How to choose what kind of "sleep" method for Windows7

Computer shop news, long time is not used "sleep", let the computer sleep well

In addition to short-term computer separation, sometimes we may still separate longer time, such as going out Maybe even one day is not at the computer, then this time is not shut down? Shutdown, the open program, documents, web pages, data, etc. in the computer will not be turned on once again! Do not shut down, if it is not back in a day, the power is off, all the data is over, that is, it is used Sleeping is not good! What should I do? It's very simple! Enable another applicable function ——“hibernate>!

Contrast sleep function is to keep data in memory, hibernation function is to keep data to hard disk, after going to sleep state All accessories are owed to the power, so the power consumption is almost zero! And even if the power is turned off in the sleep state, it will not affect the data that has been retained. When the computer wakes up, all the work can still be resumed normally. At the same time, because the data is kept on the hard drive, the wake up is much faster than starting the computer from scratch.

What is "hibernation"

 Hibernation> is a power-saving state that is primarily designed for portable contestants. In this case, the open documents and files are kept in a file on the hard disk (can be understood as memory status) Mirror), when the next boot, read data from this file, and load physical memory, this file is as small as physical memory. Because the file written by memory during hibernation is a disk file, the speed of reading is much higher than that of accessing the disk during normal startup, so it is much faster than normal startup.

In addition, it must be said that after the hibernation function is enabled, a hibernation file that matches the size of your memory will be generated on the system disk to store the data in the memory. Users should pay attention to their own system disk. There is enough space. For the constant operation of the system, the available space should be 10% of the system partition, that is, the 50GB system partition should have at least 5GB of free space.

Reminder: If you don't need a computer for a long time, it is best to choose to shut down. In addition, some networking programs, such as Web applications that require login, instant messaging software (the instant messaging software can automatically connect from the beginning after recovery, but can not retain the original dialog window) and a lot of collection management in the recovery It may be a situation that is not working properly, so it is best to exit these programs before the system sleeps.

Second, the hang-up download with "separate mode", let the computer run low-cost

In addition to the above we will say that several situations will make the computer in the "hang-up" situation, daily life There is another very important application —— hang up download. In the past, we always open the download program, and then block the display, speakers to let the computer run automatically, but in this situation, some non-working hardware will continue to consume power, such as graphics cards, sound cards. And Win7, we can enable the new "separate mode", which will not break the network, and will not affect the normal operation of the download program!

What is the power consumption situation when entering the separate mode? ? After entering this mode, the hard disk and memory will be connected to the working condition, and the CPU enters a low power state (if the CPU does not support any energy saving technology, the separate mode will let the CPU run at the lowest frequency & times; the lowest FSB to lower its Power consumption), while unwanted devices such as graphics cards and sound cards will be powered down. Although the power consumption is higher than the sleep mode, it is still more power-saving than the normal boot download.

What is "separate mode"

The split mode is similar to sleep, except that in the split mode, the file read and write operations can continue, and the connection collection is connected, and the unnecessary devices such as the video card and the sound card are in a blocked state to achieve energy saving. .

However, "separate mode" requires hardware devices to support advanced power management and requires some settings.

First of all, you need to set all the options for blocking the hard disk and entering hibernation in the power management to “Never”, otherwise the hard disk is blocked, how can you download it? Secondly, you need to change the registry, open the registry editor with the administrator privileges and navigate to “HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Power”; create a new name in the right pane called “AwayModeEnabled”. ;DWORD (32-bit)& rdquo; value, and assigned to “1& rdquo; (hexadecimal), it will take effect after restart. Then click on the “sleep” button in the Win7 start menu to automatically enter the "separate mode".

Reminder: During the process of saving sleep and hibernation, don't talk about the power switch of the machine. Otherwise, it may cause problems that cannot enter the system.

In addition, if you are using a laptop, if the battery is about to run out during battery-powered sleep, the system will automatically retain the memory data to the hard disk and then block the power supply and enter the sleep state. At the same time, if it reaches the moment when the power supply intends to go to sleep, it will enter the sleep state. In general, laptops only need to enable sleep. If you want to save power, you can set the time to enter the sleep state at the power management option, so that you can be sure that nothing has disappeared.

