I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

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.

A:Thunderbolt TB15 Dock still not working

Return it. No amount of software/firmware updates is going to make this device good. It has several hardware issues.

If I put my computer in "Sleep" mode and turn it back on, I can never get the dock to work again. I have tried to upgrade BIOS and drivers as described in several posts, but it doesn't work. The only working solution is to restart the computer. Has anyone got the same problem?

Since the last Thunderbolt firmware update the DP ports no longer work. No matter what settings you try, no signal is detected. The only way to use monitors now seems to be to use the front USB-C port and connect it to the first monitor and then use DP daisy chain from monitor 1 to monitor 2. We have 2 Thunderbolt docks with the Update installed and both have the issue. We have one with the stock firmware and it works flawless.  Anyone else having the same issue? Any idea how to fix?

 Hello all, I am a solutions architect trying to solve an issue which I have never heard of before. Though others users are having this same issue, my experience has been different then what they have seen. First,The following are the Security options for Thunderbolt devices as per user guide

No Security: Allow Thunderbolt devices to be connected automatically.
User Authorization: Allow Thunderbolt devices to be connected after user authorization.
Secure Connect: Allow Thunderbolt devices to be connected with a saved key that has been approved by the user.
Display Port and USB: Allow only DisplayPort-compatible devices and USB devices to be connected. Thunderbolt devices are not allowed to be connectedI don't think this is entirely true or at least does not apply properly each time. My scenario:T480, T580, or Yoga x1 3rd genImaging with a standalone MDT environmentDevices come pre-configured from Lenovo with Thunderbolt 3 Security Options set to "User Authentication" Installing all the drivers in the latest SCCM driver packs that Lenovo offers - though the x1 3rd gen driver pack was missing on the site this morning. On some devices, this security option seems to do absolutely nothing. MDT uses the local "Administrator" account to perform post-OS items. I'd say about 75% of the devices reach their destination and the user logs in for the first time as a user, not an admin, and the dock functions properly; monitors/mice/keyboard/etc. work. 25% of ...

I have an HP Zbook Thunderbolt 3 dock on my HPZbook G3.  I recently updated the BIOS and firmware to the latest version to fix other "dock" issues.  Am now at the latest for both.  The dual monitors and ethernet over the Thunderbolt 3 work, but none of the USB ports are active. I'm certain the USB ports work, becuase they used to work prior to the BIOS and firmware update.  Neither keyboard, mouse, or USB memory work in the dock. I've tried going to HP support and installing any of the updates with USB in it, but it hasn't worked.  I have a workaround--just plugging in to the notebook directly, but would like to get my dock fully functional. The Device manager doesn't show any devices with issues.  I'll try to update, but I don't know which one to look at.

I purchased the Thunderbolt 3 Dock with my Yoga 920 as it was listed as an accessory during my Yoga 920 purchase back in November.  I finally got around to setting it up and I can't seem to get the power button the dock to turn on my laptop.  The button glows white when my laptop is plugged in but the button will not turn the laptop on.  I have my power button option in Windows set to "when i press power button while plugged in, the laptop will go to sleep."  So even while the laptop is connected to the dock via USB-C/thunderbolt and the laptop is on, when I push the power button the dock, it doesn't put the laptop to sleep either--it does nothing. Googling around, I see there is a newer dock called USB-C dock and it's listed as compatible with the 920 whereas as the Thunderbolt 3 Dock is not listed as compatible.  Could this be the issue?   I also have thunderbolt software installed and it detects the dock in the software. I need some help please!

I have been experiencing issues with my USB keyboard on my XPS15 9550 w/TB16 Dock when the Logitech G610 USB keyboard is plugged into TB16 USB 2.0 port in the back.
The keyboard will hang, accepting no input. or may hang on a certain letter, thus producing an "aaaaaaaa" across the screen until the keyboard "comes back".
Keyboard seems to work fine while plugged directly into the XPS15 rather than the TB16.
I also have an external USB drive for backups that I use connected to the TB16, although seems to be functioning fine. I have not had a backup fail, so, I assume it is working fine.
I have tried downloading all of the drivers, and re-installing them in the proper order according to the documentation while disconnected from the TB16, and then connecting to the dock.

Is anyone else experiencing a similar issue?  Is it the dock or the 9550?

A:USB Keyboard Hangs/Quits working on XPS15 9550 and Thunderbolt Dock TB16 . W10Pro x64

If you happen to run Citrix Receiver, make sure you're running at least version 4.9, since earlier versions are known to cause USB issues with the TB16, although that typically presents as the USB ports not working at all.  If not, then there was also an issue with intermittent USB device disconnects that was eventually solved through a combination of drivers and firmware, so when you say you've downloaded all of the drivers, please confirm that includes:
- BIOS
- Thunderbolt firmware
- Thunderbolt software
- ASMedia USB Host Controller driver

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!

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?

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).
