5-14 BIOS Functions Rev. I
Suspend Mode Select the time it takes for the system to enter Suspend Mode by BIOS from option settings.
The default setting is Disabled.
Be careful not to set the time value too small as the system may frequently switch between Full-
On Mode and Suspend Mode.
Setting for OS
DOS: Because DOS does not have a suspend timer, use this setting to set the time to enter the
Suspend mode.
Windows NT: Because entering the Suspend mode on Windows NT creates a delay in the timer
of the operating system, be sure that the suspend timer setting is functioning properly.
Windows 98/2000/XP: For Windows 98 and later operating systems, set the suspend timer from
the system. The BIOS suspend timer is ignored regardless of the setting.
HDD Power
Down To have the HDD enter the Power Down mode after a certain period of inactivity, choose the
time of inactivity in the BIOS from the option setting.
The default setting is “Disabled”.
This function was added in Ver.2.13.00.
Versions 2.12 and before do not have this function.

BTTN Sets the function of the Power Button (switch) when pressed.
The default setting is Disabled. The basic operations of BIOS are as follows.
Instant-Off:
The power supply is turned off immediately when the Power button is
pressed.
Delay 4 Sec.: If the Power button is pressed and held for less than 4 seconds:
1) Shift to the Suspend mode if this operation is performed in the Full-On
mode.
2) Shift to the Full-On mode if this operation is performed in the Suspend
mode.
If the Power button is pressed and held for at least 4 seconds:
1) Shift to the Suspend mode once, and the power supply is forcefully turned
off after 4 seconds.

2) Recover to the Full-On mode when the Power button is pressed in the
Suspend mode.
3) If the Power button is pressed and held for at least 4 seconds, the power
supply is forcefully turned off.
If the power is forcibly turned off by continuously pressing the power button for at least four
seconds when "Delay 4 Sec." is set, the Wake On LAN (WOL) function cannot be used next time
the power is turned on. In this case, restart the system by using the power button and execute
normal power off by using the OS. The WOL function can then be used at next startup.
