    CPU processor stuck at 22% usage but Battery/Adapter does not have any issue


    Hi,


    Lately, I have been facing this issue that my processor does not run at its usual speed. It works totally fine for a few moments after I wake it from sleep but after 1-2 minutes, the processor cannot clock above 0.48 GHz while the base speed is 2.2 GHz. This makes my laptop very laggy and sometimes even simple processes, like using word docs, excel can't be performed.


    Things I have tried based on the other threads that I could find here:


    1. Running a boot time hardware diagnostics for understanding if the battery, adapter or processor is at fault. But I could not find any issue.

    2. Switched battery performance to High Performance, still to no avail.

    3. Used Intel's Diagnostic tool to fully check different issues with the processor, but nothing was found. All tests were passed the system.

    4. Reinstalled OS to eliminate any malware issue.


    Please help me in this regard.


    A few additional information that I can think of that could be relevant.

    - The battery and the adapter both are manufacturer's build. I haven't replaced them since I bought the laptop.

    - I first experienced this issue while playing a game. The FPS suddenly dropped to around 10-15 and the laptop is never the same since.

    - I also experience problems with audio of the laptop while using it for a local mp3 or video file.



    Laptop specifications:

    OS: Windows 10 Pro

    RAM: 8 GB DDR3

    Processor: IntelR CoreTM i5-5200U CPU @ 2.2 GHz

    Cores: Dual

    Logical units: 4


    I am also attaching a screenshot of the Task Manager highlighting this issue..

  2. Laptop CPU processor stuck at 22%

    So that's what did it. After installing a Dell branded AC adapter the battery is able to fully charge and the CPU isn't stuck at 22%.

    Thanks every for your suggestions.

  3. Laptop CPU processor stuck at 22%

    All tests pass green.

    I checked the BIOS and the adapter status is unknown. The battery status stated it was charging as well as excellent condition.

    Booted into windows. Status was plugged in but not charging.

    Ran the power troubleshooter. Stated it fixed some issues but the problem still remained.

    Discovered something odd with the battery. I unplugged the adapter and ran a torture test with Prime95. Task Manager stated the cpu usage was at 100%. So I plugged the AC adapter back in. The CPU 22% problem came back, but the battery status was stating
    plugged in and charging.

    I'll go through the manual calibration process and see how it performs tomorrow.

    CPU processor stuck at 22% usage but Battery/Adapter does not have any issue

    CPU Usage limited to 22%?

    So if I do get a 97w charger it'll fix the CPU Usage stuck at 22%? Keep in mind, this only happens when I'm plugged in (on any power mode) and not when I'm on battery, so is the system doing something to preserve battery life?
