Kernel-Power Critical Error

The Kernel-Power Critical error is a warning associated with unexpected system shutdowns, most commonly in power failures. Users can avoid it by restarting their PCs only through usual methods. There also are easily-implemented methods of troubleshooting unexpected shutdowns and the Kernel-Power Critical error without significant computer expertise or requiring third-party services or tools.

All Power to the Computer (or Not)

Although most users aren't in the habit of perusing the Windows Event Viewer for fun, checking error messages after unexpected problems can be a boon. The Kernel-Power Critical error, or Event ID 41, is one of the most commonly-seen and well-understood ones: an alert that the system has experienced an unconventional shutdown and restart. It's common when the PC loses power, such as being unplugged without shutting down first.

Users only should react to the Kernel-Power Critical error as a significant problem if it reoccurs without warning or obviously-preventable cause. In the worst cases, Kernel-Power Critical error and shutdowns can be symptoms of dying hardware. However, changing power settings can resolve many, less-severe scenarios wherein hardware uses too much power for different reasons.

Customize power settings by opening 'Power & sleep' from the Windows search bar. The majority of options related to this problem lie in 'Additional power settings.' For a ready-made solution, users can choose an energy-efficient plan, such as 'Power Saver' or 'Balanced.' More options are available in the 'Change plan settings' and 'Change advanced power settings' windows, such as specifying when to turn off the hard disk after inactivity. Some systems also may show 'On battery' or 'Plugged in' turn off options, which should be on 'Never' for troubleshooting.

Patching Oneself Out of a Power Predicament

As with many other computer problems, a Kernel-Power Critical error also can be due to just out-of-date software. Drivers for hardware should always use the latest updates. Windows includes a user-friendly driver uninstall and update management feature that users can access from the Device Manager. However, most users should download their driver updates straight from the relevant manufacturer or other company after navigating directly to their official website preferentially.

Although users should test most other solutions first, hardware power supply problems can also trace back to an outdated BIOS. Since the BIOS handles the boot sequence before the operating system starts, configuring it poorly or mishandling an update can make the computer unable to boot-up. Users that are sure of the need should go to their motherboard manufacturer's site and follow the provided instructions.

Rarely, a Kernel-Power Critical error may be a side effect of a threat, such as a cryptocurrency-mining Trojan, abusing hardware resources. Reoccurring, excess power usage and shutdowns are issues that all users should resolve as soon as possible. Traditional anti-malware products will remove practically all threats capable of causing these symptoms.

The Kernel-Power Critical error is one of the universal problem events that any PC owner might happen across. Although it can be the last gasp of dying hardware, on average, its source is much less of an expensive problem for fixing, even for a novice.
