    Slow and Sluggins when power is below 50% even when plugged in

    Hello ladies and gentlemen, I’m in need of some advice. I’ve be having some issues with my machine. Please forgive me if this has been discussed already. I have searched and found a similar issue but not quite with all the details, so here goes.

    I’ve done a clean install from windows 8.1 to 10 home. Since then I’ve been experiencing slowness and lagging when my power level is below 50%. Weather it’s plugged in or not, the machine just lags. Once the power is above 50%, everything runs normally.

    I did download and install Group Policy Editor to see if there were additional power management settings I could tinker with. However after doing the Global Policy install, a component in the advanced power options became available that seems like it could potentially solve this issue.

    I can now modify the Dynamic Platform and Thermal Framework settings, these options seems like they could help with the slowness but I don’t know too much of it besides what I’ve read. I have some knowledge of the “Power Limit” and “Acoustic Limit” settings, however, I don’t know what the “Low Power Settings” do. For that matter, do you think this is a potential fix? How should I set these?

    Any help would be greatly appreciated. Pic 1.pngPic 2.png

    Help!!!! CPU operating at only 0.51 GHz

    Can someone please help? Experiencing sluggish performance and could barely browse the web.

    The CPU is operating between only 0.51 and 0.53 GHz. Normal operation for me is usually 1.17GHz - 1.30 GHz. This behavior is happening with or without the machine plugged in.

    The machine is currently plugged in and battery is at 78%.

    Please help, any advice would be appreciated.

    It's normal. CPU throttles back to save power. Watch it when you're actually doing something intensive.

    Thanks for your reply!

    I understand how the CPU throttling works to some extent and this behavior would be expected during a time when the battery is low and trying to conserve power, or even when the battery is charged fully but the load of work in very light.

    In the past, during normal operation where I would have three web browsers open at once, everything would be quick and zippy, the processor would be at around 1.17GHz.

    But now it doesn’t seem to be able to operate at anything higher that 0.53GHz. Not even when I intentionally take the work load couple notches up.

    Ok, I’ve made some progress. I installed “Processor Power management” which is usually found in power options. Now I’m able to adjust the Minimum and Maximum power state. I adjusted it accordingly and the processor seems to be operating the way it should. It actually operates just as you describe earlier, it’s basically fast with heavy loads but slows down when the load is very light.
    It’s currently on battery power at 80%. Can I expect this behavior to be consistent even when the battery is around, say 30%? Because even at 30% in a situation where I can’t charge, I still need it to function without lag under heavy load.

    So I’m still having this issue. After installing “processor power management”, things were looking good. The throttling seemed to work exactly as it should. Computing speed would increase over heaver load, and when it was not as active, computing speed would decrease.

    Well I let the machine sleep for about an hour during my lunch period. I came back from lunch, tried opening web browsers and some other apps, it just lagged and took a long time to do anything.

    I looked at the processor in task manager and it’s just ranging between 0.51 and 0.56GHz. The speed just won’t increase.

    maybe your processor is bad or thermo regulation is not working right. mine died last month and had similar symptoms. check event viewer for any errors or warnings that mention processor. do you have any error screeens?

    “Processor Power management” was not shown in my options & it was running 100% all the time. Maybe why the battery was running down when asleep?
    You can watch all 4 cores with HWInfo32.

    Checked in Event viewer, this is what I’m seeing. This message seems to be generated to all four cores of the processor. Keep in mind that this wasn’t an issue at all when I was running 8.1. Once I installed 10, along with a BIOS upgrade, I noticed the lagging. When the machine is around 80% and plugged in its fine. Today, my wife watched some online shows and drained the battery to about 10%. Once I got it back, I plugged it in, it’s currently at 55% but still lagging.

    “Kernel-Processor-Power (Microsoft-Windows-Kernel-Processor-Power) Event ID 37”
    “The speed of processor 2 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report.”
