Powering up

ASUS A7S333 motherboard

3.1 Starting up for the first time

1. After making all the connections, replace the system case cover.

2. Be sure that all switches are off.

3. Connect the power cord to the power connector at the back of the

system chassis.

4. Connect the power cord to a power outlet that is equipped with a surge

protector.

5. Turn on the devices in the following order:

a. Monitor

b. External SCSI devices (starting with the last device on the chain)

c. System power (if you are using an ATX power supply, you need to

switch on the power supply as well as press the ATX power switch

on the front of the chassis).

6. After applying power, the power LED on the system front panel case

lights up. For ATX power supplies, the system LED lights up when you

press the ATX power switch. If your monitor complies with “green”

standards or if it has a “power standby” feature, the monitor LED may

light up or switch between orange and green after the system LED

turns on. The system then runs the power-on tests. While the tests are

running, the BIOS beeps or additional messages appear on the

screen. If you do not see anything within 30 seconds from the time you

turned on the power, the system may have failed a power-on test.

Check the jumper settings and connections or call your retailer for

assistance.

3.2 Powering off the computer

You must first exit the operating system and shut down the system before

switching off the power. For ATX power supplies, you can press the ATX

power switch after exiting or shutting down the operating system. If you

use Windows 95/98/2000/XP, click the Start button, click Shut Down, then

click the OK button to shut down the computer. The power supply should

turn off after Windows shuts down.

The message “You can now safely turn off your computer” does not

appear when shutting down with ATX power supplies.
