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.
Make sure all external devices, such as a video display, keyboard, and mouse
(optional) have been connected, and the power cords are connected.
2.
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 an UPS (Uninterruptible Power Supply)
make sure that the power control unit is powered on.
3.
If applicable, open the door behind which the power button is located.
4.
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 messages of the BIOS setup
utility during execution.
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,
see “Error Messages” on page 253
