    I had same problem CPU running at about 25% of full seed frequency.
    Tried setting power options as described without success.

    This hapernde to me when I disconnected / connected my notebook to a docking station.

    Solution for me
    – in parallel to the docking station, plugin power supply directly to the notebook.
    – CUP speed increased directly to max frequency.
    – When I disconnected power supply from notebook, the, for a short time CPU frequency decreased again to about 25% but a tick after raised again to full speed.

    In the bios settings I disabled intel speed stepping and that fixed the problem for me

    Method 4. Disable the 'intelppm" service from Registry.
    Worked for me.
    Thanks TEAM

    It seems like everyone got a solution at no. 4. But ai tried the same thing, it didn't work…. my laptop works fine for a minute or so, then, th cpu clock, gpu clock and ram clock everything gets down to 1600, 400, 200 MHz. It happens when I play games. Ryzen 7 2700U Apu

      Re-check the article. I updated it with one more method to fix the issue.

    My 2.80 GHz CPU was running at just 0.35 GHz… I tried Methods 1 & 2 without success, then I read the comments and noted a number of people reported that Method #4 worked.

    I tried #4, but it didn't help, either, so I searched some more, and found a forum that stated an under-charged battery could cause this. I shut down the PC, removed the battery and powered it with only the A/C power cord. I restarted the PC, and VOILA! It is now running at 3.0 GHz or higher…

    The battery was fully charged, BTW, so now I need to figure out why it had this effect.

      I had a similar problem. My laptop battery had passed it's service life and was no longer holding much charge. After Windows 10 1903 update I faced many performance issues and noticed the cpu speed was forcibly slower. I eventually mangaged to bypass this by setting the Start value in the registey to 4 (disable power management) which cpu then ran at max speed. I have since replaced the battery, resetting the Start value to 1 and all is back to normal. I suspect that the old battery's electronics could no longer operate correctly with windows and the power management dropped the performance, possibly to protect the laptop, my guess. All's well with new battery.

    Thanks ,I used m4 , I have i7 7500 and now it's running @2.9Ghz . but the problem its not using turbo boost ( i guess that's what they call it) since it's capable of reaching 3,5Ghz any idea how to unlock full potential??

      @Jawhar: 1. If you own a DELL laptop make sure that you're using an original DELL AC adapter. 2. Enable the 'Intel Turbo Boost Technology' in BIOS settings.

    All methods tried, but only Method 4 made a difference. A variation worth trying is as follows. Setting the Start value of intelppm to 4, as in the instructions, caused my cpu to run at full speed (2.3GHz) at all times. I tried other Start values, the best being a value of 1. Now my cpu runs at 2.3GHz when needed, and drops down to lower speeds when it can. This probably allows cooler running of the machine, less fan noise, etc, so that's how I will leave it.

      i had the same experience. Setting Value to 1 is i believe the best solution

    Method 4, Perfect thanks and no it doesn't run constantly at full load, if it does you have additional problems. If you also used method 2 don't forget to re-enable normal startup afterwards …. A tip for slow laptop users – Cortana is a cpu hog, if you don't use it then disable it in the registry (google it).

    Not really a solution. It did fix the CPU clock in Task manager->Performance->CPU but it did not actually solve my issue. I used CPUID HWMonitor and it still shows my CPU clock rate at 800 MHz.

    My 2.8 GHz computer was running at 0.39 GHz, about 14% of it's capacity. After disabling the intelppm service via the registry, my CPU is now running at 2.8 GHz again.

    Thanks!

    Changing the registry setting to 4, worked like a charm. Using a Lenovo ThinkPad T430 Intel i5 3320m. Processor used to be at 46% of its capacity, now it reaches 100% when necessary. Thank you.

    It happens sometime after a Windows Update. Just update driver for each processor from Device Manager\processor.

    Method 4 locks CPU in constant 100%. Not really a solution unless you don't love your pc.
