Advantages of Vista's sleep state

Windows Vista uses the system sleep state (Sleep) as the default energy-saving mode. Vista's sleep state combines the advantages of traditional standby or hibernation: when the system goes to sleep, it automatically saves all the data in the memory to the hard disk (similar to hibernation), but does not cut off the power to the memory, in memory The data is also maintained (similar to standby), which is equivalent to adding a double insurance to the system. If there is no power loss during sleep, then when the system is restored, the system will recover from the standby state, and it will return to the normal state in a few seconds. If the power is lost in the middle, then the computer will be in a sleep state when it is restored. The same recovery, as long as more than a minute to return to normal. In the default installation, Windows Vista uses its energy-saving mode called Balanced plan.
In Windows Vista, there are three preset saving modes, namely Balanced, Power Saver and High Performance, which can be selected in the power options in the control panel. For desktop users, if energy savings are not your concern, you can choose High Performance mode directly, so your system won't go to sleep after 1 hour; for notebook users, It may be more sensible to choose the Power Saver mode.
If all three preset modes do not meet your requirements, you can modify the settings yourself after selecting one of them, such as desktop users, although using the default Balanced mode, The idle time for entering the sleep state is modified to 2 hours or more. Of course, a better option is to create a self-defined energy-saving solution: click Create a power plan in the left panel and set it up one by one.
For Windows Vista, the Power button in the Start menu is preset to go to sleep instead of the traditional shutdown. The debate has been fierce. Whether Microsoft is wise or not may only have time to prove it. However, for most users, it can only be passively accepted: by clicking the small arrow next to the Shutdown and Lock button, you can find the corresponding option to turn off the shutdown. In fact, there is an easier way to change the default value of the Power button back to the traditional Shut Down, so that when you click the Power button, the system will automatically shut down.
To achieve this, you need to modify the selected preset or custom energy saving scheme. In the example shown above, the selected energy saving scheme is Balanced mode, click the Change advanced power settings link, and then set the Start menu Power Button in the pop-up window. Change to Shut Down.
