How to fix Kernel-Power error 41 in Windows 11

If your Windows 11 computer shuts down unexpectedly or restarts without warning, you may encounter the Kernel-Power error 41This problem is more common than it seems and is usually related to failures in the power supply or in the computer hardware.

In this article we explain in depth what this error is (which occurs apparently randomly, even when the computer is idle) and how to solve it with different effective methods. The key is to identify whether the problem is due to the power supply, Windows power settings, or a hardware failure.

What is Kernel-Power Error 41?

The error Kernel Power 41 It is a critical message that appears in the Windows Event Viewer when the system restarts without shutting down properly. This may be because the PC stops responding, freezes, or loses power unexpectedly. When this alert message appears on your computer, it means that a problem has occurred. forced closure of the system without a clean shutdown.

These are some of the most common causes of this problem:

• Inadequate power supply: If the PSU (power supply unit) does not provide enough power to the components, the system may shut down suddenly.
• Outdated drivers: An old or incompatible driver, especially from the Graphic card o chipset, may cause power failures.
• Windows power options misconfigured: Some settings, such as the quick start, can generate conflicts.
• Hardware issues: Overheating, failures in the RAM or faulty connections can cause unexpected reboots.

How to check the error in the Event Viewer

 

Before applying any solution, it is important to confirm if you are actually experiencing Kernel-Power 41 error. To do this, you can Check the Event Viewer Windows by following these steps:

1. First we use the keyboard shortcut Windows + X to select the Events viewer.
2. In the left panel, we expand "Windows logs".
3. Then we select "System".
4. There, under the Event ID column, we search events with the code 41
5. If the error appears repeatedly, it is most likely caused by Kernel-Power error 41.

Possible solutions to Kernel-Power error 41

Once the problem has been identified, let's see what methods exist to solve the Kernel-Power 41 error in Windows 11:

1. Check the power supply (PSU)

One of the first elements to analyze is the power supplyIf the PSU does not provide enough power or is faulty, the system may shut down unexpectedly.

To check if the power supply is the problem you can do this:

• Check that the PSU has enough capacity to power your hardware. If you have installed a new graphics card or added components, verify that the power supply is adequate.
• If you have the possibility, try another power supply to see if the problem persists.
• If the PSU has been in use for several years, it may be failing and you need to replace it.

2. Update system drivers

The Controllers Drivers are a key element for system stability. An outdated or corrupted driver can cause unexpected shutdowns and result in the Kernel-Power 41 error. That's why updating all essential drivers is a recommended solution. You can do it like this:

1. Press Windows + X and select "Device administrator".
2. Expand the most relevant categories, such as Display adapters, sound drivers y Chipset drivers.
3. Right click on each device and select "Update driver".
4. Choose the option «Search automatically for updated driver software».
5. Restart your PC and check if the problem persists.

3. Disable fast startup

Windows includes a feature called quick start which helps to reduce system boot time, but in some cases it can cause conflicts with hardware (and cause, among other things, the Kernel-Power error 41). To disable it, do the following:

1. Open the Control panel and go to "Energy options".
2. Click on «Choose what the power buttons do».
3. Then select "Change settings currently unavailable".
4. Uncheck the box "Enable fast startup (recommended)".
5. Save the changes and restart the computer.

4. Check the power settings

Some power options may be causing system instability. Here's what to do to optimize your settings:

1. Go to Control Panel.
2. Choose "Energy options".
3. Then access "Change plan settings".
4. Click on "Change advanced power settings".
5. Modify the following settings:
   • In the section HDD, establishes «Turn off hard drive after» en Never.
   • In the section Lay off, configure «Suspend after» en Never.
6. Save the changes and reboot the system.

5. Check RAM and temperature

If your RAM is faulty or the system is overheating, unexpected reboots may occur. To check these items we have some external resources that can be very useful:

• MemTest86 to check the RAM for errors.
• SpeedFan to monitor CPU and GPU temperatures.

Apart from this, it is worth checking that the fans are working properly and that there is no accumulation of dust on the heatsink.

6. Update BIOS

Un old firmware in the motherboard BIOS can cause hardware incompatibilities and cause unexpected reboots. To update the BIOS you can do the following:

1. Visit your motherboard manufacturer's website.
2. Download the latest BIOS version and follow the update instructions.
3. Apply the changes and reboot the system.

7. Reset or reinstall Windows

If none of the above solutions work, the problem could be with the operating system itself. You can reset windows without losing your files or performing a clean installation:

1. Go to Configuration.
2. Then go to “Update & Security”.
3. Then select “Recovery”.
4. Next go to “Reset this PC” and choose the option to keep your files.

If the problem persists, you can opt for a completely clean installation from a USB with Windows.

Once these solutions have been applied, Kernel-Power error 41 should stop appearingIdentifying the exact cause may require several tests, but with patience and the right methods, it is possible to stabilize the system and avoid unexpected outages.
