PAGE_FAULT_IN_NONPAGED_AREA error after installing new 3900

just hooked up a new 3900 received yesterday to a new computer, HP ENVY. I now have a PAGE_FAULT_IN_NONPAGED_AREA (dlkmd.sys) error and the computer will not boot. Seems there is an issue with the 3900 that caused this. any suggestions to get computer to boot? assume Plugable has to be replaced?

Hi Joe,

Thanks for posting. It seems like the DisplayLink drivers for your docking station are causing the system to reboot. The first step would be to clean the DisplayLink drivers from your system while in safe mode to get the system running normally. I see that you have already reached out to us via our support ticket system, so I will continue to support you directly from there. For anyone else following the thread, those steps are:

  1. Disconnect the dock from the computer and please remove the power cable from the dock so it turns off completely.

  2. Uninstall the DisplayLink Core software from Control Panel->Programs. Don’t worry if this fails, just move onto the next step

  3. Download and run the DisplayLink cleaner tool, found here:…

  4. Once the Cleaner has been run, reboot (even if not prompted to)

Thank you,

So what do you do after all that? I am having the same issue and have tried cleaning the machine twice and then reconnecting to docking station, loading the drivers, only to have it fail again on restart, making the computer unbootable. Once the cleaning has been done, if the drivers are still causing an issue, is it maybe something to do with the hardware? The machine in question is also an HP Envy, running Windows 8.1.

Please help.

Hi Britt,

Thanks for contacting us. In this particular instance we attempted to help the customer and communication ceased, so I don’t know what the final resolution was (if any). Again in this specific instance I believe the issue to have been a conflict between the anti-virus/anti-malware software installed on the system and the DisplayLink driver.

My recommendation at the time was to ensure the latest version was installed. At this time we are recommending version 7.7 M4 of the DisplayLink driver. If that is not the version you were installing, please try using the cleaner again and installing that version. It is on our website here –>

If that was the version you were trying or if it still doesn’t work, the next step would be to clean the system to get everything booting again and then send us an email directly at with the output of our PlugDebug utility –>

That would allow us to determine the next steps.

Thank you,
