Also, in either of the following events, the computer
automatically returns from standby mode and resumes
operation:
v The ring indicator (RI) is signaled by a serial device or a

Hibernation mode

In hibernation mode, the following occurs:
v The system status, RAM, VRAM, and setup data are
stored on the hard disk.
v The system is powered off.
Note: If the computer enters the hibernation mode while it
is docked to the docking station, do not undock it
before resuming normal operation. If you do undock
it and then try to resume normal operation, you will
get an error message, and you will have to restart
the system.
To cause the computer to enter hibernation mode, do any
of the following:
v Press the Fn+F12 keys.
v 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.
– Pressing Fn+F4 keys.
Also, the computer goes into hibernation mode
automatically in either of the following conditions:
v If a "hibernation time" has been set on the timer, and if
the user does not do any operation with the keyboard,
the TrackPoint, the hard disk drive, the parallel
connector, or the diskette drive within that time.
v 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.
