JP19 is used to select the method of powering on the system. If you want the system to
power-on whenever AC power comes in, set JP19 pins 2 and 3 to On. If you want to use the
power button, set pins 1 and 2 to On.
When using JP19 “Power On” feature to power the system back on after a power failure
occurs, the system may not power on if the power lost is resumed within 5 seconds (power
flicker).
Note:
In order to ensure that power is resumed after a power failure that re covers within
a 5 second period, JP19 must be set to pins 2-3 and the “Power Failure Control” in
CMOS is set to “Always On”.
JP5, JP14 and JP21 are used to select the power of the USB ports. Selecting +5V_standby will
allow you to use a USB device to wake up the system.
