as i was typing the previous message replying you, i don’t know what did i accidentally pressed… after the msg posted, i just realized my laptop screen is totally blanked… on the 2nd monitor is on… .what turned off my laptop screen ? 
Since I only got one monitor I haven’y got an inkling on what to do. Hopefully some true KDE wizard will read this. 
When it comes to sleep/hibernation, I assume that you got a sufficient Swap file set up?
On a related note: Swap or not?
I’m not following a whole lot of this to be honest. What do you mean by “Suspend” That’s not an option in energy saving in KDE.
It sounds like what you think sleep means is to hibernate, and “suspend” is actually sleep.
Sleep means your screen goes blank and your computer is basically ready to roll when the screen is opened.
Hibernate means your computer saves all of your RAM to swap and shuts down. When you open up again, you power up and resume from where you were.
Suspend means. . . . well, I don’t know.
If you want it to hibernate, and since you’re not seeing hibernate as an option in energy savings - two things are true. You didn’t setup a swap partition on installation, and you either didn’t setup a swap file OR you did so incorrectly. If you set it up correctly, KDE knows and will immediately show up as an option in energy savings.
What are you actually trying to accomplish?
Suspending will not power off the RAM , so when you opens the lid it starts much quicker .
Also in Plasma sleep means Suspend and not turn off screen
So, technically everything is some sort of suspend. So yes, sleep in kde would be suspend to RAM. Not turning the computer off. Computer will be ready to roll when the lid opens. Suspend to HDD/SSD would be hibernate where it gets written to swap and the computer would turn off.

You probably hit the display switcher and selected output only.
no, i have not personally setup any swap. however it can suspend… did suspension many time without a problem.
i will post on a new thread regardin suspend issues. less confusing this way.

actually i am kind of giddy with all these terms…
but i do know suspend is with power consumed on some memory chips only. hdd is stopped. so i can move my laptop here and there without causing hdd damage.
as for hibernation, it is totally make a swap of all those in ram… so that i can totally power of pc…
as for sleep… i have no idea what that is.
lol…
u and i got different opinion on sleep and suspend. lol
i say suspend is pc ready to rock and roll as soon as out of suspend…
it is ok, this way solved.
it was that i can’t put laptop to sleep / or suspend when i close the lid… and i can’t find the place to enable lid close = sleep/ suspend.
but i have since found it and it works.
i can accept “sleep=suspend” , but what do you meant by Not “turn off screen” ? when my pc suspend, it always turn off screen… it is blank…
oh… on wiki said there are 3 types of suspend… ram suspend, hdd suspend and hybrid of both.
is there way to know what being suspended when i close my laptop lid ?
i wonder which suspend i have got… i think hybrid… becaus hdd seems to be not moving… i need both to suspend, ram and hdd… so that i can move my laptop vigoruosly… for example, i often suspend or sleep my laptop and bring it in my backpack for a 20 mins journey. i don’t need hibernation for that short duration. as supend draw little power.
i was thinking the same, but i don’t know what button to press to recover my laptop screen. it is still blank…
any idea which button combination ?
I don’t think I could be more confused as to whatever it is you’re trying to say here.
You can have whatever opinion you want. In KDE, suspend (at least on my computer) is not an option. I cannot help you suspend your computer in any fashion without specifically figuring out whatever you’re actually trying to accomplish. I’m not after an opinion, these are the possible choices I can help you figure out on your computer.
These options can all be found under Energy Saving
Yes. Suspend to RAM is sleep. Suspend to HDD is hibernate. The rest can be found in Energy Saving

all i want to say is, i want my laptop to suspend / sleep with suspend hdd and everything apart from rams…
ic. suspend to hdd is hibernate. ok now i understood.
thx.
You will need to setup a swap partition with installation which will automatically make hibernate available in Plasma. Or if you don’t want to repartition/reinstall, you can setup a swap file to enable hibernate. It’s been covered here before, or you can find out more here: https://wiki.archlinux.org/index.php/Swap
I’ve been using this guide for a while now, and it still works perfect if you’re using the LTS kernel. Fallocate has been deprecated in the newer kernels now though. You must dd the swapfile now, but everything else is still relevant.
Also, maybe I’m just being petty. But, this isn’t a txt to someone. ic, u, thx. Capitalize. Punctuation. ic is “I see.” If you can’t take the time to type out coherent complete words, especially in a distro where even capitalization in terminal matters, it makes (me) feel like you’re lazy and don’t actually care. And makes me severely not want to even help. I honestly wouldn’t have if @Mr_Ecks hadn’t tagged, or accidentally tagged me in here.

i will try that later. but can you help me with my mousepad and mouse scroll pls. i got a post on that. randomly things happened. i didn’t do anything… it just happened. 1st, my mousepad not working right, (it auto solved). then i realized usb mouse scroll button not longer scrolling. then i found out my touch pad “tapping” not working, i have to rely on left click button on mouse pad… “tapping not working”. also realized double clicking on application window title bar does not “max screen” the app.
Ok. I respect your view. I will type better next time. Thanks. You are just like my older brother who also demand me to type properly… lol
Your mouse settings are under input devices. Please go thru the entirety of your settings, one by one, top to bottom. Many of your issues can be solved within your settings. Part of the fun of KDE is that everything can be changed. If you want something that just works a little easier, with less customization and similar beauty, please check out the Cinnamon desktop environment.
