Win7 selects

When the computer is not needed for a while, you will choose “Shutdown”, “Mixed Shutdown”, “Sleep”, “Hibernate” or “Mixed Sleep”. According to a survey conducted by Microsoft for Windows 7 users, 57% of desktop users and 45% of laptop users would choose to turn off their computers instead of putting them into sleep mode.

Note: The above image is from a Microsoft survey.

In this regard, we will introduce each option one by one to find the best choice for you. However, since each option has its own characteristics, we have analyzed it in two cases. In addition, I will answer some of the most worried questions.

First, if you want to enter a new session after startup:

1. Select “Shutdown&

If you select “Shutdown”, the system will notify you that Run applications that notify them to save data and settings. After that, the user session of each logged in user will be closed and the service will be closed. The system then notifies the device and closes the system session, saving the pending data. Finally, the system sends a signal through the ACPI interface to shut down the computer.

“Shutdown” is more energy efficient, and the shutdown speed is very fast. After startup, you will enter a new session. In addition, if you need to change the hardware device or the system is faulty, it is generally recommended to use shutdown to avoid errors.

2. (Best) Select “Hybrid Shutdown&##>

If you select “Mixed Shutdown”, the system will close all user sessions as “Shutdown”. But the system will no longer shut down the kernel session, but will sleep it. Since it is only necessary to read the hibernation file and re-initialize the driver at startup, the startup speed is much faster than selecting "Shutdown". “Mixed Shutdown” is more energy efficient and faster to start. It should be noted that this is a new feature added to Windows 8, which replaces the shutdown by default.

Second, if you want to get into the working state after starting:

1. Select “Sleep>

If you select “Sleep>, then the system will close Part of the equipment. At this time, generally only the memory is still powered up to maintain the memory data. Sometimes, in order to wake up from other methods, the network card, USB interface, etc. will be powered on. After waking up, the user can quickly enter the working state.

2. Select “hibernate>

If you select “hibernate>, the system will save the system state and memory contents to a file on disk before shutting down the computer ( Hiberfil.sys). The file will be re-read and the contents will be restored to memory during recovery. With the sleep mechanism, users can not only get into the working state faster, but also completely avoid power consumption during shutdown.

3. (Best) Select “Hybrid Sleep&<<>

If you select “mix sleep”, the system will save the system status and memory data to sleep. Disk. This is enabled by default on desktop computers. When you wake up your computer, if the computer's power is not cut, you can quickly enter the working state; if the power has been cut off, you can read the hibernation file on the disk, restore the working state, and your session content will not be lost.

For computers that use batteries or have uninterruptible power supplies, it is more common to sleep by default and to sleep when the battery is low.

III. Troubleshooting

1. What is “new conversation”?

The new state is the state that the user chooses to "turn off" and then start the system again. The user can open the required software to enter the working state, but it takes a long time. The startup speed is just the time it takes to get into a new session.

2. What is "work status”?

The working state is a state in which the user can start working immediately. If you are browsing some web pages, then the working status may be to open a browser, music player, instant messaging software, and so on. The speed of entering the working state is the time required to enter the working state.

3. What is the power consumption during sleep? Will the components be worn out?

As mentioned above, the system generally shuts down other devices during sleep, only powering up the memory to maintain data. This situation consumes very little power (about 7.5W or so), and because the component is at rest, its losses are not too large and can be neglected.

4. The hibernation file is seriously "swallowed" disk space, should it be decisively deleted?

According to some optimization software or security software, the hibernation file severely engulfs disk space, so it is listed as one of the mandatory deletion items. However, the hiberfil file (hiberfil.sys) only accounts for about 75% of the physical memory capacity by default. If you feel that the disk space is tight, you can also adjust the reserved size of the hibernation file.

The hibernation file is used to save hibernation data. If you execute “powercfg /hibernate off” to reclaim this space, this means that hibernation, mixed sleep, and fast boot (hybrid shutdown) will be completely disabled. Considering the many benefits of using features such as hibernation, and the small amount of space gained after deletion, you should not delete it unless disk space is extremely limited.

5. If you can't wake up after sleep, how do you troubleshoot?

First of all, please confirm whether some system files are deleted as junk files by some optimization software or security software. Otherwise, please check if the BIOS settings have been changed. See if the motherboard supports the ACPI interface. In addition, driver updates, system updates, and some third-party software can cause your computer to wake up after sleeping.

IV. Reflection habits

Today is Earth Day, a worldwide environmental protection activity that began in the United States in 1970. The event aims to evoke the awareness of human beings to protect the earth and protect their homes, promote the coordinated development of resource development and environmental protection, and improve the overall environment of the earth.

However, today, our understanding of environmental protection is not deep enough. Many users will continue to turn on the computer when they leave briefly, instead of sleeping or shutting down, which creates a huge waste of energy.

Under normal circumstances, if the computer does not need to be used for a while, you should choose "sleep", "sleep", or set the length of the above two "mix sleep" because of this Being able to quickly restore work status can save a lot of time, which is more reasonable than “Shutdown”. “Shutdown” should be used when hardware changes or system failures are required.

Why are we going to resist these new ways? Rely on the "sleep" and other functions to quickly enter the work state, far than you are in the process of deleting the startup item, shutting down the service, "optimizing" system, cleaning up "garbage", scoring the computer, etc., using the shutdown, traditional boot and then Get a hint & ldquo; You have shared xx seconds this time, your boot speed beats xx% of the country's computers … …& rdquo; is much more practical and makes sense.
