Explanation

You should use Hibernate mode. Hibernate mode is a low power state, which saves all data and open programs to the hard disk and the laptop shuts down. Since it shuts down that saves power, however, it takes significantly more time to return to an active state. What is hibernate mode? Hibernate mode is a power saving feature for computers. In hibernate mode, the current state of a computer is saved to the hard disk, and the computer shuts down. A user will have to power on the computer to restore the previous settings. When a computer resumes from hibernate mode, it reads the saved settings from the disk and restores the system state as it was before it entered hibernate mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or APM-enabled, users will have to enter hibernate mode manually. Users cannot set the computer to automatically hibernate after a certain time. With ACPI-enabled and APM-enabled computers, users are able to set hibernate mode automatically. Answer option C is incorrect. Simply shutting down won't save any files or settings. And that may cause serious problems. Answer options B and A are incorrect. These are low power modes that do not completely shut down. This means that power is still going and thus it is not saving power as much as hibernate. What is sleep mode? Sleep mode is the state of a computer where it requires a small amount of power needed to keep available data in active memory. When a user presses a key on the keyboard, the computer awakes from sleep mode. The memory data is also written to a file and saved in the hard disk. If the computer is not awakened after fifteen minutes, the operating system puts the computer in hibernate mode, cuts the power, and discards the data in RAM. What is standby mode? The standby mode is a power saving feature for computers. In this mode, a computer does not shut down completely. The computer goes to low power state and, as a result, it consumes less power. When the computer resumes from the standby mode, full power is restored to its devices. During the standby mode, if the power supply is disconnected or interrupted, data might be lost. The standby mode is available automatically on ACPI-enabled or APM-enabled computers. Users do not need to enable this mode manually. This mode is not available in non-ACPI and non-APM based computers. ernate_and_Stand_By/
