In my experience with other computers, NVRAM goes flat faster when
the machines have no power. Desktops don't run on battery, so for
them that means when they are turned off. It seems to make sense, as
that is when they would be drawing power.
My main battery went flat about a year ago, and as I very rarely use
the Libretto on battery, I have not replaced it. (I have a new
battery, but I don't put it in the machine, because I don't want
another battery to exhaust its recharge cycle limit before I
get to use it...). So far, I have never had a problem with
my CMOS battery.
Of course I never bother disconnecting it from the mains, even when turned
off, except when moving the machine, so I suspect that is as good as having
a battery in place.
