I have a windows 8.1 samsung ativ book 4 laptop.
It's an Intel i5-3230M @ 2.60 GHz with 6 GB ram, 64 bit. Generic Intel 4000 graphics card. Standard stuff.
This issue is quite odd and I have never run into it before. When I change power plans, it should be either accelerating or decelerating my processor speed, but it doesn't. It is remaining consistently at 1.17 GHz and CPU usage is generally staying under 25%.
I do recall that while playing SC2, it began heavily lagging and dropped frames to 1-2 fps and I had to alt f4. I am wondering if either a) my laptop is stuck on power saving mode (for some reason?) or b) if there exists some background program that runs when laptop overheats/overextends its capabilities and somehow put itself on some sort of lockdown. I don't know the possibilities, I am no expert in this field.
According to SpeedFan, my CPU temp is ~60 C, pretty standard.
I checked BIOS; nothing stood out.
The only thing I changed today was downloading the Logitech Gaming Software, as I just received a new Logitech G100s.
Any help or suggestions is appreciated. Thank you.

Do you possibly have quiet mode on? I also have a Samsung notebook (although a different model) and that behavior sounds suspiciously like quiet mode. On my keyboard, the hotkey to turn it off is Fn + F11, and the F11 key has a fan symbol on it. You can also open the Samsung settings program (Fn + F1 or just find it in the program list) and turn quiet mode off that way.

It's quite possible that it's overheating since that can be a sign. Does it feel hot when you're playing? I know from my experience that when I used to play SCII on my laptop (some similar specs), my temps were getting up to the 90s which is a bad idea lol and it would feel hot. You said temp is 60C, did you have speedfan on during the game as well? 60C at rest sounds ok to me and I'm guessing that's during rest otherwise that's one hell of a temp to have during load XD
If not, I would look into what city42 said. It's quite possible that you have a setting that allows you to manually change your cpu speed and you've turned it on by accident. Other than that, shutting down and letting it rest a bit before starting is a good idea (same with cleaning if you've had it for a while now).
Finally, I recommend this for monitoring: http://www.cpuid.com/softwares/hwmonitor.html
Turn it on, play a game then check what the max after you finish or alt-tab out during the game if you are getting 1-2 fps etc... to check. Best of luck and keep us informed!

Laptop case temperature is not really closely linked to CPU temperature, because heat and temperature are quite different and CPU itself can be very hot while not outputting much heat (confusing at first, i know)
idle readings for clock speeds and temperatures are not worth much, you need readings at load

I'm also having some issues with my laptop's cpu frequency. Mine is the opposite of yours, my cpu always seems to be running at max frequency + turbo boost even when idle (3.3ghz) unless I used the "power saver" plan, in which case it's capped at 700mhz which is way too low even for web browsing.
What's annoying is that manufacturers have replaced good old BIOS by this UEFI crap that does not provide any information about EIST/speedstep.
Basically, out-of-the-box, the powerplans are completely broken.

Great job, it was this. Truly amazing how you knew! Someone actually told me about this on reddit tech support a few hours ago. But I still don't understand, if you don't mind explaining: my Silent Mode was on Auto the entire time for the past 7 months. Why now did it become an issue? The guy said it took him months to figure out, and I believe him because these two things seem unrelated... Why does the fan have to do with CPU usage?
I also have that fan hotkey on f11 haha. Now I know what it's for.

I know right? People recommended I look at speedstep-- welp there is no speedstep! And it is unbelievably ridiculous how hidden it is to reach the BIOS with windows 8.1. Had to youtube that shit-- click like 10 different settings then finally reboot comp.

Ha, it's your lucky day. I clicked on the tech support forum by accident and the title of this thread caught my eye.
No idea why Auto mode suddenly became an issue, but you can just toggle between on and off with the hotkey when you want to use it. As for the second question: quiet mode works by slowing the CPU fans so that they are practically inaudible. If the CPUs were allowed to go full throttle with such little airflow, overheating would become a problem. To prevent this, they give the CPUs a ceiling of ~1.2 GHz to keep the temperatures reasonable. Even with this slowdown the temps go up a little bit, which explains your slightly high reading of 60 C (assuming that's at idle).

Perfect explanation, thanks! Now to figure out why it became an issue in the first place....
