Three power modes for Windows 7

Failure phenomenon:

The Windows 7 system provides the following three power modes, working in different modes, and the operating frequency of the computer's hardware changes, which can affect consumption.

Solution:

1. Balance mode power consumption according to the use of the situation, the scattered heat slightly higher

The power plan for the video card is "balanced" under the default settings for balanced mode. When the power is switched on, the processor is thermally active, with a minimum processor state of "5%" and a maximum processor state of "100%". When the battery is used, the screen brightness is 40% and the power is 100%. In other words, in the balance mode only when the computer is active to provide full performance, when the time is not active, it will automatically enter the power-saving state. For most people, this is the most reasonable power plan.

2. Energy-saving mode power consumption minimum thermal dissipation

The power plan for the video card is "Maximum battery life" under the default settings for energy-saving mode. The processor is thermally "passive" with a minimum processor state of "0%" and a maximum processor state of "100%". When the battery is used, the screen brightness is 40%, and the power supply is 100%. Energy-saving mode is more suitable for mobile office use, all hardware in the state of the lowest power consumption, is the minimum consumption of electricity mode, so the lowest heat dissipation.

3. High-performance mode power consumption, computer direct transformation Radiator

The power plan for the video card is "highest performance" under the default settings for High-performance mode. The processor is thermally active, with a minimum processor state of "100%" and a maximum processor state of "100%". When the battery is used, the screen brightness is 100%, and the power supply is 100%. In high-performance mode all hardware is in the best working condition, so it will consume more power, and the thermal dissipation will naturally increase.