Believe that many users of the city thinks —— really do not need to shut down? Yes, after using the computer for so many years, we have become accustomed to blocking it after every national shift, blocking it before going to bed, and even blocking it when we go out to eat at noon. In fact, we did not really consider our habits, and did not carefully study the sleep and hibernation functions that Microsoft supplied us. In fact, the function provided by Microsoft naturally has its use, otherwise it will not always exist, and further enhanced in Win7. So after reading this article, you may wish to take the exam and experience the convenience and contact between sleep and hibernation. Don't get used to kidnapping.

Third, use a short-term separate "sleep", let the computer take a nap for a while

Daily use of the computer, there are often such situations: occasionally need to separate a period of time, long or short, not very Fixed, like the time of lunch or dinner at night. At this time, if it is turned off, it seems that some small problems are done, because there are many times when the time comes back, and the webpage has to be opened from the beginning, but if it is not shut down, the computer is white and open, and if there is anything else. It’s not inevitable that it will take two hours to make an hour from an hour. It’s not even extravagant! It’s a bit of a mess, what should I do? In fact, you only need to enable the system's sleep function at this time.

When you need to wake up after entering the sleep state, you only need to press the power button or sway the USB mouse to quickly restore the working condition before the separation and continue to work. Speed ​​can be started much faster than starting up after shutting down! And all work before sleep can continue without starting from scratch. At the same time, after entering the sleep state, the computer will only be powered on the memory to retain the data of the working condition, while other hardware is completely powered off, so the power consumption is very low.

When the computer is in a sleep state, it will cut off the power of other accessories except the memory, and the working status data will remain in the memory, so that when the computer wakes up from the beginning, it can quickly restore the working condition before sleep. If you need to separate the computer in a short time during work, you can use the sleep function, which can save power on the one hand, and resume work quickly on the other hand.

However, you need to be reminded that because the sleep condition does not keep the desktop status on the hard disk, if the power is cut off during sleep, the unreserved information will be lost. Before you sleep, you'd better keep all the documents you need to keep, Ctrl+S” keep it, just in case.

Reminder: There are two ways to enable the sleep function. One is to click on the sleep button on the start button of the start menu, and the other is to set the press time on the power of the contested machine. As long as the computer has never been After the person has operated and reached the set time, it will automatically enter the sleep state.

In addition, the modes that enable hibernation, assimilation sleep, and split mode are similar to those that enable sleep.

Fourth, separate time is not sure to use “ assimilation sleep & rdquo; Let the computer choose their own

Well, above we talk about the short-term separation and long-term separation, but sometimes Life is always full of variables — — I don't know how long to separate, what should I do? It may be an hour, or maybe a day, sleep is not safe, sleep is not as good as sleep!

Take it easy! The best way is to let the computer choose to be flexible —— Exhausted, it will be restored from the memory; if it is determined, it will be restored from the hard disk. And this is the "synonymous sleep" function!

After enabling assimilation sleep, the computer will automatically go to sleep, but the difference with the sleep situation is that the data retained in the memory will remain at the same time. The hard disk is edged, so that even if the power is turned off, it will not cause data loss. When you wake up the computer, you can recover at a faster speed. This is the advantage of assimilation sleep.

What is <;Assimilation Sleep>

Assimilation sleep is unique to Win7 and not available in WinXP. It links all the benefits of sleep and dormancy. After entering assimilation sleep, the system will first keep the data in the memory to the hard disk, and cut off the power supply of other devices except the memory. In the recovery, if it is not broken, the system will recover directly from the memory, it only takes a few seconds; if it is determined, because the memory still retains the memory, it can also be recovered from the hard disk, do not worry Data is missing.

Reminder: Assimilation sleep mode requires the power supply of the motherboard to support the S3 mode, but the general motherboard supports this mode. If your computer supports the assimilation sleep function, then when you start the sleep after turning on the assimilation sleep function, the system will automatically enter the assimilation sleep state.
