Inrush current The maximum inrush current will be less than 150Ap-p when the adapter is 
connected to 115Vac(60Hz) and 230Vac(50Hz) respectively.
Efficiency  It should provide an efficiency of 83% minimum, when measured at maximum 
load under 115V(60Hz).
Output Ratings

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...

Main
The Main screen displays a summary of your computer hardware information, and also includes basic setup 
parameters. It allows the user to specify standard IBM PC AT system parameters.
NOTE: The screen above is for reference only. Actual values may differ. 

Chapter 231
The table below describes the parameters in this screen. Settings in boldface are the default and suggested 
parameter settings.
NOTE: The sub-items under each device will not be shown if the device control is set to disable or auto. This is 
because the user is not allowed to control the settings in these cases.
