Buttons Power Button Under ACPI, the power button action is under the control of the operation system. • The following is a table of the state transitions in ACPI mode. Initial Final Comments Off On Does a normal reboot. Prompts for password if required. Standby On Restores device states from RAM. Prompts for password if required. Hibernate On Restores RAM and device states from disk. Prompts for password if required. On Standby, Hibernate( default) or Off . Action depends on OS setting.
Multi Boot The notebook can support Multi Boot for selecting the boot sequence of hard disk, floppy, CD ROM, Network Boot in Setup. It identifies all IPL (Initial Program Load) devices in the system and attempts to boot them in the order specified in Setup. Quiet Boot Quiet Boot replaces the customary technical messages during POST with a more visually pleasing and comfortable display (OEM Logo screen).
Security Features Security features to be supported are passwords, electronic serial number, PC identification string. The Electronic Serial Number provides a unique way of identifying an individual notebook. PC Identification strings allow the user or administrator to personalize the notebook for asset tracking or identification if it is lost. The Passwords, Serial Number, and PC Identification strings are to be stored in EEPROM. 2 Level Passwords The notebook supports two levels of password protection.
• The numbers 0 to 9. • The letters A to Z (not case sensitive). The password is stored as scan codes. Electronic Serial Number The electronic serial number is a ten (10) byte string which matches the manufacturing serial number on the bottom of the notebook. The BIOS must display the electronic serial number in the boot screen and in Setup. The format of the line should be Serial Number: SSSSSSSSSS where SSSSSSSSSS is the electronic serial number.
reduced in an effort to reduce heat generation. The second type is active cooling where a fan is turned on to cool the system. In non-ACPI mode(Legacy Mode), the thermal management is achieved by controlling the fan depend on the temperature. Besides turning the fan on and off. The system may also be shut off whenever the temperature can’t be reduced even the fan are spinning in the full speed. The system will be turned off immediately when it’s over-heating (over 85°C).
Device Power Management The device specific power management supported by this notebook includes the CPU and the hard disk. CPU power management • ACPI mode The operating system detects when the system is idle and places the CPU in one of the 3 CPU low power states (C1, C2 or C3) depending on how much latency it believes the system can afford. The C1 state is simply the CPU halt instruction. The C2 state is the CPU stop grant state. The C3 state is the CPU stop clock state.
Critical low battery - - - - Field ‘Process Required’ identifies that further process for the occurred events must be processed during wake up or resume procedure. *1: Hot keys are not wake up source of standby, suspend to RAM and Hibernate states. *2: Activity of the USB device is dependent on the driver support. Power Button The power button will wake the system from any low power state as described in the Power Button section.
EEPROM There is one EEPROM which is used to store many important system and user data in the notebook The size of the EEPROM is 2K bytes. Password Protection Password and Security support will be implemented in this model. See the PhoenixBIOS 4.0 User Manual for sample screen and the description of Password and Security support. VGA Support This section describes the expected behavior when a video monitor is connected to the VGA port on the notebook or port replicator.
customer may choose to manually install it. The Synaptics TouchPad driver should only be installed after first selecting Touch pad only in BIOS Setup. • Hold down center button of external PS/2 mouse: While holding down the center button of an external mouse, move the mouse. This will cause the window to move. If the center button is not held down, all pointing devices function normally. • Use TouchPad: The TouchPad is locked in as the Scrolling or Magnifying Glass device.

This would be filled in at boot time. Please see section 5.4.
System Setup Invoking setup The setup function can only be invoked by pressing F2 when ″ Press to enter Setup″ message is prompted on the bottom of screen during POST. The setup uses a menu driven interface to allow the user to configure their system. The features are divided into 6 parts as follows: Main Allows the user to specify standard IBM PC AT system parameters. System Devices Provides advanced settings of the system. Security Provides security settings of the system.
The Floppy Drive status is auto detected by system. 1.44MB, 3 1/2 “ If there exists floppy drive. Not installed If there is no floppy drive. Internal Hard Disk The hard disk types and capacity are auto detected and set by the system. If there is no hard disk present or unknown type, ″None″ should be shown on this field, otherwise the capacity must be shown. ATAPI Device The CD-ROM, DVD-ROM or CD-RW are auto detected and set by the system.

ACY25 14.1” & 15” INVERTER SPECIFICATION General Description There are two control signals that come from system to control lamp brightness. One signal is named DAC_BRIG, which limits current to meet LCD lamp current specification. Another one is named PWM, which adjusts lamp brightness. This inverter brightness is adjusted by PWM burst mode. The PWM burst mode is that turning on and off the lamp at a rate of 150Hz. The effective brightness is a function of the duty cycle.

Chapter 5: Disassembly General This chapter provides detailed directions for disassembling the computer. You will require a medium size screwdriver, small screwdriver and a 6mm nut driver (for the helix screw nuts on the rear ports). Before starting to disassemble the computer, refer to the diagram below. This indicates which modules need to be removed to access the module needing replacement. Always start by removing the battery pack.
The example below shows which modules need to be removed before the audio board can be removed and repaired or replaced. The audio board is overlapped by the top cover, which must be removed before the audio board can be reached. The top cover is in turn overlapped by several other units (shaded gray) and these must be removed before the top cover can be reached. Always starts the disassembly process by removing the battery.
Safety Precautions Before you begin disassembly, read the following safety precautions and observe them carefully as you work. DANGER: 1. Always use the lithium ion battery pack or backup battery that is authorized by the manufacturer or compatible with the unit. Since other battery packs have different specifications, they may be incompatible with the unit, and may burst or explode. Heating or disassembling the battery pack could cause leakage of alkaline solution.
Before You Begin Look over the procedures in this section before you begin disassembling the computer. Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by removing the AC adaptor and the battery pack. 1. Do not disassemble the computer unless it is operating abnormally. 2. Use only the correct and approved tools. 3. Make sure the working environment is free from the following elements whether you are using or storing the computer.
Disassembly Procedures The computer has two basic types of cable connectors: Pressure Plate Connectors Standard Pin Connectors To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector’s plastic pressure plate and slide the cable out of the connector.
