Note: DC-AC inverter is used to generate very high AC voltage, then
support to LCD CCFT backlight user, and is also responsible for
the control of LCD brightness. Avoid touching the DC-AC inverter
area while the system unit is turned on.
Note: There is an EEPROM in the inverter, which stores its supported
LCD type and ID code. If you replace a new inverter or replace
the LCD with one of a different brand, use Inverter ID utility to
update the ID information. LCD Inverter

38 System Introductions 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, floppy 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 handles all power-saving chores for your computer. Note: Power management (APM or ACPI) greatly prolongs your battery life. See “Advanced Power Management” on page 41 and “Advanced Configuration and Power Interface” on page 41 for more information. 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 Turn Off Display 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 Turn Off Hard Disk 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 39 Standby Mode The computer consumes very low power in Standby mode. Data remains intact in the system memory until the battery is drained. There are six ways to enter Standby mode: Pressing the Standby hot key Fn-F3 If the waiting time specified by the System Standby value or the operating system elapses 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 When the advanced power button function(s) in the Notebook Manager program is/are set to Standby mode Invoked by the operating system power-saving modes 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: 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: Press any key Move the active pointing device (internal or external PS/2) Have the resume timer set and let it be matched Open the display cover Experience an incoming PC card modem event 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.
40 System Introductions There is one necessary conditions for the computer to enter Hibernation mode: The Hibernation file created by Sleep Manager must be present and valid. In this situation, there are five ways to enter Hibernation mode: Pressing the Hibernation hot key Fn-F4 If the waiting time specified by the System Hibernation value elapses without any system activity If a battery low condition occurs and the Sleep Upon Battery-low parameter in the BIOS Utility is enabled When the advanced power button function(s) in the Notebook Manager program is/are set to Hibernation mode 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. 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 operating system. In this set-up, you do not need to set timeout values for devices before they enter a power saving mode. For more information on ACPI, see “Advanced Configuration and Power Interface” on page 41. Sleep mode may be one of three computer power saving modes: standby, hibernation or power off. Windows automatically determines which of these modes to enter in. To enter Sleep mode under ACPI: Press the Sleep hot key Fn-F4. 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.
