Powering On your System
Caution: Never turn off the system before the characters following the Boot-
BIOS logo are displayed on the screen.
Power on your system as follows.
1. Connect the power cord of your system. You may need to wait 30 seconds
before pressing the power button as mentionned in step 5.
2. Make sure all external devices, such as a video display, keyboard, and mouse
(optional) have been connected, and that their power cords are connected.
3. Power on the video display and any other external devices.
Note: If the system power cord(s) is connected to a power control unit such as
a UPS (Uninterruptible Power Supply) make sure that the power control unit
is powered on.
4. If applicable, open the door behind which the power button is located.
5. Press the POWER button to power on the system. The POWER lamp lights
green. If it is does not light, make sure that the ac power cord is connected to a
functional ac power source.
After a few seconds your system begins the internal Power-On Self Tests (POST). The
POST automatically checks the system board, CPU(s), memory, keyboard, mouse, and
most installed peripheral devices. It also displays the start message of the BIOS setup
utility.
The POST check results should be especially monitored in the following cases:
■ When the system is being used for the first time.
■ When the system appears to fail.
■ When the system beeps many times between power-on and the OS start-up.
■ When an error message appears on the screen.
Note: For error messages that appear on the display unit, refer to “Error
Messages” on page 163.
Always allow the POST to complete before powering down your system.
If you have problems powering on your system, refer to “Solving Problems” on
page 148.
If an operating system was factory-installed on your system, you can start using it.
If not, insert the ExpressBuilder disc into the optical disc drive, reboot the system and
follow the screen prompts to run ExpressBuilder.
