Thunderbolt 3 Docking with Yoga 370 runs hot

Q: Thunderbolt 3 Docking with Yoga 370 runs hot

Since Firmware 4.04 the Thunderbolt Docking runs hot.It smells like slow "burning" plastic. My whole office smells like "burning plastic" after 2-3 hours in use.I have checked all items and found that the plastic smell comes from Thunderbolt Docking.After Update to Firmware 4.4 nothing changed. It smells and I'm afraid that it burns some day. I have changed the Docking to another new one. Flashing firmware to 4.4 and same issue. The new one also smells after 2-3 hours like burning plastic. That's not normal ... My configuration is:- Yoga 370 connected with USB-C (only USB-C connected for Data and Power)- two EIZO Monitors connected on Thunderbolt-3 Anyone have this same problem?

Hello Everyone, This is my first post in the community, which is also why i might not be in the right section. Apologies in advance! I work in IT, and i help manage different Lenovo Thinkpads. We current have 20-30 Yoga 370 in our network.  On more than one occasion i've experienced this model running extremely slow. So what i did was, i pulled up the task mgr, but nothing seemed out of the ordinary. CPU was running steady at 40%ish, and plenty of RAM available. Reboot didn't resolve anything. The only thing which fixes the issue is unplugging the Docking Cord (USB-C), and plugging it again.  I was wondering if this is a known issue. Because i've experienced it around 10 times, but never frequently on the same machine. It's not the biggest problem, but i would like to know if anyone else has experienced this.  Best regards Jeppe

I am struggling with my docking station for my ThinkPad 480s.  I have two docking stations.  One by Lenovo type 40AJ and the other by DELL.  The dual monitor DP setup resets every 3 to 5 minutes causing the monitors to go black with the Lenovo UltraDocking Station.  So I switched out that docking station with the DELL universal docking station.  When I use the USB C/Thunderbolt port the same thing happens.  When I use the USB 3 port, I have no problems.  I have looked in the event viewer and I can see where the laptop switches from external to battery power, but nothing else.  Also, I have updated the drivers for Thunderbolt. Has anyone seen and resolved this issue?

I am using this Zbook 17 g3 for the third week now. It is significantly fasters than the elitebook 8760W it retires. There is still some issues not resolved. I have established a routine to making docking to the thunderbolt 3 work. I have one thunderbolt 3 at home and another in the office.  I found to have the thunderbolt 3 docking work properly I need to log in to the laptop standing alone without having it connected to any device. The external keyboard and the mouse are both connected to the thunderbolt 3 via USB so when I start up they are both inactive. After the laptop starts up, I then plug in the thunderbolt 3 to the laptop to provide it with power and communication. The screen (dual monitor in both locations) flashes and then the second monitor, external keyboard and the mouse work this way. If I plug in the thunderbolt 3 connector to the laptop right when I start up, it will not communicate with the laptop which means the external keyboard, the mouse or the second monitor all will not work.  I think this is not right. I'd like to be able to walk into the office, or home office. Dock the laptop. Turn it on and every device works, like any HP docking device I used to have. But before I found an alternative my established start-up procedure is an acceptable work around. Not good enough. But I'd live with it. How is everyone else's experience with the zbook 17 g3 docking to the thunderbolt 3? Another issue is I have not yet had the USB ports on ... Read more

I recently received a ZBook 15 G3 with the ZBook dock. After installing Ubuntu 16.04 the dock didn't work at all, it only powered the laptop. I changed the BIOS security configuration for the Thunderbolt port (under Advanced, Ports) and was able to get an external disply working.However, the USB ports on the dock are still not working, the audio jack isn't working and the ethernet port isn't working. When connecting a cable to the ethernet port on the dock the laptop will show that it's connected but there still isn't any internet connection.I will appreciate any help as right now the dock is pretty much unusable.

I have a 5th gen Carbon connected to the Lenovo Thunderbolt docking station. After some time, perhaps a sleep or hibernation, the laptop loses ethernet connectivity and can only use wifi. ipconfig reports media disconnected. But if I do a restart of Windows 10, ethernet is back, no problems. Also if I use the ethernet dongle connected to the laptop's weird little ethernet port, there are no issues.  There are other issues with the dock, like intermittent loss of wireless keyboard and mouse connectivity, but I'll worry about those in another thread.

