when the computer is connected to an ac power source but is not turned on, the operating system does not run, and all core logic is shut down; however, the computer can respond to remote requests to turn on the computer. the power-on

    led flashes to indicate that the computer is connected to an ac power source but is not turned on (standby mode).

    1. turn on all external devices, such as the monitor, before turning on the computer.

    2. the power-on led on the front of the computer is lit when the computer is on and while it is powering-up.

    3. you can install a circular disk over the power-control button to prevent accidental manual power-off. this disk, known as the power-control button shield, comes with your computer.

    approximately 20 seconds after the computer is connected to ac power, the power-control button becomes active, and you can turn on the computer and start the operating system by pressing the power-control button. the computer can also be turned on in any of the following ways:

    1 if a power failure occurs while the computer is turned on, the computer will restart automatically when power is restored.

    2 when you plug in your computer for the first time, wake on lan can turn on the computer.

    3 if your computer was previously turned on, it must be properly turned off for the wake on lan feature to turn on the computer.

    what you see and hear when you start your computer depends on the features that are installed and the settings in the configuration/setup utility program.

    if power-on self-test (post) detects a problem, there might be a series of beeps or no beep, and a numeric error message might appear on the screen. write down any beep series and error code numbers with descriptions, and then see

    “troubleshooting charts” on page 78 for the explanation of error codes.

    during startup, the following messages might be displayed briefly:

    1 to start the product recovery program, press f11

    2 press f1 for configuration/setup

    3 [[[ press [ctrl][c] to start lsi logic configuration utility ]]]

    to use any of these features, press the appropriate function key or keys quickly.

    the messages appear for only a few seconds. for more information about the programs listed in these messages, see “using the configuration/setup utility program” on page 21, “using the lsi logic configuration utility program” on page 24, and “recovering your operating system and preinstalled software” on page 86.

    during startup, you might not see press f1 for configuration/setup. if you want to see the prompt, see instructions for displaying the prompt in “using the configuration/setup utility program” on page 21.

    use the configuration/setup utility program to configure your computer with passwords, pci adapter configuration, and other options. the configuration/setup utility menu is displayed at the top of the screen. to navigate the menu and screen items, follow the instructions on the right of the screen.

    the operating system and application programs start from the hard disk. if your computer is attached to a network, the computer will begin attaching to any lans and remote applications to which you have access. a network administrator can also “wake up” your computer (start it remotely) to download programs or gather information about computer performance. for more information, see “wake on lan” on page 18.
