Win7's three power modes are introduced

Windows 7 system provides three power modes. When working in different modes, the working frequency of computer hardware will change, which will affect the power consumption. 1. Balance mode power consumption depends on usage, heat dissipation is slightly higher
In the default setting of balance mode, the power supply plan of the graphics card is “Balance”. After the power is turned on, the processor heat dissipation mode is “active”, the minimum processor state is “5%”, and the maximum processor state is “100%”. The screen brightness when using the battery is 40%, and it is 100% after the power is turned on. That is to say, in balanced mode, full performance is provided only when the computer is active, and when it is inactive for a period of time, it automatically enters the power saving state. For most people, this is the most reasonable power plan.
2. Energy-saving mode has the lowest power consumption and lowest heat dissipation
In the default setting of energy-saving mode, the power supply plan of the graphics card is “Maximum battery life”. The processor cooling method is “passive”; the minimum processor status is “0%”, and the maximum processor status is “100%”. The screen brightness when using the battery is 40%, and it is 100% when the power is turned on. The energy-saving mode is more suitable for mobile office use. All hardware works in the lowest power consumption state, which is the mode with the lowest power consumption, so the heat dissipation is the lowest.
3. High-performance mode consumes the most power, and the computer directly turns into a heatsink
In the default setting of high-performance mode, the power plan of the graphics card is “highest performance”. The processor cooling method is “active”, the minimum processor status is “100%”, and the maximum processor status is “100%”. The screen brightness when using the battery is 100%, and it is 100% when the power is turned on. In high-performance mode, all hardware is in optimal working condition, so it consumes more power and the heat dissipation naturally increases.
