In certain circumstances, the computer goes into sleep mode automatically:

To resume the computer from sleep mode, press the power button.
Also, in either of the following events, the computer automatically returns from sleep mode and resumes
operation:
• The ring indicator (RI) is signaled by a serial device or a PC Card device.
• The time set on the resume timer elapses.
Note:
The computer does not accept any input immediately after it enters sleep mode. Wait a few
seconds before taking any action to reenter operation mode.
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.
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.
If you have defined one of the following actions as the event that causes the system to go into hibernation
mode, perform that action.
