I've tried this already since the current voltage has fallen below the booting threshold, by supplying extra current from a separate supplier directly to the battery receptors. Yet i think Michael, that we are not dealing with a dead battery that needs reviving, but with a broken protection circuit that does not accept the charging current. If i could suggest a solution that would be first to deeply-discharge the battery in order to reset the protection-cpu, and then start charging it. Is this a viable solution?
