Sleep and hibernation modes are undoubtedly examples of computer energy-saving modes. They can save resources for users when the computer does not need to be running temporarily. Although these two modes are consistent in helping users save the status of their current work in progress, there are still many subtleties between them.
Sleep mode:
1. The data in the memory can be properly retained, allowing the computer to be restarted It can then quickly return to the original running state and operation.
2. After entering the sleep state, the system's power consumption will gradually drop to a lower level. However, a power supply is still required to ensure that the data in the memory is protected.
3. In the event of an unexpected power outage, the system can quickly recover and continue normal operation by reading data from the memory.
4. Sleep mode has obvious advantages in short-term and more common usage scenarios, such as short breaks or short intervals between meetings.
Hibernation mode:
1. The tasks being executed and related environment settings will be converted into specific hibernation file forms, which are often stored in important directories on the system disk.
2. In this state, the system will be completely shut down to reduce the demand for power.
3. When the system is turned on and in sleep mode, the system will not refresh the memory repeatedly, thus improving the energy saving effect.
4. Hibernation mode is especially suitable for long-term deactivation of the computer, such as shutting down at night or during a business trip, which helps save a lot of resources.
5. The speed of recovery from hibernation is relatively slow, because the entire hibernation file needs to be loaded from the hard disk first, and then the memory state recovery operation is performed.
