Microsoft has made the "sleep" function of Windows7 (hereinafter referred to as Win7) to the extreme, providing a variety of modes to choose from. Let's take a look at the differences and setting methods of various sleep modes in Win7 system.
First, short-term leave with "sleep" let the computer nap
usually use a computer, and often this is the case: the occasional need to leave for some time, long or short, not very fixed, such as This is the case at noon or at dinner. At this time, if you turn off the computer, it seems to be a bit of a big problem, because many programs and web pages have to be reopened when you come back, but if you don't shut down, the computer is wasting electricity, if there is anything to delay, time from one It’s not necessarily the hour to become two hours, it’s not a waste! It’s a bit of a dilemma. What should I do? In fact, this time you just need to enable the system's sleep function. When
need to wake up after sleep, simply press the power button or waving USB mouse can quickly return to work before leaving the state to continue to work. The speed can be much faster than restarting after shutdown! And all work before sleep can continue without restarting. At the same time, after entering the sleep state, the computer will only have the memory power-on to save the data of the working state, while the other hardware is all powered off, so the power consumption is very low.
What is a "sleep"?
computer in the sleep state, the power supply will be cut off other accessories in addition to memory, the operating state of the data stored in memory, so that when re-awaken the computer, you can quickly restore the previous state of sleep. If you need to leave the computer for a short time during work, you can use the sleep function to save power on the one hand and resume work quickly on the other.
but need to remind you that, because sleep does not save your desktop state to disk, so if the power failure during sleep state, unsaved information will be lost, so the system before sleep, You'd better save all the documents you need to save, "Ctrl+S", just in case.
Tip: how to enable sleep function, there are two, one is just click the Start menu shutdown button sleep among the other is a set time in which power management computer, as long as the computer has no operating After reaching the set time, it will automatically go to sleep.
In addition, enabling hibernate, and hybrid sleep patterns were similar method to leave and methods to enable the sleep function.
Second, the prolonged absence of "sleep" sleep
let the computer except for a short time away from your computer, sometimes we may also leave a longer period of time, such as running errands, even Maybe not at the computer one day, then at this time, shut down? Shut down, the program, document, webpage, data, etc. opened in the computer will be reopened the next time you turn it on! Do not shut down, if you don’t come back one day, the power is off, all the data is over, even if you sleep No, what should I do? Another very simple to enable a practical function -!! "Sleep"
is the data stored in memory compared to the sleep function, save data to the hard disk sleep function sucked in, into hibernation, all accessories No power, so the power consumption is almost zero! And even in the sleep state, even if the power is turned off, it will not affect the saved data. When the computer wakes up, all the work can still be restored normally. At the same time, because the data is saved on the hard disk, the speed of wake-up is much faster than restarting the computer.
What is a "sleep"?
"Sleep" is a portable computer designed primarily for power saving state, this state will save the open document file and a program to a hard disk (the memory state can be understood as the mirror image), When the next boot, the data is read from this file and loaded into physical memory. This file is the same size as physical memory. Since 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
must say that the hibernation feature is enabled, will generate a hibernation file with the same memory size in your system disk for data storage memory of them, the user should pay attention to whether your system disk There is enough space. For the stable operation of the system, the available space should account for about 10% of the system partition, that is, the 50GB system partition should have at least 5GB of free space.
Tip: If a long time without a computer, the best choice is to shut down. In addition, some networked programs, such as web applications that need to log in, instant messaging software (most instant messaging software can automatically reconnect after recovery, but can not save the original dialog window) and many network management programs may appear after recovery It is not working properly, so it is best to quit these programs before the system sleeps.
Third, leave an indeterminate time with "hybrid sleep" let the computer choose
Well, we were talking about the situation above short-term leave and leave for a long time, but sometimes life is always Full of variables - I don't know how long to leave, what should I do? Probably an hour, it could be a day with no sleep for fear of insurance, with sleep and feel better to sleep easy
Takeiteasy best way is to let the computer yourself the flexibility to choose -!! If uninterruptible power, from Memory recovery; if power is lost, it will be restored from the hard disk. And after this, is the "hybrid sleep" function!
enable hybrid sleep, the computer will automatically go to sleep, but the sleep state is different, among the data stored in memory will be saved in the hard drive at the same time, Therefore, 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 mixed sleep.
What is a "hybrid sleep"
Hybrid sleep is unique to Win7 and WinXP does not have, it combines all the advantages of sleep and sleep. After entering the hybrid sleep, the system will first save 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 there is no power failure, the system will recover directly from the memory, it only takes a few seconds; if the power is off, because the memory is still stored in the hard disk, you can also recover from the hard disk without worrying about the data. Lost.
Tips: Hybrid Sleep mode requires motherboard support S3 power management mode, but most motherboards support this mode. If your computer supports the Hybrid Sleep feature, then when you start Sleep after turning on the Hybrid Sleep feature, the system automatically goes into Hybrid Sleep.
Fourth, hang Download "away mode" so that the computer is running low consumption
In addition to the above several cases we are talking about will make the computer in a "hook", but there is another Richangshenghuo A very important application - hang up downloads. In the past, we usually started the download process, then turned off the monitor and speakers to let the computer run automatically. However, in this state, some non-working hardware will continue to consume power, such as video cards and sound cards. And Win7 them, we can enable a new "away mode", neither off the network, and will not affect the normal operation of the program to download!
enters Away mode power consumption of what is it? After entering this mode, the hard disk and memory will remain in working state, and the CPU enters a low power state (if the CPU does not support any energy saving technology, the leaving mode will cause the CPU to run at the lowest frequency × lowest FSB to reduce its power. Consumption), while unnecessary devices such as graphics cards and sound cards will be powered off. Although the power consumption is higher than the sleep mode, it is more power efficient than the normal boot download.
What is "away mode"?
leaving sleep mode is similar, but in the separated mode, file read and write operation can still continue, while maintaining a network connection, while the graphics, sound and other unnecessary devices in a closed state, in order to achieve energy saving .
However, "away mode" requires hardware support advanced power management, and the need to make some settings.
first need to shut down the hard drive into sleep and power management options all set to "never", or the hard disk are closed, how can download? Secondly, you need to modify the registry, open the registry editor with administrator privileges and navigate to "HKEY_LOCAL_MacHINESYSTEMCurrentControlSetControlSessionManagerPower", create a new "DWord (32-bit)" value named "AwayModeEnabled" in the right pane, and assign it. It is "1" (hexadecimal) and it takes effect after restarting. Then click on the "Sleep" button in the Win7 Start menu to automatically enter the "Away Mode".
Tip: Save the process of sleep, sleep in, do not press the computer power switch, this can cause problems not enter the system.
In addition, if you are using a laptop, so when the battery-powered sleep state, if the battery is running out, the system will automatically save memory data to the hard disk and then power off and go to sleep. At the same time, if it reaches the sleep time in the power plan, it will also enter the sleep state. Therefore, in general, the laptop only needs to enable the sleep function. If you want to save power, you can set the time to go to sleep in the power management options, so that you can be sure of nothing.
believe that many users will wonder - really do not shut it? Yes, after using the computer for so many years, we are used to closing it after work every day, closing it before going to bed, and even closing it when we go out to eat at noon. In fact, we did not seriously consider our habits, and did not carefully study the sleep and hibernation functions that Microsoft provided us. In fact, the features provided by Microsoft naturally have its usefulness, otherwise it will not always exist, and further strengthened in Win7. So after reading this article, you might as well try to experience the convenience and benefits of sleep and hibernation, and don't get used to kidnapping.
