6.2.4 Reset Switch
Function: Restarts the system to cold boot.
Use: Press the button to restart the system. This forces a restart under all
conditions. Don’t use the Reset button if you can shut the system down
from within the Operating System.
6.2.5 Note On Reset & Rebooting:
You should always restart or shut down the system by using the OS com-
mand for this. This procedure allows the OS to shut down properly, mini-
mizing the possibility of hard disk drive problems or data loss. If the
system crashes or ‘hangs’, you may have to restart the system
at the hardware level. There are two hardware reboot options, a keyboard
command and the Reset button.
You can affect a “warm” reboot with a key command if the OS supports
it. For example, all versions of Microsoft Windows support restarting the
computer with the Ctrl-Alt-Del (Delete) command. You can try this com-
mand first if it is supported. Otherwise, you will need to use the Reset
button.
6.2.6 Suspend Button
Function: Toggles system in and out of Suspend mode.
Use: Press the button to cause the system to enter or resume from Sus-
pend mode. Note: The front panel feature connector supports a system
Suspend button (the ACPI connector) but not all system housings have
this button. The same function can be performed at the Operating System
level if the OS supports the feature.
6.2.7 Indicator LEDs
The motherboard front panel features connector supports three-system
status indicator LEDs:
1. Power Status LED Indicator Lights when the system is turned on.
2. System Hard Disk Drive Activity LED Indicator Flashes during
hard disk drive access.
3. Power Conservation Mode LED Indicator Lights to indicate the
system is in a Suspend state power conservation mode. Most sys-
tem housings will have all of these LEDs mounted in the housing’s
front panel.
USB 2.0:
USB 2.0 support is provided for Windows 2000 and Windows XP. Under
other operating systems the USB ports will function as USB 1.1 ports.
