2.3 POWER OFF THE PC SYSTEM
1. When ATX power supply is connected.
There are two ways to power off the system. They are “Shut Down by Power
Button” and “ Shut Down by OS”. (such as Windows® 95 and Windows® 98,
you can choose the Shut Down from the file menu and the system will be
powered off immediately ).
2. When AT power supply is connected.
You can not use the OS to shut down the PC system, you can use only the power
switch to turn the system power off.
