Part 3: How to Fix Power Surge on the USB Port?

Now let's explore the solutions. We have four easy methods to resolve USB port power surges. These tips are simple and effective. Let's begin addressing those USB port issues, step by step!

Way 1: Run the Hardware Troubleshooter

If Windows alerts you about a sudden power surge on a USB port, don't panic. Instead, use the built-in Windows Hardware Troubleshooter to address the issue. This hidden tool will diagnose the issue and hopefully resolve it with simple automated repair steps you can follow.

These are your quick steps:

  • Open a Command Prompt window as an administrator by searching for CMD, right clicking it in the search results, and selecting “Run as administrator.”
  • Type in the command “msdt.exe /id devicediagnostic” and hit Enter to launch the Hardware Troubleshooter.

    run the hardware troubleshooter
  • A popup will appear - click “Next” to let Windows start investigating the USB power surge. Follow any repair prompts shown.
  • When the troubleshooting is finished, check if your USB device and port are functioning normally again.
  • You may need to restart your computer for changes to fully apply.

The Hardware Troubleshooter takes over a deep scan of your Windows system and automatically corrects common errors tied to USB power issues. Let it quickly handle any easy solutions and restore your USB connection!

Way 2: Update all the USB Controller Drivers

If using the Hardware Troubleshooter doesn’t stop your USB port reporting power surges, try updating your motherboard’s USB drivers. An outdated, incompatible, or corrupted driver can trigger this error.

You have two options to update:

  • Manual Update: Go to your motherboard OEM’s website, like ASUS, MSI, or Gigabyte. Search for your exact model and see if they have a newer USB driver available to download and install. This ensures compatibility with your hardware.
  • Automatic Update: Use free driver update software to scan your PC and pinpoint any outdated drivers. Top tools like Driver Booster can then download the latest driver versions directly from manufacturers and install them for you with just a click. Much easier!

Updating to the most recent USB drivers can often resolve quirky port power issues and communication errors with connected devices.

Be sure to restart your PC afterwards to complete the installation. This should stop unexpected power surges and let your USB port function reliably again. Try connecting your USB device again now.

Way 3: Disconnect the Hardware

If updating drivers does not stop the power surges, take the precaution Windows recommends - temporarily disconnect everything.

Follow these safe steps:

  • Unplug all USB devices, peripherals, and cables connected to the affected USB port and computer to fully isolate the port. This includes flash drives, printers, phones, and external hard drives.
  • Click the "Reset" button on the Windows power surge notification to clear the error alert.
  • Restart your computer to fully reset the USB controller and port. This gives a fresh start.
  • Carefully reconnect only one peripheral to test if the power surge persists. Repeat with other devices one by one.

After the restart, you can pinpoint what device, if any, may be specifically overloading the port by methodically testing each one. This helps troubleshoot if the issue lies with your PC or your USB gadget while protecting both. Monitor if the power warning appears again over time.

Way 4: Use a Powered USB Hub

If disconnecting all devices doesn’t stop the power surge alerts, the USB port itself may be damaged or improperly providing enough power. An easy solution is to add an external powered USB hub. A hub expands your number of USB ports, letting you connect multiple devices. More importantly, a powered hub has its own separate power adapter. This draws current directly from a wall socket rather than sapping electricity from your computer’s USB port.

The independent power supply thus stabilizes voltage and regulates amperage available to each connected device. This prevents power fluctuations or drops. It also avoids any one device trying to draw too much wattage from the hub or host PC port behind it. Choose a reputable brand like Anker, Sabrent, or TP-Link for reliable, UL-certified safe hubs with sufficient wattage for your needs. Connect the problematic USB device requiring more juice to the new powered hub instead to resolve surge errors for good. Just be sure to use the wall adapter! Adding an independent power source for needy USB gadgets easily prevents damaging power surges on your PC while keeping data flowing.

Part 4: Frequently Asked Questions

Q: How do I remove power surge from hub port message?

Ans: Unplug the USB hub and connected devices. Restart your computer to reset the USB ports. Ensure you are using a powered hub with its own wall adapter to supply adequate, stable power.

Q: What causes a power surge on my USB port when there are no connected devices?
