I just installed the latest set of drivers. The dock still does not connect to my XPS 15- 9550.
This process has gone on for two months.

Hi 
I Just bought TB15 and stated using it.
The problem, however, is that my XPS 13 becomes pretty hot when it is connected to the dock.
It becomes hot and operates fan even for normal light uses like web surfing or listening music.
Is it normal issue that all the user have or abnormal?
Thanks!

Additionally, when i connect intel realsense camera to TB15, all devices connected to TB15 is disabled and does not work. The laptop must be restarted to be operated normally.

Hi,
I recently set up my XPS15 with a TB15. Everything is working well so far, however, when I plug headphones into the front-facing audio jack I still hear the audio through my desktop speakers (plugged into the back of the TB15) and not my headphones.
Ideally, I would like to be able to keep the headphones plugged in and simply switch back and forth before outputs with some Windows 10 option. Is that possible? If not, how to I get just the headphones to get audio?
Thanks!

Good afternoon,

I have just recently purchased a Thunderbolt TB15 from Dell. I was so excited until I connected to my laptop.
I followed the instructions for the drivers installation http://en.community.dell.com/support-forums/laptop/f/3518/t/19677047
It didn't work. I remove all the softwares and tried again, still no improvement.
I finally gave Dell support a call, but it didn't resolve my issue.
So, I am currently able to get a power from the TB15, but that's it. All other ports, USBs, Ethernet, etc. are still not working.
When I plugged an Ethernet cable, I can see the blinking on the TB15 but it didn't connect to my laptop.
I have a 9350 series.
FYI, I searched on this forum and tried to do all the suggested solution, but I have no luck.

Please let me know if anyone of you has a solution for this.

Thank you

Dell XPS15 + TD15 is the biggest fail of 2015 and 2016.
This is unbelievable example of software team incompetency.
If XPS15 works in common stable after 6+ months after sales started.
While TB15 not only lags, but every new software update adds new lags and bugs, even not always fixing previous. This is unbelievable worst software processes.
And this is one of the best PC laptop and one of the best Thunderbolt dock.

The problem is not new:
I have Dell XPS15 9550 + TB15.
Sure this doesn't work with a closed lid with any configuration.
But it doesn't work even with opened lid. I used this manual to configure and update drivers/firmware.
It was working for me in June, and first part of August (sure with lags, but I was able to work with this).
But then, suddenly %), without any updates, lags frequency increased. And my external monitor became turning off every 1-10 minutes. Sound and mouse too.
Without any updates, like a magic.
After updating from scratch of all drivers and firmware (the same manual), nothing changed.
Actually I think monitor works with more lags.
As a customer who used V131 laptop, Dell monitor for many years, it looks like that were last products I purchased..

Just received my 4th XPS 9550, previous onces had faulty motherboard, keys falling off, and faulty hard drive). I updated everything straight off of the dell website, including the bios. But I still can't get my thunderbolt dock to work. I plug it in and makes the noise indicating something is being plugged and unplugged. It looks like it can't decide between being on wifi or LAN and the Realtek USB GbE family controller keeps on disappearing in the device manager. I have updated that drivers as well.
XPS 15 9550 i7 500GB SSD 16GB RAM Windows 10 64 Pro
The dock will somewhat work if I don't have the LAN cable plugged in the back. I can't use any wireless devices (mouse) plugged into the dock because it stops working after a minute. I've also noticed the ASMedia USB controller has fault icon on it. Tried updating those drivers. Every once in a while, the second monitor will go in and out.
I have conducted all their diagnostic tests and all are good.
Anyone have any suggestions?
I'm a student and need my laptop everyday. If this is another hardware issue, I'm going to return it. I doubt the 5th unit in 1.5 months will be any different.

A:XPS 9550 not working with TB15 Dock

If it's of any consolation, we are all experiencing the same problems:
1) LAN disconnecting2) USB devices connected to the dock disconnecting3) External monitors blanking out for a few seconds4) Fans ramping up and extremely noisy when dock is connected.
It's not the laptop (I replaced 3 for the same reasons you mentioned). It's most likely (or at least I hope so) the thunderbolt software/firmware.
I'm still trying to decide whether to return my TB15 or wait for Intel/Dell to fix this...

I have a new XPS 15 9550 and a TB15 dock.  Thus far, the road has been long and hard to get this PC operational.  One of my couple remaining issues is that when I plug an ethernet cable into the TB15 dock, it appears to crash the dock.  I lose video and audio output from it.  To recover, I can unplug the ethernet cable, unplug the Thunderbolt cable from the PC, wait a few seconds, and then plug the Thunderbolt cable back in.  I have installed all of the newest network and dock drivers for the XPS 15 9550.
Is anyone else having a similar problem?  Any ideas on what I could do to resolve it?
Thanks!

