A variety of Windows7 sleep patterns

a short leave with "sleep" let the computer nap for a while

Usually use a computer, often have such a situation: occasionally need to leave a period of time, or long or short, not very fixed, such as at noon or at night when eating is so. And at this point if the shutdown, it seems a bit of a fuss, because the time to return a lot of programs, Web pages will be reopened, but if not shut down, the computer is wasted electricity in vain, if there is any delay, the time from one hours into two hours is not necessarily, In fact, you just have to enable the system's sleep function.

When you need to wake up after going to sleep, just click on the power button or shake the USB mouse to quickly resume working before you leave. At the same time, after sleep, the computer will only have memory power to save the working state of the data, while the other hardware is all power off, so the electricity consumption is very low.

　What is "sleep"?

When the computer is asleep, it will cut off the power of other parts except for the memory, the working state of the data will be kept in memory, so that when you wake up the computer, you can quickly restore the working state before sleep. If you need a short period of time to leave the computer, you can use sleep function, on the one hand can save electricity, on the other hand can quickly resume work.

Tip: There are two ways to enable sleep, one is in the Start menu of the Shutdown button in the direct click of sleep, the other is in the computer power management set time, as long as the computer has been no one to operate and reached the set time, it will automatically enter the sleep state.

In addition, the methods for enabling hibernation, mixed sleep, and leaving modes are similar to those used to enable sleep.

Two, long time does not use "sleeps" to let the computer sleep a good night

In addition to a short time away from the computer, sometimes we may also leave longer time, such as out of work, or even a day may not be next to the computer, then the end of the shutdown? Shutdown, the computer open the program, documents, Web pages, information and so on in the next time you turn on the open again! It's simple! Enable another practical feature-"Hibernate"!

Compared to the sleep function is to save the data in memory, hibernation is to save the data to the hard disk, into hibernation, all accessories do not power, so the power consumption is almost zero! And in hibernation, even if the power off, will not affect the data has been saved, when the computer wakes up, all work can still be normal recovery. Also, because the data is stored on the hard disk, the wake-up speed is much faster than restarting the computer.

　　What is "Hibernate"?

Hibernation is a power-saving state designed primarily for portable computers, in this state, the open documents and programs are saved to a file on the hard disk (which can be understood as a mirrored memory state), which reads the data from the file the next time it is turned on and loads the physical memory, which is the same size as the physical memory. Because the memory written to the hibernation file is a disk file, read faster than when the disk is more efficient to access the normal startup, so much faster than normal boot.

It is also important to say that when the Hibernate feature is enabled, a dormant file with the same size as your memory will be generated on the system disk to store the data in memory, and users should be aware that their system disks have enough space. For the stable operation of the system, the free space should occupy about 10% of the system partition, that is, the 50GB system partition should have at least 5GB free space.

Tip: If you do not use the computer for a long time, it is best to choose shutdown. In addition, some networking programs, such as the need to log in to the Web application, instant Messaging software (most instant messaging software can automatically reconnect after recovery, but not the original dialog window) and many network management programs after the recovery may appear to be not normal use of the situation, It is therefore best to quit these programs before the system sleeps.

　　Three, leave time may use "mixed sleep" lets the computer choose by oneself

OK, we tell each other a short time to leave and a long time to leave, but sometimes life is always full of variables-I do not know how long to leave, how to do? may be an hour, but also may be one day, with sleep is not safe, with hibernation and feel as easy as sleep!

The best way to do this is to make the computer flexible enough to recover from memory if it is not powered off, and to recover from the hard drive if it is powered off. And this, is the "Mixed sleep" Function!

When you enable mixed sleep, your computer automatically goes to sleep, however, unlike sleep, the data stored in memory is also stored in the hard drive, so even if the power loss does not result in lost data, and wake-up of the computer can also be faster recovery, which is the advantage of mixed sleep.

　What is "mixed sleep"

Mixed sleep is unique to the Win7 and WinXP, and it combines all the benefits of sleep and hibernation. After entering mixed sleep, the system will first save the data in memory to the hard disk, while cutting off the power of other devices except memory. In the recovery, if there is no blackout, then the system will restore directly from memory, only a few seconds, if the power outage, because the hard disk also saved the state of memory, so you can recover from the hard disk, do not worry about data loss.

Hint: The mixed sleep mode requires the motherboard's power management support S3 mode, although the general motherboard supports this mode. If your computer supports mixed sleep, start sleep after you turn on the mixed sleep feature, and the system will automatically go into a mixed sleep state.

　　Four, hangs the machine to download uses "leaves the mode" to let the computer low consumption run

In addition to the above we say several situations will let the computer in the "Hanging Machine" state, daily life there is another very important application-hanging machine download. In the past, we usually open the download program, and then turn off the monitor, speakers to let the computer run automatically, but in this state, some of the hardware will continue to power consumption, such as graphics cards, sound cards and so on. And Win7, we can enable the new "Leave mode", will not break the network, and will not affect the normal operation of the download program!

What is the power consumption situation that goes into the departure mode? After entering this mode, the hard disk, memory will remain in the working state, while the CPU into a low-power state (if the CPU does not support any energy-saving technology, then leave mode will allow the CPU to the lowest frequency multiplier x minimum FSB run to reduce its power consumption), Unwanted devices, such as video cards and sound cards, will be powered off. Although the power consumption is higher than the sleep mode, but compared with the normal boot download, it is more electricity-saving.

　　What is "leaving mode"?

Leave mode is similar to sleep, only in the left mode, the file read and write operation can continue, while maintaining network connectivity, and graphics cards, sound cards and other unnecessary equipment in the shutdown state, in order to achieve energy-saving purposes.

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

First of all, the power management to turn off the hard drive and hibernate options are all set to "never", otherwise the hard drive is closed, how can I download? Secondly, you need to modify the registry, open Registry Editor with Administrator privileges, and navigate to the Hkey_local_ Machinesystemcurrentcontrolsetcontrolsessionmanagerpower ", create a new DWord (32-bit) value named" Awaymodeenabled "in the right pane and assign a value of" 1 " (hex), which is restarted to take effect. Then click on the "Sleep" button in the Win7 Start menu to automatically go to "Leave mode".

Hint: In the sleep, hibernate disk process, do not press the computer power switch, otherwise may cause the problem which cannot enter the system.

In addition, if you are using a laptop, then in the battery-powered sleep state, if the battery is about to run out, the system will automatically save the memory data to the hard drive and then turn off the power and into hibernation. Also, if you reach hibernation in the power Plan, you go into hibernation. So in general, a laptop can only be enabled for sleep. If you want to save power, you can set the time to hibernate in the power management options, so you can guarantee a foolproof situation.
