apparently utter and total noob here understanding or making use of
power saving methods on laptop on current leap here.
major brand rather current generation laptop hardware here. default
leap with kde install.
when i sleep (technical name: suspend?) the laptop from via kde menu
or close the lid, it still eats away huge amounts of the battery of
this laptop. also it plays sounds and clickery effects from the
speaker when for example i turn off my power outlet (switch off power)
for example. the laptop apparently doesnt sleep at all or i have very
different understanding and reasoning what sleep would mean.
coming from a windows world, my (older) laptops back ages ago really
went still, powered down the cpu and memory and disks, would not cause
heat at all, or barely eat away the battery at all.
i am not talking memory-saving-to-disk here at all (technical term:
hibernation) thats what I am trying to avoid, as it really writes away
so much amount of ram completely to SSD these days, and still takes
like a lot of time.
i am first trying to make use of normal sleep (suspend). i wonder if
linux is so incapable of saving power to begin with, or if this is a
configuration issue, or an opensuse leap issue or kernel issue or
for example: when i put the system to sleep via kde menu, the close
the lid only after that, i have the feeling that the system still
reacts to the lid even as if it would unsleep the machine again, like
a switch button, sleep from kde menu = suspend swith pressed. lid
closing = suspend switch button pressed once again thus un-suspend
waking it again.
when having the lid closed and i turn off the laptops power then
(unplug it from ac socket etc.) then the laptops creates sound in
reaction to that, showin the user (me) that some power event happened
or once again suspend switch pressed once more figuratively.
this all dont make sense to me, how can an already sleeping laptop in
the fist place react to closing the lid. in my universe that would
only acknowledge the wanted sleeping suspend state by the user, but
apparently it is not. then pulling the ac power after that even
creates for another contradicting event on addition on top of that.
i am really confused. my windows machine once put to sleep, does not
generate sounds, and does not re-ware up or change its state when i
pull the plug, or reconnect the ac plug and more.
i am seriously missing the KDE configuration gui what happens when i
close the lid and when i pull the power etc apparently there is only
three major categories as a state of things, running on ac, running on
battery and running on low battery. but this does not reflect my true
reality of things.
what am I getting wrong here?