Hello Everyone, Lenovo?s Workstation customers are very active in the forum community and we would like to reach out to you for feedback on an upcoming Thunderbolt Mobile Workstation Docking solution. We value our customer?s feedback and would love to hear from you!As you can imagine, Thunderbolt docking stations require quite a bit of power and Lenovo is considering two power delivery options. Option A) Would be a single and very large power supply/brick.  This would supply power to both the Thunderbolt dock and the mobile workstation system.  The potential downside would be the large physical size of this power supply and higher cost/price. Option B) Is a dual power supply/brick design that would leverage your existing workstation power supply and a standard ThinkPad power supply (both connected to the dock itself).  Advantages are lower cost/price and smaller power bricks, but could be troublesome for users that travel with their system who would have to disconnect and carry the system brick (or purchase an additional one)  Which would you prefer and why?  Thank you in advance for your feedback!

Hopefully someone here can help me before I get an aneurysm. I got the HP Thunderbolt 3 Docking Station (150 watts, model number P5Q54AA). Everything is connected ok but as soon as the dock connects to my laptop it crashes my computer instantly and generates the blue screen of death. It doesn't matter if a monitor is connected or not. There was a couple of scary moments when it sent my fans into overdrive and started beeping loudly as if a bomb was ready to explode. I spent more than eight hours on this yesterday and at this point the dock seems like nothing more than a nice looking brick. I have went through all of the help threads here and tried everything. I updated the bios from 1.14 to 1.15I updated all audio drivers, graphic drivers, firmware drivers, chipset drivers, and thunderbolt related driversI rolled back everything twice and reinstalled everythingI removed the security setting in the bios that relates to thunderbolt devices connectingI've made numerous other changes that didn't work and had to roll backNothing seems to work. I am puzzled as to why HP haven't set this up better. Surely there needs to be a dedicated app for this that handles everything and installs and removes all necessary drivers. By the looks of it this docking station has been a mess from the start. What else can I do at this point?

It is possible you have a defective dock. I have exactly the same setup and went through some difficulties when I first got it but turning off Thunderbolt security made mine work. It is still occasionally finicky coming out of sleep mode or if I disconnect the laptop and use it as a laptop then try to reconnect the dock. Takes a restart or 2 sometimes but mine generally works well.  I would suggest your problems point to a bad piece of hardware.

I have several Dell 5510 Precision series with the Thunderbolt USB-C adaptor. Each 5510 is plugged into a Dell K17A docking station powered by a Dell 130W power supply. When I connect the docking station via its USB-C connection to the 5510 laptop, I get a BIOS warning that it only sees 95W of the 130W. But the battery charges and the laptop runs. I can turn off the power warning in the BIOS (which is current) but I worry about powering the 5510's Nvidia video card and other components if the BIOS is not seeing all 130 watts.

I have just bought a Dell XPS 15 (9560) and a Dell WD15 docking station with 130W power brick (same wattage as the laptop's AC-adapter). When I only use the docking station to power the laptop the discrete graphics card (GTX 1050) does not seem to work. When I am in a game (eg. Starcraft 2), I get like 15 fps with the NVIDIA recommended settings. Then when I plug in the laptops's own power brick (while still in the game) I get an immediate four-fold increase in framerate. When I unplug the laptop's own power brick the framerate drops down to 15 fps again in a heartbeat. Furthermore, when I only power the laptop through the docking station, I cannot even find the discrete GPU in the list when I'm trying to run the Geekbench 4 compute benchmark (OpenCL). Only the integrated graphics shows up. When I plug in laptop's power brick I find GTX 1050 in the list.
I have run the Dell Command Update application and all my drivers and firmware are up to date.

If I take the laptop out of the docking station or do not have the power cord plugged in, the laptop runs great. Please help me.

Can you precisely identify the process hogging that CPU?

You could download and run the free Process Explorer. You'll be able to precisely identify the culprit. By right-clicking on the process showing high CPU and selecting Properties… > Threads tab, you'll be able to pinpoint the thread that's hogging CPU within the process. You'll need to slide the bar left of CSwitch Delta in order to see the CPU values.

