Chapter 1 System Introduction This computer was designed with the user in mind. Here are just a few of its many features: Performance ❑ Intel Pentium® processor with MMX™ technology ❑ 512-KB, 64-bit main memory and external (L2) cache memory ❑ Large LCD display and PCI local bus video with 128-bit graphics acceleration ❑ Internal CD-ROM drive ❑ Internal 3.
from peripherals ❑ Upgradeable memory and hard disk Display The large graphics display offers excellent viewing, excellent display quality and high performance desktop graphics. The computer supports two different display configurations — High Performance Addressing (HPA) or Thin-Film Transistor (TFT). Video Performance The PCI local bus video with 128-bit graphics acceleration and 2MB Extended Data Out (EDO) video RAM boosts video performance.
Basic Operation Indicators The computer has six easy-to-read status indicators (LEDs) under the display screen. The Power and Standby indicators are visible even when you close the display cover so you can see the status of the computer while the cover is closed. # 1 Icon Function Power Description Lights when the computer is on. Blinks when a battery-low condition occurs. 2 Standby Lights when the computer enters Standby mode.
Keyboard The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows 98 keys and twelve function keys. Special Keys Lock Keys The keyboard has three lock keys which you can toggle on and off. 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 /).
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 Num Lock On Num Lock Off Number keys on embedded keypad Type numbers in a normal manner. Cursor-control keys on embedded keypad Hold Shift while using cursor-control keys. Hold Fn while using cursorcontrol keys.
Windows 98 Keys The keyboard has two keys that perform Windows 98-specific functions. Key Windows logo key Description Start button. Combinations with this key performs special functions. Below are a few examples: + Tab (Activate next Taskbar button) + E (Explore My Computer) + F (Find Document) + M (Minimize All) Shift + + M (Undo Minimize All) + R (Display Run dialog box) Application key 14 Opens the application’s context menu (same as rightclick).
Hot Keys The computer employs hot keys or key combinations to access most of the computer’s controls like screen contrast and brightness, volume output and the BIOS setup utility. Hot Key Icon Function Description Fn-F1 Hot key help Displays a list of the hotkeys and their functions. Fn-F2 Setup Accesses the notebook configuration utility. . Fn-F3 Standby Puts the computer in Standby mode. Press any key to return. See “System Standby Mode” on page 30 to learn more about Standby mode.
Hot Key Fn-F7 Icon Function Touchpad on/off Description Turns the internal touchpad on and off. When you connect an external PS/2 mouse, the computer automatically disables the touchpad. Fn-F8 Speaker on/off Turns the speakers on and off; mutes the sound. Fn-↑ Contrast up Increases the screen contrast (available only for models with HPA displays). Fn-↓ Contrast down Decreases the screen contrast (available only for models with HPA displays). Fn-→ Brightness up Increases the screen brightness.

Chapter 4 Troubleshooting Use the following procedure as a guide for computer problems. Note: The diagnostic tests are intended to test only Acer products. NonAcer 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 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 “Running the Diagnostics” for details. 1.
2. Replace the CD-ROM drive. 3. Replace the system board. 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 “Running the Diagnostics” for details.
2. Connect the power adapter and check that power is supplied. 3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by the battery pack. If you suspect a power problem, see the appropriate power supply check in the following list: ❑ “Check the Power Adapter” on page 76 ❑ “Check the Battery Pack” on page 76 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.
2. Remove the battery pack and measure the voltage between battery terminals 2(+) and 7(ground). See the following figure 3. If the voltage is still less than 8.0 Vdc after recharging, replace the battery. To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator does not light up, remove the battery pack and let it return to room temperature.
Error Symptom-to-FRU Index The symptom-to-FRU index lists the symptoms and errors 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.
