    Prevent Cpu throttle on Battery


    Hello,

    I recently upgraded my Laptop by adding an SSD with windows 10 pro.

    Now I noticed the computer throttles the cpu frequency whenever I'm on battery even on high performance profile.
    (In task manager I can see cpu frequency instantly dropping from 2.3-2.5 to 1.2 GHz as soone as I unplug the AC adapter).

    The issue is not bios related and It does not happen on Ubuntu nor window 7( I mesured and the cpu frequency does not change when I unplug).

    I tried the following:
    - High performance profile.
    - increased "minimum processor state" in power plan settings to 60% (https://i2.wp.com/www.techconsumergu...ng?w=452&ssl=1)
    - Computer Configuration > Administrative Templates > System > Power Throttling Settings and I Enabled the "turn off power throttling"


    Still windows 10 throttles whenever I'm on battery.

    Can someone suggest a solution for this?

    Thanks in advance

    The only solution is setting minimum processor to 100%

    Hey, Thanks for your answers, while I don't see why my 60% won't work and 100% would work, I still tried your suggestion and it didn't work. Also on AC minimum is set to 5% and it still works...

    My current settings:



    I already had the minimum and max. options appearing in my menu, so I guess I don't to do the commands in the tutorial, right?

    Correct. No need to add the options if already there.

    Next, check the min and max processor frequency to make sure they are set to 0 for unlimited.

    Change Maximum Processor Frequency in Windows 10

    Using the High performance or Ultimate performance power plan will also let you always use the highest CPU frequency.

    - I added the frequency via cmd and checked, it's set to 0.

    - I'm on "Best performance" profile of my current power plan called balanced( recommended ) .
    I noticed I only have one Power plan, and I can select a profile with the slider from the bottom power icon next to the clock. Shouldn't I try to unlock the other power plans or something?

    If wanted, you could use an option in the tutorial below to restore the high or ultimate power plan to see if how it works for you.

    Interesting! Thx for the link

    The command for "high performance " failed for me
    "Unable to create a new power scheme
    The power scheme, subgroup or setting specified does not exist."


    But the other two worked, I tried Ultimate performance, and still it throttled...

    I have a Dell Precision 7740 with a Xeon E-2276 M (2.8 GHz, Turbo to 4.7 GHz) with 128 GB RAM.

    I did this for the number crunching I have to do for medical research as well as running Dragon Medical Practice Edition (a previous computer was hanging at times).

    I'm curious if there are any downsides to setting the minimum processor to 75 or even 100%? The laptop has some aggressive cooling fans. Will it cause undue heat or negatively impact the CPU lifespan? Will 50, 75, or 100% minimum performance settings even increase performance? I'm assuming setting it at 100% will make the CPU run at 2.8 GHz constantly and not at the TurboBoost speed of 4.7 GHz?

    Thanks!

    Hello Eric,

    Correct, setting a high min can cause overheating if you don't have good cooling, and will use more energy. It won't hurt to test to see how it runs, but there's really no need to set a high min since it will automatically increase to the max as needed.

    100% max will allow the CPU to run at its highest available GHz as needed.
