1.2 System Memory Options
Depending on the computer model, the main memory subsystem supports
a minimum of 32 or 64 megabytes of Synchronous SDRAM, expandable
to 160 or 192 megabytes. The minimum standard Synchronous SDRAM
is integrated on the system board. The upgrade SDRAM is accomplished
with memory expansion boards that are available on 128-, 64-, and 32-
megabytes.
The memory expansion slot is located underneath the fan/CPU cover.
Refer to Chapter 5, “Removal and Replacement Procedures,” for
information on installing and removing memory expansion boards.
System memory can be upgraded as shown in Table 1-3.

1.3 Power Management Functions
Power Management functions of the computer are designed to conserve
power. All Power Management functions can be configured from the
Setup Configuration Utility (SCU), described later in this chapter.
Automatic Power Management
Automatic Power Management operates at two levels as described in the
following paragraphs.
Local Power Management
Local Power Management controls computer subsystems. When a
subsystem is inactive for a period of time, it is automatically shut down
or slowed to reduce power consumption. The subsystem returns to an
active state when it is accessed.
Subsystems under Power Management include:
■ Hard disk drive
■ Diskette drive
■ CD-ROM drive
■ LCD display panel
Global Power Management
Global Power Management automatically puts the computer into Suspend
mode when the computer is inactive for a period of time. The computer
wakes up whenever activity resumes.
The time-out settings for Suspend mode are set up in the SCU program.
The computer uses Suspend-to-RAM (Standby) or Suspend-to-Disk
(Hibernation) depending on the Suspend Data To setting in the SCU
program.
Manual Power Management
Suspend mode can be initiated at any time in one of two ways:
■ By pressing Fn + F12.
■ By closing the top cover, if the Cover Close option is set to Suspend
in the SCU program.

Suspend-to-Disk (Hibernation)
When the computer suspends to disk, the system preserves all the running
application programs as a file in a Suspend-to-Disk partition on the hard
disk. The computer then turns off automatically. When the computer is
powered on, the system reads the file from the Suspend-to-Disk partition
back into memory, returning the computer to the state it was in before it
was suspended.
If there is no Suspend-to-Disk partition on the hard disk, use the
HIBERNAT utility to create the partition, in order to be able to use the
Suspend-to-Disk feature.
Suspend-to-RAM (Standby)
When the computer suspends to RAM, several subsystems enter standby
or power-off mode to conserve power. The system wakes up when any
key is pressed. Resume Timer and Ring Resume options also wake the
system from Suspend-to-RAM.
1.4 Setup Configuration Utility (SCU)
The system comes with a Setup Configuration Utility (SCU). This utility
configures BIOS settings via menu-driven utilities. Settings are stored in
the CMOS RAM.
The SCU must be used when:
■ An error message indicates that the SCU should be run.
■ Factory default settings need to be restored (after BIOS upgrades).
■ Specific settings must be modified.
Starting the SCU
The SCU resides on the system ROM chip. Start the utility by pressing
F10 during initial power up.

Main SCU Screen
The SCU main screen is divided into three areas:
Menu area –lists the available menu titles, across the top of the screen.
Each menu title provides a pull-down menu of item settings.
Display area –displays current system settings. This section also
displays submenus for items that provide multiple options.
Information and navigation area –provides keyboard/mouse
instructions for moving around and making decisions.
You can select items using either the keyboard or theTouchPad/mouse.
