I tried buying one over chat, and the rep said Dell was sold out of TB15. Hopefully, they are updating the FW on the new units and waiting until problems are ironed out.
Similar problems with the Dell Thunderbolt Dock 240w with an XPS 15 9550, though it's working right now temporarily! Intermittent Ethernet connection. External displays will cycle on and off, as well as laptop monitor. I've barely tried using the USB ports on the dock, but had issues with wired Logitech trackball at one point yesterday. Per the support page I do have the most current BIOS, it is A04 (XPS 9550 A04 01.01.15 BIOS) however, not A05 as was mentioned in a previous post. I have performed the 4 firmware updates Colin linked to and all other drivers are all up to date. Spent the better part of yesterday afternoon on a chat with support without much success...Disappointing! I was looking forward to the convenience of this product, but will return it if problems aren't resolved soon. Hard to get work done when your troubleshooting this stuff!
Yes, I installed the chipset driver. The problem is that the USB controller inside the dock stops or hangs after 30-60 seconds, causing the USB ports and the ethernet adapter to drop offline.
I installed a non-Dell supplied driver for the USB controller, and that appears to have resolved a majority of the issues. However, I am still experiencing some issues with the laptop display not coming up after undocking - it seems to come up after a while, unsure of the time on that, all I know is that it locked when I stuck it in my back to come home, and when I opened it, it responded nearly immediately.
Is there an update on the fixes that need to happen on Dell's end to get the drivers working? The only solutions I am finding out there is to install ASmedia USB controller driver. I'm not interested in the workaround to change the power settings to get the docking station to work. I spend a while already installing all updated drivers for the dock and dell laptop. Ethernet dropout is the biggest issue I'm running into at the moment.
In addition to all these buggy problems anyone else agree that the ergonomics with regard to the placement of the permanent TB3 connector was not well thought out? It is on the wrong side to connect to the laptop unless this unit is meant for the Precision 7510 and 7710 but the power requirements of those laptops is much greater than the 100W max over TB3 and their connectors are on the left hand side.. It seems that the placement was decided by the engineers and that was the most convenient place to put it because of the internal components and not by someone who will be using it on a day to day basis.
This dock is a really big strike out for Dell.
Yes, the ergonomics are very poor. The biggest issue, other than the fact that at this point it really doesn't work, is the very short TB cable that is permanently installed. Yes, you apparently can take the unit apart and put on your own but really? It should have just had a TB port so that you can use whatever length of TB cable fits your installation requirement...and the port should be on the back, not the side.
Biggest problem right now though is functionality, it just doesn't work. USB and network seem to be stable for me but video (I'm using the HDMI port) cuts in and out. Also, coming out of sleep or a reboot and nothing reconnects.Yes, I have applied all updates to the drivers and bios. At this point this product is unusable.
Hey Dell, how about at least a support page for the TB15 and some clear communication to those of us that are apparently your beta testers?????
...and one more annoyance, the service tag on the bottom of the TB15 is not recognized by the Dell website so it is currently not possible to email technical support about these issue!
Have to dissent. IMHO the dock ergonomics are pretty good and well thought out.
I placed the dock right behind the laptop and the external monitors with the TB3 cable in front and connecting straight to the left of the laptop. That puts all the dock back connectors to the left (DisplayPort, Ethernet, audio, power, power brick all hidden by the external monitors) and the front USB connector to the right where I can easily reach them with my right arm. Overall, a very neat setup.
About the permanently connected TB3 cable: given the super high bandwidth of 40Gb/sec, specs call for a maximum 0.5m length (1m for the USB-C 10Gb/sec standard).
So I'm guessing Dell engineers didn't have many choices here, and decided to go for a fixed 0.5m cable to prevent people from doing silly things (like using 6ft USB 2.0 type C cables).
Sure ergonomics are not ideal, but really the main point is functionality. So let's please stay on topic here so those of us who are having issues can hopefully get them resolved.
My main problem seems to be network connection coming and going. Before leaving work last night I had 2 external monitors, USB speakers, and a wired mouse connected and they all worked fine. The network connection though! Fix it please!
