What if the computer goes into sleep mode?

The computer enters sleep mode, and you can wake up from sleep by pressing the power button.

Computer sleep mode is a mode in which the computer is in standby state, which can be set through the "Power Options" menu of the computer.

It can save electricity for you, which is relatively "environmentally friendly", which can save the tedious boot process and increase the life of the computer.

Extended data

The new energy-saving mode Windows operating system has already joined standby, hibernation and other modes, while Windows

Vista has added a new mode called sleep, but many people are still used to turning off their computers completely when they are not using them. In fact, making full use of these modes can not only save power consumption, but also restore the system to normal working condition in the shortest time.

These three modes are defined as follows: Standby. After the system switches to this mode, except for the memory, the power supply of other computer devices will be interrupted, and only the memory relies on electricity to maintain the data inside (because the memory is volatile, as long as the power is cut off, the data will be gone). In this way, when you want to recover, you can directly return to the state before standby.

This mode is not completely without power, so if the power supply is abnormal (such as power failure) in standby mode, you can only restart the machine next time, so the unsaved data before standby will be lost. However, this mode has the fastest recovery speed and can be recovered within five seconds.

Hibernation: After the system switches to this mode, the system will automatically transfer all data in the memory to a hibernation file on the hard disk, and then cut off the power of all devices. In this way, when restoring, the system will directly read the contents of the hibernation file from the hard disk into the memory and restore it to the state before hibernation.

After switching the system to sleep, the system will transfer all the data in the memory to the hibernation file on the hard disk (similar to hibernation), and then turn off the power of all devices except the memory, so that the data in the memory remains unchanged (similar to standby).

In this way, when we want to recover, if the power supply is not abnormal during sleep, we can recover directly from the data in the memory (similar to standby), which is very fast; However, if the power supply is abnormal during sleep and the data in the memory has been lost, you can recover from the hard disk (similar to hibernation), but the speed will be slower.

However, in any case, this mode will not lead to data loss. 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. So we can make full use of this new function. After all, recovering from sleep is much faster than starting from scratch.

In addition, sleep patterns do not always last. If the system does not wake up after entering the sleep mode for a period of time (the specific time can be set), it will automatically enter the sleep state and turn off the power supply to the memory to further save energy.
