Blinks when a battery-low condition occurs. Chapter 1 2 Sleep Lights when the computer enters Standby mode and blinks when it enters into or resumes from hibernation mode.
Lock Keys The keyboard has three lock keys which you can toggle on and off. 12 Lock Key Description Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase. Num Lock (Fn-F11) When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. a better solution would be to connect an external keypad.
Embedded Numeric Keypad The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols are not printed on the keys. Desired Access Number keys on embedded keypad Cursor-control keys on embedded keypad Main keyboard keys Num Lock On Num Lock Off Type numbers in a normal manner.

Chapter 2 System Utilities BIOS Setup Utility The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/ Output System). Your computer is already properly configured and optimized, and you do not need to run this utility. However, if you encounter configuration problems, you may need to run Setup. Please also refer to Chapter 4 Troubleshooting when problem arises. To activate the BIOS Utility, press m during POST (while the TravelMate logo is being displayed).
System Information The System Information screen displays a summary of your computer hardware information.
Basic System Settings The Basic System Settings screen allows you to set the system date and time. Basic System Settings Date ----------------------------------Time ----------------------------------- Page 1/1 [Mon Aug 28, 2001] [20:39:33] ↑↓ = Move highlight bar, ←→ = Change setting, F1 = Help The following table describes the parameters in this screen. Parameter Description Format Date Sets the system date. DDD MMM DD, YYYY (day-of-the-week month day, year) Time Sets the system time.
Startup Configuration The Startup Configuration screen contains parameter values that define how your computer behaves on system startup. The following table describes the parameters in this screen. Settings in boldface are the default and suggested parameter settings.
The following table describes the parameters in this screen. Settings in boldface are the default and suggested parameter settings . Parameter Boot Display Description Sets the display device on boot-up. Options Both or Auto When set to Auto, the computer automatically determines the display device when the computer starts up. If an external display device (e.g., monitor) is connected, it becomes the boot display; otherwise, the computer’s display screen is the boot display.
Onboard Device Configuration The parameters in this screen are for advanced users only. You do not need to change the values in this screen because these values are already optimized. The Onboard Device Configuration screen assigns resources to basic computer communication hardware.
System Security The System Security screen contains parameters that help safeguard and protect your computer from unauthorized use.
Setting a Password Follow these steps: 1. Use the cursor up/down keys to highlight a Password parameter (Setup, Power-on or Hard Disk) and press the z / x key. The password box appears: 2. Type a password. The password may consist of up to eight characters (A-Z, a-z, 0-9). IMPORTANT:Be very careful when typing your password because the characters do not appear on the screen. 3. Press e. Retype the password to verify your first entry and press e. 4.
You have three chances to enter a password. If you successfully entered the password, the system starts Windows. If you fail to enter the password correctly after three tries, the system hangs. To change a password, follow the same steps used to set a password. To remove a password, follow the same steps used to set a password, except type nothing in the password boxes. Load Default Settings If you want to restore all parameter settings to their default values, select this menu item and press e.
BIOS Flash Utility The BIOS flash memory update is required for the following conditions: ! New versions of system programs ! New features or options Use the AFlash utility to update the system BIOS flash ROM. NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use AFlash. NOTE: This program contains a readme.txt file. This readme.txt file will introduce on how to use AFlash utility.

Chapter 4 Troubleshooting Use the following procedure as a guide for computer problems. NOTE: The diagnostic tests are intended to test only Acer products. Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses. 1. Obtain the failing symptoms in as much detail as possible. 2. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. 3.
System Check Procedures External Diskette Drive Check Do the following to isolate the problem to a controller, driver, or diskette. A write-enabled, diagnostic diskette is required. NOTE: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device. See “System Diagnostic Diskette” on page 38 for details. 1.
Keyboard or Auxiliary Input Device Check Remove the external keyboard if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated in the connector on the system board. If the keyboard cable connection is correct, run the Keyboard Test. See “System Diagnostic Diskette” on page 38 for details.
Check the Power Adapter Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power adapter cable. See the following figure Pin 1: +19 to +20.5V Pin 2: 0V, Ground 1. If the voltage is not correct, replace the power adapter. 2. If the voltage is within the range, do the following: ! Replace the System board. ! If the problem is not corrected, see “Undetermined Problems” on page 78. If the voltage is not correct, go to the next step.
Check the Battery Pack To check the battery pack, do the following: From Software: 1. Check out the Power Management in control Panel 2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. 3. Repeat the steps 1 and 2, for both battery and adapter. 4. This helps you identify first the problem is on recharging or discharging. From Hardware: 1. Power off the computer. 2.
Power-On Self-Test (POST) Error Message The POST error message index lists the error message and their possible causes. The most likely cause is listed first. NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also help you determine the next possible FRU to be replaced when servicing a computer.

Action in Sequence Enter BIOS Setup Utility to execute “Load Default Settings”, then reboot system. Reconnect hard disk/CD-ROM/diskette drives. External display does not work correctly.
Intermittent Problems Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. When analyzing an intermittent problem, do the following: 1. Run the advanced diagnostic test for the system board in loop mode at least 10 times. 2. If no error is detected, do not replace any FRU. 3.
Undetermined Problems The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU). NOTE: Verify that all attached devices are supported by the computer. NOTE: Verify that the power supply being used at the time of the failure is operating correctly. (See “Power System Check” on page 67): 78 1.
