Hibernation mode

In hibernation mode, 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 mode, 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 mode, perform that action:

–Closing the lid.

–Pressing the power button.

For model U300s, to put the computer into the hibernation mode, click the Start icon and select Sleep. The computer will enter the hibernation mode after it remains in the sleep mode for 75 minutes.

Also, the computer goes into hibernation mode 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 mode 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.
