Fix Power Surge on the USB Port Error in Windows 11/10
Have you ever plugged a USB flash drive, external hard drive, keyboard, or another device into your computer and suddenly received a “Power Surge on the USB Port” warning?
The message usually means that a connected USB device has exceeded the power limits of the port or that Windows has detected an electrical problem with the connection. Common causes include a faulty USB cable, a damaged device, an overloaded USB hub, outdated drivers, or a problem with the computer’s USB port.
In this guide, I will explain how to fix the Power Surge on the USB Port error in Windows 10 and Windows 11.
Fix Power Surge on the USB Port Error (Windows)

The quickest way to troubleshoot this error is to disconnect the affected USB device, restart your computer, and test the device with another compatible USB port and cable. If the warning continues, check your USB drivers, power settings, and available power supply.
Before trying advanced fixes, disconnect any device that triggers the warning.
If you notice a burning smell, unusual heat, bent connectors, or visible damage, stop using that port or device.
Don’t try to bypass the computer’s USB power protection.
Step 1: Disconnect the USB Device and Restart Your Computer
Start with the simplest fix. Sometimes, Windows detects a temporary USB connection problem and displays the warning even after the original device has been disconnected.
Unplug the USB device that triggered the error. If you’re using a USB hub, disconnect the hub from your computer and remove its connected devices.
If the warning is still visible, select Reset if Windows offers that option. Save your work, open the Start menu, select the Power button, and click Restart.
Wait for Windows to load completely before reconnecting the device. Connect only the affected device first so you can determine whether it triggers the warning again.
If the error disappears, reconnect your other USB devices one at a time. This helps identify whether a particular accessory or combination of devices is causing the problem.
If the warning returns immediately, disconnect the affected device and continue to the next step.
Step 2: Try Another USB Port and Cable
A damaged USB port or faulty cable can cause power-related errors. Testing another port helps you determine whether the issue is limited to one connection.
First, unplug the affected device and inspect its USB connector and cable. Look for bent pins, frayed wires, loose connectors, or other visible damage. Never insert metal objects into a USB port to clean it.
Next, connect the device to another USB port on your computer. If you’re using a desktop PC, try a rear motherboard USB port instead of a front-panel port.
If the device uses a detachable cable, try a compatible replacement cable that supports the device’s power and data requirements.
Check whether the warning appears again. If the device works through another port, the original port or its internal connection may be faulty.
If multiple devices trigger the same warning on one port, stop using that port until the problem is investigated. If the warning follows the device across several ports, the device or cable may be responsible.
Step 3: Disconnect Other USB Devices
Connecting several USB devices through the same hub can sometimes exceed the available power budget, especially when the devices draw power directly from the computer.
For example, an external hard drive, webcam, USB lighting accessory, and other peripherals may compete for the available power when connected through one unpowered hub.
Disconnect unnecessary USB accessories, leaving only essential devices connected. Then reconnect the device that triggered the error.
If it works normally, reconnect the other accessories one at a time to identify whether the problem occurs when a particular device or combination is connected.
For power-hungry accessories, use the manufacturer’s recommended power adapter. You can also try a compatible powered USB hub with its own power supply, provided the device supports that setup.
A powered hub can help when the computer’s USB port cannot supply enough power, but it won’t repair a damaged cable, faulty device, or defective USB port.
Step 4: Run the Hardware Troubleshooter
Windows troubleshooting tools may help identify common hardware or device problems. The traditional Hardware and Devices troubleshooter isn’t available as a standard option on every Windows 10 or Windows 11 installation, so don’t worry if you can’t find it.
Open Settings > System > Troubleshoot in Windows 11 and check the available troubleshooters. In Windows 10, open Settings > Update & Security > Troubleshoot.
If the Hardware and Devices troubleshooter is available, run it and follow the on-screen instructions.
If it isn’t listed, open the Get Help app from the Start menu and search for hardware or device troubleshooting guidance.
Follow any recommended steps and restart your computer if prompted. Then reconnect the USB device and check whether the warning returns.
If Windows doesn’t identify a problem or the error continues, move on to the USB driver checks.
