power plan refers to the planning of the power supply of various hardware devices in the computer. It is very easy to configure the power supply by using the power plan. For example, the user can set the power plan to automatically turn off the display after 10 minutes without the user operating the computer, and put the computer to sleep after not operating the computer for 1 hour. Not only that, but you can also set more detailed power settings, such as turning off the power of the hard disk after 20 minutes without the user operating the computer, reducing the processor usage and changing the system cooling method. Xiao Bian today's home system will be described in detail with you about three kinds of power plan:
Win7 support in a very comprehensive power plan, and built three power plans are "balanced", "energy "And high performance", the "balanced" power plan is enabled by default.
balance: This power plan will provide maximum performance when the system requires full performance, energy-efficient as possible when the system is idle. This is the default power plan and is suitable for most users.
Energy: This power plan will be possible for the user to energy saving, more suitable for laptop users use to go out, this program can help increase laptop computer outdoor life.
High performance: regardless of whether the user is currently required adequate performance, the system will maintain maximum performance run, it is the three planned one of the highest performance for a small number of users with special needs.
Using power plans
in understanding the power plan, users can replace the power supply solutions to meet the needs of the performance or energy efficiency. For laptops, using an energy-efficient power plan means having longer battery life, but there are some performance limitations; for desktop computers, using a high-performance power plan will keep the computer high-performance. There is no need to switch from low performance to high performance, but there is a higher power consumption relative to energy efficient power plans. If the user is using a laptop, you can move the pointer over the Battery icon in the notification area and a battery status and an indicator of the power plan will appear.
where the user can view the remaining amount of the battery, and the fast switching power plan, adjust screen brightness. If the user is using a desktop computer, the power plan cannot be used or changed directly in the notification area and needs to be changed in the power options of the control panel.
create a new power plan
preset power plans may not meet the needs of users of power management, the user can directly change the power plan, or create a new power plan. Win7 provides very detailed power management settings, and users can customize power management in all aspects of the process when creating a new power plan. Users can follow these steps:
First, open the Control Panel "Power Options" panel and click on the left side of the "Create a power plan" link, switch to the "Create a power plan" panel, such as The figure shows.
here to select a power plan template to refer to as a new power plan, and enter a name for the new power plan.
after selecting a template and enter the program name, click "Next" button, select the computer's sleep settings and display settings, as shown below. Here
will ask the user to select a standby time before turning off the display, and causing the computer to enter the standby time before the sleep state. The interface between the desktop and the laptop may be different, but the content selected by the user is the same. After
click the "Create" button, a new power plan appears in the "Power Options" panel. Once created, the user also needs to click the "Change Power Settings" link to the right of the new power plan, click the "Change Advanced Power Settings" link in the "Edit Plan Settings" panel, and the Power Options dialog opens. ,As shown below.
in the "Power Options" dialog box can be a very careful power management settings, like switching power plans, as required in the dialog box, click the "Change settings that are currently unavailable" link to be able to get all the changes Set permissions.
saving mode
have an energy-saving mode called standby in previous versions of Windows, but has been replaced in Win7 sleep in. Hibernation is an energy-saving mode in previous versions of Windows. By putting the computer into hibernation, you can save the contents of the current desktop and the data in the physical memory to the hard disk, and directly read the data from the hard disk at boot time. Memory to allow the user to quickly switch from the off state of the computer to the working state.
Win7 sleep is very important in an energy-saving mode, and hibernation is similar to an energy-saving mode. When the computer is switched to sleep, the system will turn off all devices except physical memory that can go to sleep, which allows the desktop to be completely restored before it goes back to sleep when the user resumes the computer state. The physical memory power that is in a sleep state is very low, so users don't have to worry about sleep damage to physical device components and excessive power consumption.
in the absence of a program to prevent computer to sleep, go to sleep and resume from sleep state takes only a few seconds, the most important is the use of sleep that allows users to quickly from the working state of the computer on and off Switch between states. For example, when a user suddenly needs to leave to print a document while at work, the computer can be switched to sleep state, and the computer is in a state of maximum energy saving.
