Hibernation state
In hibernation state, the following occurs:
• The system status, RAM, VRAM, and setup data are stored on the hard disk.
• The system is powered off.
To cause the computer to enter hibernation state, follow the steps below:
• If you are using the ACPI operating system and have defined one of the
following actions as the event that causes the system to go into hibernation
state, perform that action:
– Closing the lid.
– Pressing the power button.
Also, the computer goes into hibernation state automatically in either of the
following conditions:
• If a “hibernation time” has been set on the timer, and if the user does not do
any operation with the keyboard, the hard disk drive, the parallel connector,
or the diskette drive within that time.
• If the timer conditions are satisfied in suspend mode.
When the power is turned on, the computer returns from hibernation state and
resumes operation. The hibernation file in the boot record on the hard disk drive
is read, and system status is restored from the hard disk drive.
Note:
When the SSD and HDD are being configured, the computer will enter
hibernation state automatically.
