Standby Mode
Waiting time specified by the System Standby value 
or the operating system elapses without any system 
activity.
Or
When the computer is about to enter Hibernation 
mode (e.g. during a battery-low condition), but the 
Hibernation file is invalid or not present.The Sleep indicator lights up

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).
Press 
m to enter setup. Press  during POST to enter multi-boot menu. In this menu, user can change 
boot device without entering BIOS SETUP Utility.
