When your system is not operating correctly
Turn off the power, and then press and hold the (Power)
button on the system for at least 7 seconds to turn on the
power again. Then connect a controller with a USB cable, and
press the (PS) button on the controller. The safe mode
screen is displayed. Safe mode is a start-up mode for your
system, in which only a few system functions are available for
solving problems. If the power will not turn off normally, press
and hold the (Power) button on the system for at least
15 seconds. The system restarts, and the safe mode screen is
displayed. Once the system has entered safe mode, select the
necessary items, and follow the on-screen instructions to
perform operations.
