Power surge problem on laptop with Windows Pro SP3

Hello, everyone!

I have a computer problem that scares me a bit. I get this error message that says, "Power surge on hub port and it won’t go away. A USB device has exceeded the power limits of its hub port. For assistance in solving this problem, click this message." This pops up even when there is no USB device connected.

I have just installed Windows Pro Service Pack 3 on my laptop, which also contains a wireless card. Unfortunately, I don’t have any inkling how to access this card.

Any suggestion on how to solve this would be greatly appreciated. Thanks!

There are several reasons why your laptop may receive error messages, but if you already tried to do as instructed on the message that comes up after the error “Power surge on hub port and it won’t go away. A USB device has exceeded the power limits of its hub port. For assistance in solving this problem, click this message” and the issue is still persisting, despite the fact that you don’t have any USB devices connected to your laptop, then it can only because of these things:

  1. Your motherboard could be using too much power in its USB controller circuitry which is not good.
  2. You may have an electrical short in either one of the plugs or the sockets.

Either way, you will have to bring your laptop to a repair center for them to check if your motherboard needs to be replaced already, or if you need to change one of your plugs or sockets.

Have you checked your computer for viruses and ran a scan for such infections as well as malwares? This could be a false warning created by these infections since it keeps on coming up even if the port is not being used. USB devices are created through a standard therefore whatever power requirements the USB has that is what will be followed by manufacturers. Such a warning is also not common and has not been heard of about hence it most likely is a bogus warning meant to trick you into buying something or meant to just make fun of you and your thinking.
