Unplugging USB dock causes reboot Windows 7

[ebmaynard]

I looked before posting but didn't see this issue, so hopefully not re-covering something you guys have already discussed.

Dell Vostro 3350 running Windows 7 Pro 64 bit reboots whenever I unplug the USB cable to the dock. Using a Targus ACP51USZ dock and recently downloaded latest DisplayLink drivers from their website.

When I remove the USB plug, the display on the laptop flickers and thinks about it for a moment, then the unit reboots. No blue screen, no errors, it just goes black and then you see the Dell logo as it starts. This happens without fail, every time.

I have the latest Dell driver for the video and updated the BIOS to try to see it they helped but no luck. I also ran the DisplayLink Support tool and will include the zip.

Any help is much appreciated. Thanks!
