Power spike on USB port Charge issues or damage possible
Power spike on USB port Charge issues or damage possible
I was just focusing on my own tasks in a Discord chat when suddenly the Windows 10 alert sounded whenever I unplugged a USB device. It repeated several times. On my screen, there was an error notification at the bottom right (it wasn’t in my recent list). The message said "USB Power Surge from Unknown USB Device." My mouse and keyboard stopped working, even though they were connected to a USB hub. I suspected the hub might be the issue. After removing it, I tried using other USB ports—Logitech G933, Zowie Mouse, keyboard, Bluetooth adapter, and Xbox One controller. Still, the problem persisted, and I couldn’t identify the cause. Now I’m forcing my mouse and keyboard into the front two ports because the rear ones don’t respond. I considered a motherboard fault, but I want to avoid opening the computer unless necessary. I’m hoping for advice and want to know if others have faced the same problem. I really need this for school work, so fixing it quickly would be best. Thanks!
I have a budget motherboard in comparison to the rest of my system, which makes it entirely feasible. I'm praying it works out.
If it reached the CPU, would I still be able to start my PC as before? EDIT: I’m not sure what you meant by “comming.” I’ve attempted that. Sadly, removing one driver often causes keyboard and mouse issues, and I can’t remove the rest. I don’t know how to fix this problem.
Sure, I don't understand either. It completely disables all USB connections.
Sorry, I misunderstood. It was my mistake. The messages kept coming without stopping. I had to remove all USB devices for it to cease. It was quite unsettling, but I finally fixed it. I found an update for Windows and installed it, which helped uninstall the drivers. Restarting the computer resolved the issues. It’s still early to confirm, but everything seems to be working now. Thanks for your support!
I just finished more decluttering and removed items I don’t really need. Now I’m back to working without a USB hub. I won’t be using it again. I don’t have any plans for my computer anymore.
USB standards originally supported drawing up to 500mA, which translates to a peak of around 2.5 watts at 5V. USB 2.0 maintained the same restriction. Later updates introduced features for battery charging, permitting higher currents—up to 1.5A (7.5W) during data transfer and up to 5A otherwise. Not all USB 2.0 devices could handle such power levels. Additionally, the Micro USB connector is limited to 2.1A (10.5W), making it the upper limit for charging phones using 5V.
