Hardware Power Switch

tactile pushbutton switch. This switch controls the power on/off of the system.
This switch turns the system on when pushed only when external power is
present. This switch turns the system off when pushed again during power on
status. However, if the system hangs due to any reason such as software
resource conflict a simple push on the switch may fail to turn off the power. In
this case, please utilize the forced power off feature by pressing the switch
and holding for within 10 seconds. In case the turmoil is so vigorous that some
hardware registers may be confused causing trouble for system restart or even
