The port replicators are VY847AA#ABA. All four the same.
The laptops are all Product Number QB648AV. Known as a dv7.
The drivers are sp46708 NIC
Sp52656 Audio
Sp52243 Video
Configurations at this time:
1. Not docked. Works fine. All drivers installed
2. Docked. Using NIC and Audio. Video driver uninstalled
3. Docked. NIC and Video driver installed. Dual monitor
4. Docked. NIC only. No other drivers
None of the laptops appear to be having issues with only the NC installed.
Any laptop with the video driver for the Display link locks up randomly during the day. This forces a hard shutdown of the system and our executives are losing work product. No a good thing.
If any laptop locks up and is removed from the port replicator the laptop will work fine for days off the dock.
I have installed all the drivers on my HP Elite 8000 and ran everything through the port replicators. No errors and no lockups. I only see failures with the dv7. I do not have a spare laptop from HP to test anther version.
I did go backward on one of the laptops to a previous driver and the results were the same. Uninstalled the old driver and all drivers are the latest on HP’s site.
I was contacted by HP engineering and we are hoping to continue troubleshooting this issue for a quick resolution. My Execs are not feeling good about me using them as test subjects.
