Touchpad
The built-in touchpad is a PS/2-compatible pointing device that senses movement on its surface. This means the cursor responds as you move your finger on the surface of the touchpad. The central location on the palm rest provides you optimum comfort and support.
Touchpad Basics
The following teaches you how to use the touchpad:
! !
Move your finger across the touchpad to move the cursor. Press the left (1) and right (2) buttons located on the edge of the touchpad to do selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad produces similar results.
Function Execute
Left Button Click twice quickly Click once Click and hold, then use finger to drag the cursor on the touchpad
Righ Button
Tap Tap twice (at the same speed as double-clicking the mouse button) Tap once Tap twice (at the same speed as double-clicking a mouse button) then hold finger to the touchpad on the second tap to drag the cursor
Select Drag
Access context menu
Click once
NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The 22 Chapter 1
touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response. Tapping too hard will not increase the touchpad's responsiveness.

Launch Keys
Located above the keyboard are launch keys that can used to launch applications.
NOTE: To configure the launch keys and the applications they launch..

There are two control signals that come form 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 rate of 150Hz. The effective brightness is a function of the duty cycle. Features 1. Wide range 9V to21V input voltage. 2. Birghtness adjustment by PWM duty mode.

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 (when "Press to enter Setup" message is prompted on the bottom of screen).
Navigating the BIOS Utility
There are six menu options: Main, Advanced , Security, Others, Boot and Exit. Follow these instructions:
! ! ! ! ! !
To choose a menu, use the cursor left/right keys (zx). To choose a parameter, use the cursor up/down keys ( wy). To change the value of a parameter, press p or q. A plus sign (+) indicates the item has sub-items. Press e to expand this item. Press ^ while you are in any of the menu options to go to the Exit menu. In any menu, you can load default settings by pressing t. You can also press u to save any changes made and exit the BIOS Setup Utility.
NOTE: You can change the value of a parameter if it is enclosed in square brackets. Navigation keys for a particular menu are shown on the bottom of the screen. Help for parameters are found in the Item Specific Help part of the screen. Read this carefully when making changes to parameter values.

Use the Phlash utility to update the system BIOS flash ROM. NOTE: If you do not have a crisis recovery diskette at hand, then you should create a Crisis Recovery Diskette before you use the Phlash utility. NOTE: Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash. NOTE: Please use the AC adaptor power supply when you run the Phlash utility. If the battery pack does not contain enough power to finish BIOS flash, you may not boot the system because the BIOS is not completely loaded. Fellow the steps below to run the Phlash. 1. 2. 3. Prepare a bootable diskette. Copy the Phlash utilities to the bootable diskette. Then boot the system from the bootable diskette. The Phlash utility has auto-execution function.
System Diagnostic Diskette
IMPORTANT: 1The diagnostics program we use for Aspire 1400 is not exactly the same as PQA (Product Quality Assurance), the diagnostic program we used to employ in other model. The system diagnostic utilities is provided by Acer Headquarters. You can utilize it as a basic diagnostic tool. To get this program, find it in the Aspire 1400 service CD kit. To better fit local service requirements, your regional office MAY have other diagnostic program. Please contact your regional offices or the responsible personnel/channel to provide you with further technical details. NOTE: For ASSY Function Test Procedure, please prepare the following items for system components test: PIO loopback, formatted floppy diskette, CD-DISK (Test Program), Sycard (Card Bus)x2, AC-adapter, feather (to see if the fan works), TPDL server, USB_HUP, USB_barcode scanner.

Troubleshooting
Use the following procedure as a guide for computer problems. NOTE: The diagnostic tests are intended to test this model (Aspire 1400 series). Non-Acer products, prototype cards, or modified options can give false errors and invalid system responses. 1. 2. 3. Obtain the failed symptoms in as much detail as possible. Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating the same operation. If any problem occurs, you can perform visual inspection before you fellow this chapter's instructions. You can check the following: power cords are properly connected and secured; there are no obvious shorts or opens; there are no obviously burned or heated components; all components appear normal. 4. Use the following table with the verified symptom to determine which page to go to.
Symptoms (Verified)
Go To
Power failure. (The power indicator does not go on or stay on.) POST does not complete. No beep or error codes are indicated. POST detects an error and displayed messages on screen. The diagnostic test detected an error and displayed a FRU code. Other symptoms (i.e. LCD display problems or others). Symptoms cannot be re-created (intermittent problems).
"Power System Check" on page 71. "Power-On Self-Test (POST) Error Message" on page 73 "Undetermined Problems" on page 81 "Error Message List" on page 74 "System Diagnostic Diskette" on page 48 "Power-On Self-Test (POST) Error Message" on page 73 Use the customer-reported symptoms and go to "Power-On Self-Test (POST) Error Message" on page 73 "Intermittent Problems" on page 80 "Undetermined Problems" on page 81
