The S6LX16 Rev B board has an issue if you try to power up the board using the optional 12V supply without the battery or USB cable plugged in. A work-around has been designed for this problem.
Work-around: Remove component U15
By removing U15, regulator VS6 will always be enabled as it has an internal pull-up on this signal. This allows the rest of the circuitry to turn on as expected. The side affect of this work-around is that it is possible that MXP or PMOD expansion boards will remain powered even when the switch is in the CHRG position.

I just want to mention that you can achieve the same thing by lifting the pin4 of the U15 rather than yanking out the device.
