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

General Description This inverter is designed for the CCFL of 550 14.1" LCD which are using on the 550 notebook. We use two signals to control the LCD brightness. One is the Enable, which turn on and turn off the birightness of LCD. The other is the PWM, which tune the brightness by modulating the duty cycle. This inverter uses open loop control circuit and meets with safety requirements. Features 1. +5V Fixed input voltage 2. Birghtness adjustment by PWM duty cycle 3. Current Limited function, meet with safety requirement Inverter Characteristics

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, System Device, 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.
