A. The LCD display. In fact, almost half the power in most laptops is used by the screen, which is why dimming your screen can save you a lot of battery life. Below is a list of the major power consumers on your laptop. This list also applies to desktop computers, other than the screen figure.
LCD: 43%
Chipset: 21%
Processor: 9%
Graphics: 8%
Hard Drive: 5%
Network: 4%
Other bits: 10%
Obviously different systems will vary based on their components, but this gives a rough idea of where that battery power goes.
