Related service information 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 from the docking station 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 APM operating system and have set the mode to Power switch mode [Hibernation], turn off the power switch. 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 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. v If you are using the APM operating system and have set the mode to Hibernate when battery becomes low, and the battery charge becomes critically low. 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. General descriptions 35

conditions:
v
If
