No power on Thunderbolt Dock

Q: No power on Thunderbolt Dock

I just picked up the TB3 dock and all seems to be working, however it is not charging my laptop using the included Thunderbolt/Power combo cable. The power light shows on the dock, and connected devices work on laptop, but no power. Any ideas?

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 a 6th Gen X1.  One of the thunderbolt ports no longer works with the monitors on the docking station - the keyboard and mouse do work.  The monitors do work when plugged into the other thunderbolt port.  I am worried that one will stop working too.   I do not know of any damage or issues and I ensured the latest drivers were installed.   Any ideas on how to troubleshoot?

(Don't know what happened to the first one I posted... Posting it again.) Hey group, While testing the performance of the SSD in my X1Y3 with CrystalDiskMark, I noticed a drastic performance drop in 4KiB Q(ueue)8T(hread)8 when connected to the Thunderbolt 3 Dock as compared to connected to AC power:  Dock: Random Read 4KiB (Q=  8,T= 8) :   318.764 MB/s [  77823.2 IOPS]Random Write 4KiB (Q=  8,T= 8) :   256.349 MB/s [  62585.2 IOPS] AC Power:Random Read 4KiB (Q= 8,T= 8) : 943.671 MB/s [ 230388.4 IOPS]Random Write 4KiB (Q= 8,T= 8) : 1024.264 MB/s [ 250064.5 IOPS] I noticed that with the Dock, the CPU usage during the test was only about 50%, whereas on AC power it was about 100%. (See the attached pictures). With the performance drop, I also heard very audible "coil whine". I can't quite tell if it was only coming from the dock or both the dock and the laptop. All connected devices were unplugged from the dock. The only two cables connected to the dock were the AC cord and the Thunderbolt 3 cable. The noise is NOT heard while using AC power. I thought the noise was just annoying before, but now with this performance drop, I'm a bit more concerned... Based on my experience with Lenovo Tech Support, I don't think I'd get any real advice from them. I was wondering if anyone else noticed the same issue and what do you think is causing it?  Thank so much for your help! ... Read more

I used System Upate to install the latest Lenovo Power Management Driver 1.67.14.05.  After this, I've noticed that my external speakers which are plugged into the Thunderbolt Dock pop whenever there is some sort of audio/video on the screen right as it loads or after leaving a web page even if no video/audio is actually playing.  This also occurs outside of just webpages, with an application that gives me audio notifications, there's a subtle pop before the sounds plays as well. I isolated the issue down to the Thunderbolt Dock only.  If I plug my speakers into the laptop directly and use the built-in Realtek HD Audio, no issue at all.  Something changed with regards to how audio is output through the dock and/or with this latest Power Management Driver update.  It's actually very annoying the popping sound that the speakers make, especially when they're turned up loud.  I tried some old solution that was Windows 10 specific with changing the minimum processor % while plugged in to 100% instead of the default of 5% in the power settings but that didn't help at all.  I'm pretty confident that this latest driver is what introduced this new issue. Anyone else experiencing this same issue, feel free to comment.

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!

Hi allWell we all now about the fan issue which is much better since the last BIOS update.Nevertheless I have sometimes fluctuation fan noise, although there is no load. This is mainly when the notebook is at the thunderbolt docking station.I found out, that as soon as I connect my notebook to the docking station more or less all app-processes suddenly move over and start running on the GPU. The CPU has virtually no load.Why do all processes start to run on GPU when the notebook is connected to the dock? Is this an issue or is there a good reason for this behaviour?My Notebook and Windos has the latest drivers/bios and updates installed.Regards,Sebastian

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).

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?

I don't see a good reason for it not to be compatiable, but wanted to find out for sure one way or the other before I bought it, as it is not cheap.

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?

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!

No Security: Allow Thunderbolt devices to be connected automatically.

Secure Connect: Allow Thunderbolt devices to be connected with a saved key that has been approved by the user.

Now, when I couple a Toshiba Thunderbolt 3 Dock with it (including 2 monitors, LAN and USB) the cpu load goes up and the laptop's fans start to run noisy. The whiole system seems to be under higher load. As soon as I disconnect the Dock the system recovers and the fans get silent again. Why is that. Can I do anything about it?

RELEVANCY SCORE 60.8

I have ethernet issues with my Thunderbolt 3 dock 150W and my Zbook 15G3, running on windows 7 / 64 bit. I had many issues before with the system after a BIOS update (slow performance, usb poorts that would't work, windows that would not download updates, ect.). I read many postst with similar problems. The hardware was exchanged by HP but the problems remained and I was left alone to install the BIOS and updates. Thank you HP!After a long period of fiddeling I got everything back to work. Exept for the ethernet connection on the thunderbolt dock. Somehow the drivers are not inatlled / available. The ethernet connection / WLAN on the laptop work fine, but not on the dock. I don't know where to find the right drivers / how to install them. Who can help? 

A:Ethernet on thunderbolt dock won't work

I have the Zbook 15 G3 Mobile Workstation using the Zbook Thunderbolt 3 dock: http://www8.hp.com/us/en/workstations/zbook-dock.html I am sending this on the Zbook connected to the dock using its gigabit ethernet port. HP Support Assistant provided all the drivers needed for the dock. Here is the screenshot of my device manager:    What does your device manager look like under network devices? The Intel ethernet is the built in and the Broadcom NetXtreme is the ethernet in the dock. HP has drivers for both on the support page for Windows 10 64 bit under the Zbook G3 Home page.  I did have a bit of a struggle initially getting the dock to work but I went into the BIOS and disabled all Thunderbolt security settings. If you need any more help post back. If this is "the Answer" please click "Accept as Solution" to help others find it.
