery life from SSD drives. When the hard drive only accounts for 5% of power consumption, you’re going to see a minimal benefit.
