NOTE: DC-AC inverter is used to generate very high AC voltage, then support to LCD CCFT backlight user, 
and is also responsible for the control of LCD brightness.  Avoid touching the DC-AC inverter area while 
the system unit is turned on. 
NOTE: There is an EEPROM in the inverter, which stores its supported LCD type and ID code.  If you replace 
a new inverter or replace the LCD with a different brand, use Inverter ID utility to update the ID 
information. DC-AC LCD Inverter

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).
Navigating the BIOS Utility
There are six menu options:  System Information, Basic System Settings, Startup Configuration, System 
Security and Loading Default Settings.
To enter a menu, highlight the item using the 
w / y keys, then press e.
Within a menu, navigate through the BIOS Utility by following these instructions:
TPress the w / y keys to move between the parameters.
TPress the z / x keys to change the value of a parameter.
TPress the | key while you are in any of the menu options to return to the main menu.
NOTE: You can change the value of a parameter if it is enclosed in square brackets.  Navigation keys are 
shown at the bottom of the screen.
