Unplugging USB Power cable triggers "Power Surge on the USB Port" warning

I'm having a bizarre issue where simply unplugging the official Lenovo power supply from the orange USB power port causes the laptop to immediately issue the subject warning, along with the detail "A USB device has malfunctioned and exceeded the power limits of its hub port".   This warning pops up every 5 seconds, unless clicked on, where reset/close options do nothing. 

 

Crazy thing is, NOTHING is plugged into any USB port!   Reattaching the power supply does not clear the error.  Only rebooting with the power supply cable connected clears the error.   Remove the power cable, and the error instantly comes back.   All of the USB ports actually work fine, including the USB C port, whether or not this message is active.

 

Maybe it is a hardware issue, but ALL the USB ports actually work fine.  I can't figure how unpluging the power source can trigger a USB power surge when nothing is actually connected and the battery is fully charged.  I've removed/reinstalled the USB Root hub, eXtensible Host Controller, Generic USB Hub, etc., drivers multiple times to no avail.   No errors with any devices are apparent in the device manager.

 

I've seen a lot of issues reported about USB power surges but none like mine.   Anyone have any ideas about this?

Hi GaryOkieB,

 

Welcome to the Community Forums.

 

You can try to disable the prompt via Devie Manager > USB Host Controller  > properties tab then uncheck " "Don't tell me about USB errors" option.

 

You can use Lenovo Vantage to re run diagnotics and check for update drivers.

It may just be Windows error notification issues as what happened in lower version of Windows.

 

Update us how it goes.

 

Regards

Thanks Spidey for the suggestion.    In Device Manager, the Intel USB 3 eXtended Host Controller does not show this option under properties.   (Driver Version 10.0.17134  4/10/2018).   Nor do any of the other USB-related drivers.   The only option shown is to allow computer to turn it off to safe power.   These are the newest drivers.

 

 

I did find an option under general Windows 10 Settings for USB and unchecked "Notify me if there any issues connecting USB devices".

 

Hey, that worked!  Smiley Happy

 

Thanks for pointing out a reasonable workaround to whatever weird hardware/software glitch this may be.

Hi GaryOkieB,

 

Greetings.

 

It's good that you get the idea from the suggestion to disable power notification prompts from the device manager although it is different written on each versions of Windows and helped you resolve this.

 

Please don't hesitate to visit our community at any time.

 

Regards

Thanks for this tip.

 

I had the same issue and resolved it by unticking the option in WIndows 10 Settings > Devices > USB > Notify me if there are issues connecting to USB devices

 

Thanks!

Re: Unplugging USB Power cable triggers "Power Surge on the USB Port" warning

Common, this is not a solution! It is a workaround that may eventually hide a real problem. Why is there such a problem in the first place? Windows must have a reason to report the error and it is most likely a driver or hardware issue. Will/can that be fixed by a firmware/driver update?