Step 5: Reinstall the USB Controllers
Corrupted or malfunctioning USB controller drivers can interfere with communication between Windows and connected devices. Reinstalling the relevant controller can help resolve driver-related issues.
Disconnect the affected USB device. Press Windows + X and select Device Manager.
Find and expand Universal Serial Bus controllers. You’ll see entries such as USB Root Hub, USB Host Controller, or USB Composite Device, depending on your computer.
Right-click the relevant USB controller or hub and select Uninstall device. If you’re unsure which entry is responsible, avoid uninstalling every device at once. Removing all USB controllers can temporarily disable USB-connected keyboards, mice, and other accessories.
Restart your computer. Windows will generally detect the hardware and reinstall the necessary drivers automatically.
After Windows loads, reconnect the affected device and check whether the error has disappeared.
If the problem continues, visit your computer manufacturer’s official support website and check for compatible chipset and USB controller drivers.
Step 6: Update Your USB and Chipset Drivers
Outdated chipset or USB drivers can cause hardware compatibility problems. Installing the correct drivers from your computer manufacturer may help if the error began after a Windows update or hardware change.
Open Device Manager again and expand Universal Serial Bus controllers. Right-click the relevant controller and select Update driver.
Choose Search automatically for drivers and follow any instructions.
Keep in mind that Windows may report that the best driver is already installed even when the manufacturer’s website has a newer compatible version.
To check for manufacturer updates, identify your computer model and visit its official support page. Look for chipset, USB, or system drivers specifically designed for your Windows version.
Download and install only compatible packages. Restart your computer if requested, then test the USB device again.
If the error started immediately after a driver update, check whether the Roll Back Driver option is available in the device’s Properties window. Use it only when there’s a clear connection between the update and the problem.
Step 7: Check USB Power Management Settings
Windows can manage USB power to reduce energy consumption. Although these settings are not the most common cause of an actual overcurrent warning, checking them may help if your USB device repeatedly disconnects or behaves incorrectly.
Press Windows + R, type control, and press Enter to open Control Panel.
Select Hardware and Sound > Power Options. Click Change plan settings next to your active power plan, then select Change advanced power settings.
If the USB settings > USB selective suspend setting option is available, you can temporarily disable USB selective suspend to test whether it helps. Apply the change and restart your computer.
On laptops, disabling this feature may increase power consumption. If it doesn’t help, return to the same menu and restore the previous setting.
Remember that changing power management settings cannot fix a physically damaged port or a USB device that draws excessive current.
Step 8: Check for BIOS and Firmware Updates
Your computer’s BIOS or UEFI firmware helps manage communication between the operating system and hardware. In some cases, a manufacturer-provided firmware update may resolve USB compatibility or power-management issues.
First, identify your computer’s manufacturer and exact model. Visit its official support website and check whether a BIOS or UEFI update is available for your system.
Read the update instructions carefully before installing anything. A BIOS update is different from a normal Windows driver update, and interrupting the process can prevent your computer from starting correctly.
Connect your laptop to its charger and make sure its battery has sufficient power. For a desktop, use a reliable power source and follow the manufacturer’s precautions.
Install the update only if it applies to your computer and addresses a relevant issue. Restart your PC and test the USB port again.
If the warning persists, continue to the final troubleshooting step.
Step 9: Check for a Faulty USB Port or Device
If you’ve tried the previous methods and the warning continues, you may be dealing with a hardware problem rather than a Windows setting.
Disconnect the affected device and test it on another compatible computer, if available. If it triggers the same warning on multiple systems, the device or cable may be defective.
If several known-good USB devices trigger the error on the same computer port, the port, internal USB hub, front-panel connection, or motherboard circuitry may be faulty. A warning that appears even when nothing is connected can also indicate a hardware problem.
Stop using any port that appears damaged or repeatedly triggers the warning. Don’t keep reconnecting a device to test whether the error goes away, and never attempt to bypass overcurrent protection.
Contact your computer manufacturer’s support team or a qualified repair technician if the problem persists.
They can check the port and related hardware to determine whether repair or replacement is necessary.