Hello,Everyone appears to have issues with the dock such as a port not working or stuttering or resetting. But I am not having ANY of these issues. The only issue I am having is I cannot close the lid with an external monitor. I have already changed the settings on the XPS 9550 to "Do Nothing" when the lid is closed both on battery power and without. I also plugged it into the power adapter just in case.
What happens when I do close the lid is the external monitor goes to sleep and ALL peripherals connected no longer work (including display) after opening the XPS again. I have to restart the computer for the dock to work again.
No overheating issues, no fan issues, no stuttering, other than this small problem. Anybody have any solutions? 

A:XPS 9550 TB15 dock combo, closed lid issue?

This isn't a TB15 issue. I've seen the same problem with third-party USB-C video adapters. I believe it is a power management problem. If you're using Windows make sure your power management features are configured so that when the laptop lid is closed Windows will "Do Nothing" when you're connected to AC power. (YOU DID THAT.) If you're using a Dell monitor, I found that some of them have hyper- aggressive power management features. On my UP3216q, there's a setting to disable the monitor sleep feature but it doesn't work. And there is almost no delay between when the monitor loses the picture signal and it begins its sleep countdown. If I reboot my XPS 15 9550, the monitor will be asleep before the machine comes back up. I'm using Windows 10 and I also have some questions about the power management features there. In fact the whole settings/control panel dichotomy is really screwed up.
I have an additional problem with closing lid — it can cause the monitor to blink on and off. This seems to be a Dell laptop to Dell monitor problem. And it may be 4K and/or USB-C related. Here's how I solved the problem, and you're not going to like it. But I'm getting used to it: I just tuck the laptop under the monitor edge and leave it open 3 inches.
By the way, I'm not having any problems with the TB15 either. In fact I just ordered a second one. You really have to keep up to date on the drivers and firmware, though. The ones... Read more

We recently started using Bitlocker with a PIN at startup. On all our laptops using the "old"-type dock, that you click your laptop into everything is working fine, the users put the laptops into the dock, turn it on, type in the Bitlocker PIN using the external monitor and keyboard, and then processed into Windows. Our problem is with everyone using the new Lenovo ThinkPad Thunderbolt 3 Dock. When the users connect the laptops to the dock using the cable and then power on from the dock, the laptop will power on (the LED in the ThinkPad logo lights up) but the monitors and keyboard connected to the dock is not working, and then after some time the laptop will power off again. We currently use a workaround where the users power on, type in the Bitlocker PIN and login to Windows before connecting the laptop to the dock, but this not a proper solution. We have Enabled both "Thunderbolt(TM) device" and "USB device" under "Support in Pre Boot Environment" in the "Thunderbolt 3"-menu in BIOS, but it still doesn't work. Have anyone else experienced this problem?

Hi,I have a Thinkpad P50 and today my Dell Thunderbolt Dock arrived.Unfortunately, it doesn't work  (= it is not recognized in any way), although Dell specifically says that the dock also works with non-Dell Thunderbolt 3 machines. I have installed the Thunderbolt software from the P50's driver site and updated to BIOS 1.17.Lenovo released an "Intel Alpine Ridge Thunderbolt Firmware" for the P70. But there's no such firmware update on the P50's site, just the Intel Thunderbolt Software from November.The 1.17 UEFI/BIOS Update says it fixed a Thunderbolt issue, but apparently not mine Has anyone ever gotten some Thunderbolt 3 device working on the P50? I just hope this will be fixed soon, because the Thunderbolt dock seems to be the only convenient way to drive three 4K displays with the P50 (2 via Thunderbolt 3, 1 via miniDP).

Hello all,I bought a Yoga X1 2018 and during the shop they suggest the Lenovo Thunderbolt 3 Dock. Since I thought that having to disconnect only one cable when bringin the laptop from the desk to the meeting room would have been useful, I bought it.With my disappointment I setup everything and I did some tests on the laptop just to discover that the performance of the laptop when powered through the docking station are 1/3 with respect to when it's powered by the 65W power supply and 1/2 of when the laptop is on battery... (234pt vs 640pt vs 563pt | dock/65W/battery)Now since the docking station has a 135W power supply, I really can't think that this is an issue with the supply from the docking. Also since the laptop is even faster on battery I really don't understand how it could be related to the power supply... anyway I've connected both the 65W power supply and the docking and the performance are back to normal.Is there anyone who can suggest me what's going on or how to report this to Lenovo?

Love the concept of the thunderbolt 3 dock, can't fathom how it was designed though.  On my zBook 15 G3, the power and thunderbolt ports are on the right side of the laptop.  The dock has the cable port on the left rear side, completely crossing over all the ports when you put the dock on a desk with the back facing away from  you.  Then they ship a cable that is barely long enough to put the dock directly behind the laptop and connect it.   Where do I buy a longer cable HP, please!

As the only docking solution available and moving from a more traditional dock, its less than suitable.  HP needs to make a longer cable and the end that connects to the laptop should be at a right angle.  The cable is so stiff and thick it takes nearly 4" to make the turn.  HP makes it impossible to find this out how long the cable is with out purchasing and at that point your stuck with it.  Hardly a customer satisfaction issue they should want to propigate!
