This sounds a rather odd problem, why should the RTC only stop counting when
it is being powered from the battery rather than the mains? Obviously, there
is still battery power to the RTC, otherwise it would lose the time
completely (possibly be reset to Jan 1st 1990). Sounds to me like it is
something that has been purposely built in to the RTC chip for some reason,
and that there must be some way (using IIC_Control) of restoring normal
operation, possibly to keep a record of the total length of time a machine
has been in use? Obviously this 'function' is not intended to be used on the
Arc.

But why should the effect be 'more severe' on an A3010? (I assume the same
RTC hardware is used)
