Automatic Power ON

From NAS-2000.org

This circuit automatically switches on the NAS if there is power.

The functionality of the ON/OFF button is not affected.

Three connections to the board are required. Two at the connector CN4 or the cable of the ON/OFF button and the third (+5V) can be soldered at Capacitor TC5 +pin (bottom of pcb) or on the voltage regulator Q2 I-pin (top side).

The voltage rating of the capacitirs must be 6,3V minimum. The transistors may be any type you have available.

Note: be careful when touching electronics. Electrostatic discharge will destroy your hardware!
