Why if you are on AC power does it matter, if the user chooses to not

once switching to battery? I do not think I get what you are trying to
tell me. I do not use pm-powersave or anything like that I just use a
simple handler.sh with acpi. Doing it the way I said and only caring
about power on battery since that is when I need it to last, I have gone
from a simple 1.5hrs to well over 3.5 hrs on battery. Again why does
what the wattage on AC really matter.
first of all, if you're acting as a server in a datacenter it really
matters.
second... burning power in once place will reduce performance in other
places; more and more things in systems are now thermally limited; for
example, the CPU turbo mode is limited if the system gets warmer.
likewise, things like that are current supply limited. Also, your
battery will charge slower if system power consumption is higher...
and.. if you burn a few more watts, that's CO2 you're generating for no
good reason.
anything that you tune either should be always tuned (e.g. free)
or involves a tradeoff, for which the question pretty much never is "am
I on AC", but "can the user tolerate X right now". Once you ask that
right question, and solve that, then "on AC" will turn out never be in
that picture.
And me being the user choosing to do it the way I have stated on a
laptop is incorrect then you're saying? I am not one to be concerned
with CO2 or any of the crap. I am not an eco conscious person nor do I
care to take the time/effort/knowledge to do it properly. I have
everything set to default program values or OS default values on AC and
then on battery go into a more strict policy and go about it in the
manner you state. Again I see no way I am really "wasting" power or
"adding to CO2". Plus how do you know me as the user does not live
rurally and relies on solar power only? (which I actually do)
Also why have I not seen an increase in charge time for my battery if
this is the case as well? My charge time has not increased any, and I
feel its VERY reasonable in the charge time for the battery capacity.
You state that performance will drop if I am wasting power on AC, well
where is this said performance loss? In relation to? I have never
noticed a performance loss on AC power by leaving default values, also
when on AC power most would tend to do a more intense use of the
computer as they do not have to worry about power usage then. Also I
think adding in many "power" related run time programs defeats the
purpose of trying to save power hence me only using a handler.sh with
acpi and nothing else.
It is my electricity so I feel its my choice in how I use it and still
do not see how any of this stuff relates to me offering info about the
CODEC that the OP is talking about. If I am OK with the amount of time
it takes to charge then there is no effect to me as the user, which of
course in the Linux way, may not be compatible for you or to your
liking. I am just concerned with lower wattage usage on my battery and
that CODEC is running in the manner the OP stated and how I stated.
Would be nice to get info pertaining to that.
