Soft Power Connector
The Soft Power Connector is part of jumper block J1 (pins 6-8). The Trinity KT uses
the chipset for power management, including turning on and off the system. If the
Power Button Function option in the BIOS Power Management Menu is set to On/Off
(which is the default), pressing the power button once after the BIOS has booted up
will turn the system on and off. If the Power Button Function option is set to
Suspend, pressing the power button once will wake the system or send it to Suspend
mode. In this case, you cannot turn the system off unless you shut down through the
Windows operating system or you hold the power button down for four seconds.
Hardware Reset Switch Connector Installation
The Reset switch on your cases display panel provides you with the Hardware Reset
function, which is the same as power on/off. The system will do a cold start after the
Reset button is pushed.
CMOS RTC
The Real Time Clock (RTC) circuit, which provides the date and time for the system is
integrated into the KT-133 chipset. If the external battery for the RTC is low, it will
prevent your system from POSTing, and you will not get a display. Normally the life
span of an external battery is 2 years. If yours is running low, you will need to replace
it with a new 3V lithium battery (Sony CR2032).
Flash EEPROM
The Trinity KT uses flash memory to store BIOS firmware. It can be updated as new
versions of the BIOS become available. You can upgrade your BIOS easily using the
Flash Utility (see page 55).
