• Automatic restart deals with cases when you accidentally unplugged the AC power cord or
unexpected power outages. By keeping the power flag ON, after the resumption of power,
the machine will start up automatically.
In rare cases, when you reconnect the AC power cord to a power outlet, the machine does not
start automatically. In this case, the machine has not failed. The cause is due to the timing of
releasing the residual charge. If you press the main power switch while the residual charge was
already released, the power ON flag will not be set. At this time, start the machine manually by
pressing the main power switch.
Shutdown Method
1. Press the main power switch on the left side of the machine.
2. Take out the power cord
3. Wait 3 minutes (this is the time required if you will remove the rear cover and access the interior of
the machine, to take out the controller board for example).
• If some LEDs on any of the boards are blinking or lit, current is still flowing. After the shutdown
process, the main power is turned off automatically.
When the shutdown is complete
Main power LED: Off
Operation panel LED: Off
• How to start from shutdown
• To start the machine, press the main power switch. However, if you press the main power switch
between the beginning and the end of a shutdown, the machine will not start.
Forced Shutdown
In case normal shutdown does not complete for some reason, the machine has a forced shutdown
function.
To make a forced shutdown, press and hold the main power switch for 6 seconds.
In general, do not use the forced shutdown.
• Forced shutdown may damage the hard disk and memory, and can cause damage to the machine.
Use a forced shutdown only if it is unavoidable.
