Arduino PRO Mini - The pads [was "jumpers"] on the back and Low Power Consumption I've noticed that on the back of an Arduino PRO mini are two Jumpers next to the A4 and A5 pins, marked with red in the following :



Looking at the leads one seems to be a bypass for the POWER Led and the other a bypass for the regulator, but not sure. 

Further, the schematic reveals just one Jumper SJ1 :

So, my questions are :


Why are there two physical Jumpers on the board ? 
Are these two jumpers actually just one : SJ1 ?
And if so how to connect them in order to enable Power isolation ?
Both responses are correct but be mindful that this is a SparkFun feature.  An Arduino Pro Mini from China won't necessarily have the SJ1 pad.

1) Like Gerben said, the pads on the underside of the board are for I2C pull-up resistors.

2) Like David said, SJ1 is on the top of the board next to the GND and RST pins.  (It looks like a small solder blob.)

3) To isolate the regulator from VCC, remove the solder blob on the top of the board with a sucker or solder wick.

The Sparkfun schematic shows all of these elements:
