Turn on hybrid sleep

In the "Power Options" window, find the "Sleep" option.

Expand the "After Sleep" option and find "Allow Hybrid Sleep".

Set the "Set to" option to "Enabled".

Sleep state introduction

In the sleep state, the computer saves all current work to memory and reduces the power supply to reduce power consumption. The screen turns off and the hard drive stops spinning, but the data in memory remains intact. When the computer is in sleep mode, it can be restored to its previous state by pressing the power button or other means of waking it up (such as keyboard, mouse).

Sleep cannot be powered off. If the power is cut off before the system is awakened, all the information in the memory will be lost. Your unsaved data documents will be lost. The system may also crash due to power outage. .

Hybrid sleep Hibernation introduction

Hybrid sleep is a special sleep mode. In this mode, the computer saves the current work to the hibernation file (hiberfil.sys) on the hard disk. . In this way, even if the power is cut off, the computer can load the hibernation file from the hard disk and restore it to its previous state. Hybrid sleep mode combines the advantages of sleep mode and hibernation mode, allowing for quick recovery while retaining data in the event of a power outage.

Most of the characteristics of hibernation state and sleep state are the same. The difference is that the power can be cut off, and waking up will be slower than sleeping, but much faster than normal booting.
