How to set up various sleep modes of Windows 7

Usually use a computer, we often choose to shut down when leaving, generally think that this is both power-saving and safe. However, this is just a habitual practice for everyone. Many people have not thought about whether this is reasonable. In fact, since Windows XP (hereafter referred to as WinXP) system, Microsoft has provided "Standby" and "Hibernate" functions, and to Windows 7 (hereafter referred to as Win7), this feature has been strengthened, providing more A rich selection of modes to choose from. Let's take a look at what kind of different situations we should choose for Windows 7 to "sleep". First, leave for a short time with "sleep", let the computer take a nap. Usually use the computer, often there is such a situation: occasionally need to leave for a period of time, long or short, not very fixed, such as when eating at noon or at night. 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 you need to wake up after entering the sleep state, you only need to press the power button or shake the USB mouse to quickly resume the working state before leaving and 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 "sleep”? When the computer is in a sleep state, it will cut off the power of other accessories except the memory, and the working state data will be stored in the memory, so that when the computer is reawakened, the working state before sleep can be quickly restored. 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. However, you need to be reminded that because the sleep state does not save the desktop state to the hard disk, if the power is cut off during sleep, the unsaved information will be lost, so before the system sleeps, you better save it. The documentation is all & ldquo; Ctrl + S & rdquo; save it, just in case. Tip: There are two ways to enable the sleep function. One is to click sleep directly in the shutdown button of the start menu, and the other is to set the time in the computer power management, as long as the computer has no one to operate and achieve this setting. After that time, it will automatically go to sleep. In addition, the methods for enabling hibernation, mixed sleep, and leave mode are similar to the method for enabling sleep.
