RE: A86: Re: power down




Okay, because I remember one time I had some kind of assembly program
installed (it might have been an Alpha-lock one press type deal) and I
turned off the calculator with pretty new batteries installed then the next
morning it was dead.  Since then I have been hesitant to leave anything in
low power mode (shells, etc.).

By the way, what kind of code is used to find remaining battery life?  I
assume there must be something since the calculator can tell when its
batteries are low.  How does it tell that?

Much, much less.  The screen is turned off by the <out (3), a>, so
there's a major power usage drop.  The halt effectively shuts down the
processor and leaves it waiting for you to wake it up;  in low power
mode it should use amounts of power that would only be noticeable over
long time periods, like, say, years...
