6 Turning On the Power
Cautions
• 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 off the PC immediately after you turn it on, wait for the OS to startup and turn off the
power according to “Turning Off the Power”.
• 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 POST detects an error, an error message is displayed.
• During system startup (including contract on unpacking) or system shutdown, or when the Virus
Scan window appears, the band-like noise may appear for a second. This does not indicate a fault.
• When the upper cover has been removed for installing a peripheral device, make sure that the cover
is installed before turning on the power.
• When turning on the power after turning it off, wait at least 10 seconds.
