Chapter 1 29
Hibernation Mode
In Hibernation mode, all power shuts off (the computer does not consume
any power). The computer saves all system information onto the hard disk
before it enters Hibernation mode. Once you turn on the power, the computer
restores this information and resumes where you left off upon leaving
Hibernation mode.
There is one necessary condition for the computer to enter Hibernation
mode:
The Hibernation file created by PhDISK must be present and valid.
In this situation, there are four ways to enter Hibernation mode:
Pressing the Hibernation hot key Fn-F4
Allowing the waiting time specified by the S2D Time-out value to elapse
without any system activity
When a battery low condition occurs and the Battery Low Suspend
parameter in Setup is set to [ENABLED].
Invoked by the operating system power-saving modes
Note: If the computer beeps but does not enter Hibernation mode after
pressing the Hibernation hot key, it means the operating system
will not allow the computer to enter the power-saving mode.
To exit Hibernation mode, press the power switch. The computer also
resumes from Hibernation mode if the resume timer is set and matched. The
computer also resumes via the network if the Wake on LAN Access
parameter is enabled.
Warning: Do not change any devices (such as add memory or swap
hard disks) when the computer is in Hibernation mode.
Sleep Mode (ACPI)
If ACPI is installed, all power management functions are handled by the
Windows 98 operating system. In this set-up, you do not need to set time-out
values for devices before they enter a power-saving mode.
Sleep mode may be one of three computer power-saving modes: Standby,
Hibernation or power off. Windows 98 automatically determines which of
these modes to enter in.
To enter Sleep mode under ACPI:
Pressing the Sleep hot key Fn-F4
Allowing idle times for devices and the computer determined by
Windows 98 elapses
Exiting sleep mode depends on which power-saving mode the computer is
currently in.
