Mini Tower System

Power Switch

The power switch is a DC on/off control circuit that is connected to the soft power push-button switch through the system PWA. When used with a power supply that supports remote power on/off, the system board can be turned off from either of two sources: the front-panel "Remote ON/OFF" switch or a "soft off" signal (coming from the super I/O controller) that can be controlled by an operating system.
In "soft off," an APM command issued to the system BIOS causes the power supply to turn off via the "PS ON" control signal on the power connector. For example, Windows� 95 issues this APM command when you click on the Shutdown icon. Power can be restored via a front-panel power button connected to a front-panel header.

Power Indicator

The power indicator lights up when the system is on.

Reset Button

Pressing the reset button initiates a hardware reset. To avoid possible data or file structure corruption, use the reset button only when the system cannot be rebooted with the <Ctrl><Alt><Del> key combination, and perform an orderly shutdown of the operating system.

Hard-Disk Drive Access Indicator

The hard-disk drive access indicator lights up when the hard-disk drive is being accessed.

Diskette-Drive Access Indicator

The diskette-drive access indicator lights up when the diskette drive is being accessed.
