Apart from as previously mentioned attaching the logs I'd recommend you:

Attach a list of all running processes on your computer (run this from a command prompt wmic process get description,executablepath).

What is your current power plan (listed under Control Panel\Hardware and Sound\Power Options)?

List what exactly is attached to your dock when the system freezes.

Try resetting the BIOS to it's default settings and see if it still happens.

That is interesting, and makes it even more important as to what hardware users are using. As far as I am aware, and no-one has stated differently, this is all occurring with the HP Media Docking station.

If the DisplayLink software is not installed (ie no DisplayLink Core Software in Control panel-> programs) and the PC is still freezing, then it becomes less likely to be DisplayLink software issue. There are also audio and Ethernet drivers for the devices on this dock, but they are not provided by DisplayLink. We only provide the video output on this dock.

Could you also try disabling the Ethernet and audio to try and work out what component is causing the freezing?

Thanks

Wim

My computer froze twice today, with the DisplayLink core software NOT installed and the dock disabled.

I have now reinstalled the DisplayLink Core Software and enabled the dock, but DISABLED the audio driver (HP Media Port Rep Audio). I'll report back in a few days.

Stan Kynerd

Used configuaration above all afternoon and no freeze; couldnt stand waiting, so I uninstalled the current driver HP uses for the dock (Conexant version 1.29.8.0/HP USB Media Port Rep Audo), and installed the previous USB audio driver (1.25.00A); will report back when something becomes evident (either a freeze or no freeze after several days).

Stan Kynerd

Thanks skynerd. Please let us know if there is any update. It would have been good to find the cause of the issue.

Could other users with the issue try the same change with the audio drivers and see if it solves the issue?

Thanks

Wim

As noted I rolled my USB audio driver back to 1.25.00A; I am happy to report that since I rolled my audio driver back, my computer has NOT frozen (I DO have Display Link Driver 5.6.31854.0 installed and enabled).

At least for my system, the problem appears to have been the audio driver and not the Display Link Driver.

Wim: thanks for staying with us on this issue.

"Freezing" HP Displaylink Dock issue.
 

Hi.
We have also had the "Freezing" HP Displaylink Dock issue.
We have HP 5330M i5 Processor. This is the HP model running Beats Audio.
The dock we are using is the HP AY052ET#AC3
This doesn't have audio. We have the dock set-up to passthrough Ethernet, Display, Mouse and Keyboard (in other words, the standard set-up)
We have found that switching off Aero Transparency seems to make a difference to the freezing in IE.
Please can display link advise on what the situation is regarding the stability of this product and the best (most stable drivers) we should be using.
thanks.
Andy

Do you actually have the same problem on this thread of the whole laptop freezing, or just the screen attached to the dock?

This thread is about the whole system freezing. If it is different to this problem, please raise a new thread, with details about your system, having tried v5.6 M1 and v6.0 software to see if they solve the issue.

In the same boat without a paddle
 

Laptops (3) are HP dv7

USB Media Docking Stations with the latest drivers from HP

Laptops freeze several times a day. Disconnect the docking station and the laptops work fine.

Has there been any resolution to this issue? I am getting ready to ship all three docks back to HP without a clear resolution.

Have you tried rolling back the audio drivers as stated in post 46? The audio drivers are not provided by DisplayLink, so this should be raised with HP directly.

Thanks

Wim

Two of the Port Replicators VY847AA#ABA
are attached to the audio base. They have been rolled back with no good results.

The third one has no audio nor has the driver been installed. Still freezing.

I have two tech case numbers in HP and the case manger has now said he has finally received two more cases. They are only offering refunds no fixes.

I attempted to duplicate with one of the replicators and all the drivers installed on my HP 8000 Elite. Nuts, worked fine. Seems to be only the laptops.

Follow up
 

Anyone had any update on this situation? It is pointing at the Display Link software and I would like to hear that They and working with HP.

We have contacted HP about the audio driver, as this is not provided by DisplayLink.

I'm assuming that if you uninstall the DisplayLink software and connect the dock, the freezing no longer occurs? Is that correct?

If this is the case, could you post the logs from one of your freezing systems to see if we can see anything unusual? Also, could you try v6.0 M1 which has just been released on the DisplayLink website.

Thanks

Wim

More testing
 

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. :)

Hi Rick

I understand your execs not wanting to be test subjects. We have that problem here :-)

Just to be clear, with configuration 2 (Docked. Using NIC and Audio. Video driver uninstalled) the laptop did NOT lock up?

Have you tried v6.0 M1 from the DisplayLink website to see if this makes a difference? Are there any particular applications they are using at the time that cause this?

Thanks

Wim

Updates?
 

Has there been any updates on this?

The problem was brought to this forum 5 months ago, and as far as I can tell, there is no resolution, and HP is still selling non-working product.

Any news here?

There has been a resolution from one user finding it was down to the latest audio drivers from HP for the dock (not a component provided by DisplayLink). See post 46.

We have tried to reproduce this, but cannot - even on the same PC systems quoted here. We are reasonably sure that this is not directly related to DisplayLink software, but other components and drivers needed for the dock provided by HP. I think HP support are in the best position to try and reproduce this and find the offending driver component.

Thanks

Wim

Whole system doesn't freeze with HP Pavilion
 

We are experiencing the freeze however all we have to do is unplug and reconnect the hub power supply and the system is back where it was. The actual laptop is not freezing. Please advise if there's a fix for this. It looks like this has been a reported problem for quite some time.

Yes, this is a completely different problem that should be solved in v5.6 software or later. Please open a new thread if you have freezing with v6.0 M1

Thanks

Wim

still freezing
 

Wim,

The laptops (2) with the version 6 from Display Link are still exhibiting the same issues. As you can see from my posts I have almost every configuration with aduio, video and NIC. The problems persist.

Worse yet, I have one laptop and setup that is IDENTICAL to all the others with NO errors. Go figure. It is running all the original drivers with no updates.

I think this is a HP problem but still waiting for them to fix the docks.

Question to all - did anyone setup the laptops with an image or do you experience the issue with the OEM installed systems as well?

I see this problem is not followed up yet. I have the same problems using an 5320 i5 HP laptop and the docking S02X. Sometimes my notebook freezes. I can solve it very quicly by closing the lid of the notebook and open it back again. The notebook unfreezes and I can continue working ... not very good but on the other hand I have not a very big problem with it. However I have a HUGE problem with the blurring screen attached to the docking. It is really not amusing and very disturbing. I sometimes even have some medical issues because of it ...
Is it too much to ask to get a correct working device if you buy something?

grtz,
Peter

I have the exact same problem as boskensp.
This happens on almost 1/3 of all 46 USB docks we currently own.

As we only use our external display at the office, the laptop lid is usually closed, and when the screen freezes, it can be fixed by open and closing the laptop lid.
All out laptops are HP, but 6 different models. Most of them with Intel HD3000 display adaptor, but also some with ATI or NVidia graphics cards.

Almost every laptop have a Intel processor, but two of them have AMD processor, and they freezes more often than others.

Sincerely
Christian

This happens for me on both.
