Fix – Kernel Power 41 Error

Solution 1 – Update your drivers

Kernel power 41 error is sometimes caused by outdated drivers, and if you want to fix it, make sure that you have the latest drivers installed. In most cases, this issue is caused by your audio driver, so be sure to update it first. If updating your audio driver doesn’t resolve this issue, proceed to update other drivers on your computer.

If you do not have the necessary computer skills to update/fix the drivers manually, we strongly suggest to do it automatically by using Tweakbit’s Driver Updater tool. This tool is approved by Microsoft and Norton Antivirus. After several tests, our team concluded that this is the best-automatized solution. Below you can find a quick guide how to do it.

  1. Download and install TweakBit Driver Updater
  2. driver updater starting windowOnce installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.
  3. driver updater diagnozingUpon scan completion, you get a report on all problem drivers found on your PC. Review the list and see if you want to update each driver individually or all at once. To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.

    Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

Solution 2 – Disable duplicate audio drivers

We already mentioned that kernel power 41 error can be caused by your audio driver, so make sure that you check Device Manager for any duplicate driver entries. To do that, follow these steps:

  1. Press Windows Key + X and choose Device Manager from the menu.
    device-manager
  2. When Device Manager opens, locate your audio drivers in Sound, video and game controllers section.
  3. If you see duplicate entries, right-click one of those duplicates and choose Disable from the menu.
    device-manager-disable

Even if you don’t have duplicate audio drivers, you can try disabling one of the audio drivers that you have on the list. Users have reported that the issue was resolved after disabling ATI High Definition Audio Device from Device Manager. Even if you don’t have ATI High Definition Audio Device installed, you can try disabling any audio device that isn’t High Definition Audio Device.


Solution 3 – Uninstall your antivirus

Certain antivirus software, such as AVG, can cause kernel power 41 error on your Windows 10 device. If you have AVG antivirus installed, try to temporarily uninstall it and see if the issue is resolved. If the problem still persists, you might want to consider switching to a different antivirus software.

Best antiviruses at the moment are Bitdefender, BullGuard, and Panda. We strongly recommend Bitdefender for its highly rated features that will keep your PC safe and optimized.


Solution 4 – Change your power settings

Kernel power 41 error can be caused by your power settings, so it might be best that you change some of those settings. To do that, follow these steps:

  1. Press Windows Key + S, type Power Options and choose Power Options from the menu.
    power-options
  2. When Power Options window opens, find your current plan and click on Change plan settings.
    change-plan-settings
  3. Now click on Change advanced power settings.
    changed-advanced-power-settings

    turn-off-hard-disk-after
  5. Find the Sleep section and set the sleep timer to 0 in order to turn it off.
  6. Click Apply and OK to save the changes.

Solution 5 – Turn off Fast Startup

If you have problems with Kernel power 41, you should know that this issue can be caused by the Fast Startup option. In order to fix this problem, it’s advised that you turn off Fast Startup feature, and you can do that by following these steps:

  1. Open Power Options.
  2. When Power Options window opens, click on Choose what the power button does.
    power-options
  3. Click on Change settings that are currently unavailable.
    power-options-2
  4. Scroll down to the Shutdown settings section.
  5. Locate Turn on fast startup (recommended) and uncheck it.

Solution 6 – Update your BIOS

In order to update BIOS, you need to visit your motherboard manufacturer’s website and download the latest version of BIOS. Before you start the update, make sure that you read the instruction manual carefully in order to avoid causing permanent damage to your computer. If you don’t know how to update BIOS on your own, please ask an expert to do it for you.


Solution 7 – Check your hardware

Kernel power 41 error can also be related to your hardware, and if you’ve encountered a random restart on Windows 10, it might be due to a hardware problem. Users have reported that after replacing their motherboard or power supply unit, the issue with kernel power 41 was completely resolved. Few users have also reported that their issue was caused due to RAM, so you might want to consider replacing your RAM modules. If your computer is still under warranty, we strongly advise you to take it to the repair shop and have them check your hardware.


Solution 8 – Uninstall recent updates

We all know how Windows 10 mandatory updates can bring us a world of pain. Maybe the intentions were good, but the end results are preposterous for some users. Some of them reported that problems started with the latest Windows Updates that rendered the system completely unusable.

Now, since there’s no the way to avoid updates completely (it seems that the Windows Update service restarts on its own even if you disabled it), you can at least relieve yourself from the recent updates by uninstalling them from the system.

Here’s how to do it in a few simple steps:

  1. Press Windows key + I to open the Settings app.
  2. Select Update & security.
  3. Click on View installed update history.
  4. Choose to Uninstall updates.
  5. Uninstall all recent updates and restart your PC.

Solution 9 – Disable Auto-restart in the Advanced System settings

This workaround comes into play only and only if you’re 100% sure that your hardware is spot on. The majority of affected users resolved the issue by replacing some of the key hardware components, with the special focus on the power supply and CPU. Therefore, if you’re completely certain that everything is bread and butter concerning the hardware, but the sudden shutdowns with the same error reoccur frequently, you can try and disable the error-inflicted auto-restart.

This feature is there to restart and create an automatic report in case something goes awry. By disabling it, you’ll at least avoid sudden restarts. Here’s how to do it in Windows 10:

  1. In the Windows Search bar, type Advanced settings and open ”View advanced system settings”.
  2. Select the Advanced tab.
  3. Click Settings under the Startup and Recovery section.
  4. Uncheck the ”Automatically restart” box and confirm changes.

We also strongly recommend you to download this tool (100% safe and tested by us) to fix various PC problems, such as hardware failure, but also file loss and malware.

These are some of the most common solutions for kernel power 41 error, so make sure that you try them out, and let us know if our solutions have been helpful to you.
