When a computer resumes from hibernate mode, it reads the saved settings from the

Explanation:

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.
