CPU usage always below 40%

[Anshul Gumber]

Hi i am usinge i3 laptop and facing issue Cpu always use below 40% of its total power even while rendering and benchmarking please help me how to sort out this issue using

windows 8.1 64 bit currently same issue was on windows 10 . It effects my laptops performance and alot more because its i3 2nd gen processor

Power saver mode enabled? try setting to recommended?

Tried that stetting already . Even tried setting everything at max

Does it go to 100 when you plug it in?

[Some random guy 23424234]

tried to find driver of intel thermal dynamic management, or something like that. Check on your device support page first.

I had the same problem with my laptop

Okay, how are thermals? Any chance it's thermal throttling and down clocking itself?

Can't say but tested when its completely cooled and is shut down for hours boot it up and put it to benchmark same at 40 %

CPUs can heat up very fast. Is it a constant 40% or does it fluctuate? A constant 40 sounds strange

Nope means below 40 even when rendering videos and benchmarking it goes below 10% on normal browsing stuff

Okay, if you could find out your cpu thermals for me that would be great. 

Since it's an old laptop (I assume) I feel like it's a problem with old thermal paste or it's dusty and it needs a cleaning. (assuming thermals is an issue aswell)

Normal browsing stuff sounds fine at 10% since that doesn't use very much cpu load.

I gather you have checked your advanced power management settings?

 

When I re-installed windows a few weeks ago on my server, I discovered it had been set to 70% max even on performance mode... didn't find that out 'til I was benchmarking it one day and wondered at the low score. Must be a bug in windows power management maybe as I've never experienced it with any other windows install or rig.

So should i try windows 7 for my laptop because 2 years back it was on windows 7 and was working fine

go on panel control, energy saving, change combination option, change advanced energy saving option, cpu energy saving option, max cpu performance ( i'm not from usa/england, so i don't think it's perfect what i wrote, but it's a traslate from my language.) and see if the % is 100 , because even 99% will make the cpu stay on very low clock, those old cpu have few steps, for example, my i5 2540m , at 99% max performance stay at 998mhz over the 3.3 ghz, i use this for battery saving, because it will save you battery HUGE, even if you do very low cpu things, because it will not continuily go up to max speed for like 0.001sec and that use a lot of energy, and will not make the fan start.

 

for windows 7 thing, maybe you had the same problem on windows 7, because task manager on windows 7 says to you are using 100% even if you are on low clocks, win 10's task is more accurate, use hwmonitor as other people wrote, to see the real clocks of your cpu.

No, just go into power management and check the advanced settings, especially where it concerns CPU usage... with it being a laptop, you should also check the advanced settings for when laptop is plugged in/not plugged.

Did you try to plug in the AC power cord ?

Some laptops have huge power saving modes when on battery.
