Question about HP Pavilion dv4000 Notebook

Power Surge error message

I repeatedly get the message "Power Surge on Hub Port: A USB device has malfunctioned and exceeded the power limits of its hub port. You should disconnect the device." This is despite the fact that no device is plugged in. It doesn't seem to affect the functionality of the computer as far as I can tell but it is still concerning. Any advice on how to address this?

Once the USB port(s) are disabled what is the repair to bring back USB 2.0 functionality?

    That doesn't return the functionality of the ports

  • eeper May 13, 2008

    In order to turn off the error message the Microsoft solution is to diable the ports which reverts them to USB 1.0 so they say but there is not functionality. If I try a system restore am I running a data loss risk? Should I enable the ports first?

  • eeper May 13, 2008

    Actually I have tried this and it didn't work.

  • eeper May 13, 2008

    yes, I tried that when the problem first appeared about a week ago. The error message actually says if you don't click reset port (which I did but it didn't matter) functionality will be lost. So the question is what does that error message trigger and how do you turn it back on or off?

  • eeper May 13, 2008

    There is no functionality whether you plug in a mouse, keyboard, jump or anything. Though you can see the light in the mouse so there is AC poer but no communication

Right click START ,choose properties,choose taskbar then customize ,and select power surge...and select ALWAYS HIDE

this way you get rid of the pop-up message and just don't worry about it

This is just some error with microsoft and it shouldn't be a big deal at all.

Let me know if you want further information on this, thanks

    wait, your ports aren't working now? the first post suggests that everything is working.

  • Benjamin Patri
    Benjamin Patri May 13, 2008

    don't disable the ports, what you can try is a system restore which can be done within your control panel

  • Benjamin Patri
    Benjamin Patri May 13, 2008

    you should be able to then go to performance and maintenance and do a restore to yesterday or one of the past days and that should stop the error. let me know how this goes

  • Benjamin Patri
    Benjamin Patri May 13, 2008

    you don't lose any data with a system restore. The computer keeps all documents and anything like them made after the restore point and the whole process is reversible.

  • Benjamin Patri
    Benjamin Patri May 13, 2008

    you already tried a system restore?

  • Benjamin Patri
    Benjamin Patri May 13, 2008

    alright with the new info that you provided

    either you have an electrical short in one of the plugs or sockets or your motherboard could be going bad.

    One thing you could try is upgrading the bios on the computer and see if that helps at all. you should be able to do this from the manufacturer's website

  • Benjamin Patri
    Benjamin Patri May 19, 2008

    did you try upgrading your bios, if not please do so and let me know how that goes, If you do it and it doesn't work, then your motherboard is probably going to need to be replaced. Let me know of any further help that you need. thanks and good luck

Power Surge on Hub Port


Some USB devices draw excessive power from the USB port, especially USB scanners. When this happens you need a powered USB hub, connect this to your computer's USB port and connect the USB device into the powered USB hub, you should not have any further error power surge problems.

Power surge on hub port


Try this to find out which one of your components has an issue. Turn off your machine then unplug all of your USB cables. Turn your machine back on and plug in one of your USB cables. Verify the component you just plugged in works correctly and if it does plug in another cable and verify that component is working. Continue these steps until you have the one component that displays the error you have seen. That component is most likely the cause of your issue and should be replaced.

Good luck, Greased.

Power Surge error message


Hello,

 

 

I guess that this could be your error message:

"Error message when you wake up a Windows XP-based computer from hibernation or from standby: "Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port"

 

If it is the case, please try below solution:

 

SYMPTOMS

 

When you wake up a Microsoft Windows XP-based computer from hibernation or from standby, you may receive the following error message:

 

Power Surge on Hub Port: A USB Device has exceeded the power limits of its hub port. This error message is displayed even if there are no USB devices connected to the computer.   WORKAROUND loadTOCNode(1, 'workaround'); To work around this issue, disable the USB 2.0-enhanced host controller.

Note When you disable the USB 2.0-enhanced host controller, you lose USB 2.0 functionality. That is, you revert to USB 1.1 functionality.

To disable the USB 2.0-enhanced host controller, follow these steps: 1. Right-click My Computer, and then click Manage. 2. Under Computer Management (Local), click Device Manager. 3. In the Device Manager pane, expand Universal Serial Bus controllers. 4. Right-click the USB 2.0-enhanced host controller, and then click Disable.

Note The name of the USB 2.0-enhanced host controller may vary. 5. When you receive the confirmation message, click Yes. 6.

Close Device Manager.

 

 

I hope that this should resolve the issue for you.

 

 

Please let me know the result. 

 

you can mail me at thumuvikram@rediffmail.com for any further assistance on this issue.

 

I'll be glad to help you.
