Display
The large graphics display offers excellent viewing, display quality and desktop performance graphics. The computer supports a Thin-Film Transistor (TFT) liquid crystal display (LCD) displaying 16-bit hi-color at 1024x768 Extended Graphics Array (XGA) resolution.
Video Performance
PCI local bus video with industry-leading 256-bit graphics acceleration and high-speed 2.5MB Synchronous Graphics Random Access Memory (SGRAM) boost video performance.
Simultaneous Display
The computer's large display and multimedia capabilities are great for giving presentations. If you prefer, you can also connect an external monitor when giving presentations. This computer supports simultaneous LCD and CRT display. Simultaneous display allows you to control the presentation from your computer and at the same time face your audience. With the built-in Svideo output jack, you can even connect other output display devices such as LCD projection panels for large-audience presentations.
Dual Display
The computer's unique graphics chip takes advantage of Windows 98's multidisplay capability, allowing you to extend your desktop to an external display device, such as an external monitor or projector. With this feature enabled, you can move program windows to/from the computer LCD and the external monitor.
Power Management
The power management system incorporates an "automatic LCD dim" feature that automatically decides the best settings for your display and at the same time conserves power.

System Specifications
Opening and Closing the Display
To open the display, slide the display cover latch to the left and lift up the cover. Then tilt it to a comfortable viewing position. The computer employs a microswitch that turns off the display (and enters standby mode) to conserve power when you close the display cover, and turns it back on when you open the display cover. Note: If an external monitor is connected, the computer turns off the display (but does not enter standby mode) when you close the display cover. To close the display cover, fold it down gently until the display cover latch clicks into place. Warning: To avoid damaging the display, do not slam it when you close it. Also, do not place any object on top of the computer when the display is closed.

System Specifications
Power Management
This computer has a built-in power management unit that monitors system activity. System activity refers to any activity involving one or more of the following devices: keyboard, mouse, drive, hard disk, peripherals connected to the serial and parallel ports, and video memory. If no activity is detected for a period of time (called an inactivity time-out), the computer stops some or all of these devices in order to conserve energy. This computer employs a power management scheme that supports APM (Advanced Power Management) or ACPI (Advanced Configuration and Power Interface) which allows for maximum power conservation and maximum performance at the same time. If your computer is set for APM, you can set time-out values for your computer's devices before power-saving methods are applied to these devices. If your computer is set for ACPI, Windows 98 handles all powersaving chores for your computer. Note: Power management (APM or ACPI) greatly prolongs your battery life.
Power Management Modes
Display Standby Mode Screen activity is determined by the keyboard, the built-in touchpad, and an external PS/2 pointing device. If these devices are idle for the period specified by the LCD backlight Time-out value, the display shuts off until you press a key or move the touchpad or external mouse. "Automatic Dim" Feature The computer has a unique "automatic dim" power-saving feature. When the computer is using AC power and you disconnect the AC adapter from the computer, it automatically dims the LCD backlight to save power. If you reconnect AC power to the computer, it automatically adjusts the LCD backlight to a brighter level. Hard Disk Standby Mode The hard disk enters Standby mode when there are no disk read/write operations within the period of time specified by the Hard Disk Time-out value. In this state, the power supplied to the hard disk is reduced to a minimum. The hard disk returns to normal once the computer accesses it.
Chapter 1
27
Standby Mode The computer consumes very low power in Standby mode. Data remain intact in the system memory until the battery is drained. There are four ways to enter Standby mode:
6 6 6 6
Pressing the Standby hot key Fn-F3 Allowing the waiting time specified by the Standby Time-out value or the operating system to elapse without any system activity Closing the display cover When the computer is about to enter Hibernation mode (e.g., during a battery low condition), but the Hibernation file is invalid or not present Note: If the computer beeps but does not enter Standby mode after pressing the Standby hot key, it means the operating system will not allow the computer to enter the power-saving mode.
The following signals indicate that the computer is in Standby mode:
6 6
The buzzer beeps The Standby indicator lights Warning: Unstored data is lost when you turn off the computer power in Standby mode or when the battery is drained.
To leave Standby mode and return to normal mode:
6 6 6 6 6
Press any key Move the active pointing device (internal or external, PS/2 or serial) Have the resume timer set and let it be matched Open the display cover Experience an incoming PC card modem event
28
System Specifications
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:
6 6 6 6 6
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:
6 6
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. Chapter 1 29
Advanced Power Management
This computer supports the APM standard designed to further reduce power consumption. APM is a power-management approach defined jointly by Microsoft and Intel. An increasing number of software packages support APM to take advantage of its power-saving features and to allow greater system availability without degrading performance. For more information about APM under Windows 98, refer to your Windows 98 user's manual.
Advanced Configuration and Power Interface
Advanced Configuration and Power Interface (ACPI) is a power management specification jointly developed by Intel, Microsoft, and Toshiba. ACPI enables Windows 98 to control the amount of power given to each device attached to the computer. With ACPI, Windows 98 can turn off peripheral devices when they are not in use, thereby saving power.

PhDISK
The PhDISK utility allows your computer to enter Hibernation mode. Before entering Hibernation mode, your computer saves all necessary information into a file or partition created by PhDISK, then shuts off power to all system components. On the next start-up, the computer reloads the information from the PhDISK file or partition and resumes from where you left off. Note: By default, this utility program is automatically loaded and set up on your computer, so you do not need to run it by yourself. You only need to run this program if you upgrade your memory. You can find PhDISK in the \windows\command\ directory.
Syntax
PHDISK [options] where options:
6 6 6 6
/CREATE (/FILE or /PARTITION) creates the hibernation file or partition /DELETE (/FILE or /PARTITION) deletes the hibernation file or partition /INFO displays information on the hibernation file or partition /REFORMAT PARTITION reformats the existing hibernation file or partition
Caution: The Hibernation file is a hidden file named SAVE2DSK.BIN; DO NOT delete or alter this file in any way except by using the PhDISK utility. Improper deletion or alteration of this file could cause you to lose all access to your computer.
