6 Turning On the Power
This section explains how to turn on the power.
■ Notes on power-on
● The power lamp lights up in orange in the standby mode.
● Before turning on the PC power, confirm that the display is connected to the PC unit. If the PC
power is turned on with the display disconnected, the system fails to recognize the display
adapter and the screen may not be displayed normally. In this case, analog display users
should connect the display, terminate the OS, turn off the PC and turn on the PC again.
● When you use a digital display that takes power directly from a wall outlet, make sure that it
is turned on before turning on the PC. The digital display does not work if it is turned on after
the PC unit. Turn off the PC unit once and turn on the display and turn on the PC unit.
● When the power cable of the display is connected to the PC, the display power is turned on or
off automatically when the PC power is turned on or off. Therefore, once the power switch on
the display is pressed, subsequent operation is not necessary.
Therefore, the display power is automatically turned on each time the power switch on the
PC is pressed as in Step 2 below.
● If the screen display is not centered, check if the screen refresh rate is set in accordance with
the display. If the problem persists, adjust the display.
● When turning on the power after turning it off, or turning off the power after turning it on, wait
at least 10 seconds.
● At the beginning of a screen display (such as the Windows startup and shutdown screen) or
when the display mode is changed (for example, from the power-saving mode to the normal
mode), the screen may be distorted temporarily or display horizontal lines. This does not
indicate a fault.
● When the PC is turned on, the system performs POST (Power-On Self-Test) to check the
internal hardware components. Meanwhile, the Fujitsu logo appears on the screen. Do not
turn off the system during POST.
● When the upper cover has been removed for installing a built-in option, make sure that the
cover is installed before turning on the power.
