Hi,

I'm not sure what USB 3.0 host controller drivers you have tried but can you try the latest (v1.0.8.251)?

Thanks,
James

I tried this version and also some others. None solved the issue. In meanwhile I sent it back for replacement. Could it be that it is related to Nvidia GT650M drivers?

Id like to know your secret to getting a replacement under warranty.

I contacted Lenovo and the customer service was horrible. I opened a ticket and they closed it without telling me and when I called back a week later when I didn't hear anything they said they wouldn't warranty it because it was because i didn't install the drivers? What??? i tried every driver there is.

They told me i would have to format my work pc and reinstall the drivers on windows 7 (CHANGE MY OS??!?!) and then if it didn't work they would send me a replacement and then i would have to reformat my computer again and reinstall everything.

Yeah right... like I'm going to do that. Idiots.

Plugged my dock into my machine today to try the 7.3 drivers and all it does is make my laptop screen flicker on an off repeatedly about 2-3 times per second and the external monitor doesn't come on.

Can't try the new drivers and I'm positive now the dock is bad.

@dhodgin: I sent it back to my reseller. Lenovo will not provide me support as long as I do not try it on a Lenovo notebook (got this information on phone from Lenovo).

I finally got a replacement and the replacement unit does the exact same thing.

I took the dock home and hooked it up to my home PC desktop and it works no problem so far with the 7.2 M1 drivers on windows 8 with 3 monitors (2 on PC, 1 on dock)

I was able to get the firmware updated on the dock via my PC and then uninstalled everything on my laptop, and ran the clean utility, then reinstalled the latest lenovo drivers with 7.2M1 then installed 7.3M1 and reconnected the dock to my laptop
same problem, laptop screen flashes repeatedly and the external monitor doesn't come on at all.

with just usb and Ethernet plugged into the dock it seems to be stable, as soon as i connect the external monitor DVI cable it flashes the laptop screen repeatedly and doesn't show anything on the external monitor.

it's just connecting and disconnecting the external monitor repeatedly over and over on the laptop. Stable on desktop PC

I also got my dock back.

Lenovo did a 24hr test and did not face the problem :-(

When I connected the dock it was updating the firmware and except of 1 disconnection during 10 hours I did not face the problem anymore.

While it was at Lenovo I installed a different version of the Intel USB3 drivers for solving another another problem.

Later I installed DisplayLink version 7.3 and this also runs fine so far. (driver in device manager seems to be still 7.2)

So my conclusion so far:

• Lenovo did something special with the dock
• there is only 1 working version out of 5 USB3 drivers
• maybe related to any Nvidia driver
• operating temperature (before sending back I used it in ~30°C)
