I have heard that there is some resistor near the CPU. If this resisitor is desoldered the problem with the BATT is solved...
Is anybody knows which resisitor is this?

@CellM@n
What do you mean with "change resistor"?. Just remove it?. If it is really a change then, what's the new resistor value to solder?
