How to Troubleshoot a “Power Surge on USB Port” Error on Windows 10:
If you see the “Power Surge on USB Port” notification, don’t panic right away when you’re using a USB device on Windows 10. The term “surge” may sound annoying, but it doesn’t mean that your PC or laptop has been damaged in some way (although you can’t rule it out).
This error usually appears when the maximum power limit of the USB port is exceeded in some way. This is unusual, but not impossible – for example, some devices (including USB hard drives) use a lot of energy. If you see a “Power Surge on USB Port” error on Windows 10, here’s what you’ll need to do to fix it.
What is the reason for the “Power Surge on USB Port” error on Windows 10?
If Windows displays a “Power Surge on USB Port” error, you can generally assume that the power demand of any connected USB peripherals has exceeded the maximum power capacity on the USB port you are using.
For example, some USB hard drive enclosures are supplied with a double-headed USB cable. The purpose is to connect the drive to two separate USB ports, spreading the power and data load on the two ports and giving enough power to operate the drive.
Although this is not an ideal scenario. Poorly constructed enclosures (with badly designed circuit boards) can spread the power demand unevenly at each port. A similar message also appears when any other type of cheap, poorly made USB device is connected to your PC.
If Windows detects that too much power has been drawn from the USB port, it will deactivate it in an attempt to protect your PC from damage. Unfortunately, there is no guarantee that the loss has not already occurred after increasing USB power. You will need to investigate the problem and check your USB port by following the steps below.
Disconnect your hardware
If Windows 10 detects a power surge on the USB port you are using, Windows will automatically disable the port. In theory, this should prevent an increase in power and protect your PC or connected USB device from any further damage, but it is not guaranteed.
If this happens, you should immediately disconnect the device by removing the USB cable from the affected port. It is important to do this as soon as you see the message, as leaving the connected device can cause long term damage. As long as the device is not drawing a large amount of power, however, you can avoid damage.
Unfortunately, this does not cause an error at first, but it will allow you to resume using your PC (if it is unpublished). You will need to consider whether the device is functioning properly before using it to reconnect and use the device.
Restore USB Controller Drive in Device Manager
You should never connect any device (USB or otherwise) to your PC if you are unsure whether it is safe to use. It is important to consider the quality and expected power consumption of the USB devices you use, as high power devices from cheap sources can (and most likely will) cause harmful power increases.
If you are sure that the USB device is safe to use, and when you reconnect it, it does not immediately cause a power surge, you should consider reinstalling the USB controller drivers for your motherboard. May be required. A faulty USB controller driver may produce a power surge report due to such a malfunction.
- To do this, right-click on the Start menu and select device Manager.
- In the Device Manager window, select the arrow Universal Serial Bus controllers Category to see available options. For each USB device listed, right-click and select Uninstall Tip To remove installed drivers.
After removing the USB controller drivers, you can check Windows Update or your motherboard manufacturer for the latest up-to-date drivers and install them manually. Alternatively, restart your PC at this point – when you restart Windows Update will automatically discover (and install) any available drivers.
Run hardware and device troubleshooting tools
Windows 10 includes a built-in troubleshooter that can identify issues with your PC and recommend possible fixes. While it cannot fix damaged hardware, it can identify potential causes for a power surge message, such as a missing driver or a broken device.
The hardware and device troubleshooting tool was originally available in the Windows Settings menu, but is now hidden from view. To use it, you will need to use Windows powershell.
- To open a new PowerShell window, right-click on the Start menu and select Windows PowerShell (Administration).
- Type msdt.exe -id DeviceDiagnostic Choose more Enter In the PowerShell window to run the hardware and equipment troubleshooter.
- In Hardware & Tools Window, select next To start checking your PC for hardware issues. It will take some time to complete.
Windows will check your settings, USB ports, and any connected devices for potential problems. If the hardware and devices tool can fix any problems automatically, it will do so. Otherwise, it will provide a list of recommendations at the end of the scanning process, so look for any additional on-screen instructions.
Use a powered usb hub
If you are still troubled by the “Power Surge on USB Port” error message, you may need to consider investing in a powered USB hub. Such an external hub allows you to securely connect high-powered devices to your PC’s USB port, but if the hub operates separately, protecting your USB port from damage.
This is only true, however, if you select a respected manufacturer such as Dell, Anchor, or TP-Link. If the hub is unbranded or comes from an unknown source, it risks like other cheap USB devices. Connecting it to your USB port can cause damage, especially if it causes a surge (as a result of the same problem).
If the hub is genuine, well built, and has a good quality power supply, it will help prevent possible power surge caused by USB devices connected to your PC’s USB port. If the port and USB device are not already damaged, it should stop the “Power Surge on USB Port” message and may allow you to use it.
However, damage to your PC cannot prevent the possibility of other lightning blows (such as lightning strikes). You may need to consider adding one surge protector To protect your PC setup from these additional risks.
Protect your pc against hardware damage
If you are lucky, an abusive USB device will not cause damage to your USB ports the first time it bounces, but that does not mean that it will not cause damage in the long term. To protect your PC and devices from damage, a powered USB hub is necessary to ensure that the hardware you are using has enough power to work.
If you are still seeing a “power surge on USB port” error with the hub, then you need to watch your hardware closely. For example, if your USB drive not detected, May be the cause of insufficient power, or USB port may not work. If you still have problems, it may be time Change your pc or hardware With new components.
