[Personal favorites] windows standby sleep

After switching the system to this mode, in addition to the memoryOthersThe power supply of the device will be interrupted, and only the memory depends on the power to maintain the data (because the memory is volatile, as long as the power is down, the data will be lost ). In this way, you can directly restore to the STANDBY state when you want to recover. This mode does not completely eliminate power consumption. Therefore, if the power supply in the standby mode is abnormal (for example, power failure), the next time the power supply can only be restarted, so data not saved before the standby mode will be lost. However, in this mode, the recovery speed is the fastest, generally within five seconds.

Sleep (Hibernate). After the system switches to this mode, the system automatically transfers all data in the memory to a sleep file on the hard disk, and then cut off the power supply for all devices. In this way, when the data is restored, the system will directly read the content of the Sleep file from the hard disk into the memory and restore it to the state before sleep. This mode does not consume power at all, so it is not afraid of Power Supply exceptions after sleep, but the cost is a hard disk space of the same size as the physical memory (fortunately, the current hard disk has exceeded the TB level, large-capacity hard disks are getting cheaper ). The recovery speed in this mode is slow, depending on the memory size and hard disk speed. Generally, it takes about 1 minute or longer.

Sleep, yesWindows VistaThis mode combines all the advantages of standby and sleep. After the system is switched to sleep state, the system transfers all the data in the memory to the Sleep file on the hard disk (this is similar to sleep), and then disables the power supply of all devices except the memory, maintain the data in the memory (similar to the standby mode ). In this way, when we want to recover, if there is no exception in the power supply during sleep, we can recover data directly from the memory (similar to the standby mode), which is fast; however, if the power supply is abnormal during sleep, the data in the memory is lost and can be recovered from the hard disk (similar to sleep), but the speed will be slower. However, this mode will not cause data loss in any case.

Because the sleep function has so many advantages, the power button on the Windows Vista Start Menu will switch the system to sleep mode by default. Therefore, we can make full use of this new function. After all, it is much faster to recover from sleep than to start from scratch. In addition, the sleep mode does not keep going. If the system is not woken up after a period of time (which can be set for a specific time), it is automatically transferred to sleep status, power off the memory to further reduce energy consumption.