Process Explorer doesn't require any installation. Simply run the executable file once downloaded. Then, configure the Process Explorer window to your liking. You can even replace the Task Manager (CTRL+ALT+DEL) by clicking on Options > Replace Task Manager. You'll get a lot more features and details than with the Task Manager.

To determine which Process might be hogging CPU, click on the little graphs located at the top right of the window. A new window with four graphs will open, the first one being CPU. Click inside the window and press the spacebar to freeze the display. This will make it easier to hover your mouse cursor over the CPU peaks in order to read which process(es) is/are creating them.

A:Thinkpad Thunderbolt 3 docking station does not charge Thinkpad P51 battery.

Everbody's p51 would be the same.  The thunderbolt port won't work as a charging port.  The thunderbolt specs specify 100w max.  That's not enough.  Your thunderbolt port is not for charging.  To charge via the dock, you need a workstation dock, not a thunderbolt dock.  A thinderbolt dock can charge things like an x1 carbon (5th gen) or x1 yoga (2nd gen)

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?

Authorizing the device again doesn't do anything. The display stays dark and any USB device plugged into it doesn't show up and doesn't even appear to be powered on.

I'm using the thunderbolt port for a single connection to a Dell usb-c dock (power in, KVM out, speakers, network, etc.).  The 720 charges real slow and the battery status message (in Lenovo Settings app) states that the "AC adapter cannot provide enough power for normal operation of your computer".  The Dell usb-c docks are powered with a 180w power supply that provides 60w of power to the computer, which is more than the 45w power supply that comes with the 720.  I have tried 3 different Dell docks, including a Dell thunderbolt 3 dock with a 240w power supply. I have to believe this is an issue with the Thunderbolt 3 driver on the 720 or something BIOS related.  BTW, the 720 has Windows 10 pro loaded (updated from the home version loaded by default) and Bitlocker enabled.  Don't think these changes have anything to do with the issue. I purchased Lenovo's thinkpad usb-c dock (which states that it's universal) and hope it charges the 720.

Pardon me if this is a repeat question, I couldn't find a solution before posting.  I'm not able to see how to enable the USB-C / Thunderbolt port on my Yoga 370 to charge my phone.  Nothing happens when I plug in, although I get I beep out of device manager that something's connected.  I am able to connect the same cable / phone to a Lenovo Thinkpad USB-Dock and the ohone picks right up and starts charging.  Is there sometning I con configure to enable this behavior on my notebook?

Hi! Ive just bought 2 new Full HD monitors to feed them using a Thunderbolt 3 Dock. My problem: one of the monitors has a colour issue showing purple instead of green. Sometimes the right one, after restart the left one a.s.o. - I changed cables from DP to HDMI and VGA: ever the same- Ive tried the second thunderbolt port of the docking station Once even the laptops display itself showed the wrong colours but it now works fine again.Im not able to get the tweo external monitors working together with the right colours. Neither including the Yogas display nor when Yogas display is turned off. What to do...? Best regards!

A:Yoga 370 & Thunderbolt 3 Dock monitor issue

Solution: Settings were changed in the Intel graphics settings AUTOMATICALLY for one display - one colour value has been set to a wrong value. As Im the only one working with this machine its kind of weird - Ive nevr been to the additional intel graphic settings before.

hi, I have setup one of my faculty with a Yoga 920131KB plus Thunderbolt 3 Dock. He has an existing monitor (Samsung Syncmaster P2450) that should support 1920x1080. Seems to be current on all drivers and patches under Win10 EDU version. (Including the CCG4 Firmware Update to v55). We are using the HDMI output from the dock. If we try to configure extended desktop to the Samsung monitor at 1920x1080, the screen extends off both sides about half an inch. Maybe also a quarter inch over at the top.  As a work-around, set at 1680x1050, video generally works as expected, but the display starts about 2" in from either side. Generally I don't like using add-on utilities (prefer to just use standard windows built-in options), but somewhere along the line this has the Intel Graphics HD Utility.  I was using that to switch resolution, the Windows settings seemed to track along with changes in the Intel utility, but still overscanned the display.  I played with some other settings in the utility about Display Scale (other than 100%), didn't seem to change anything. A second problem occurs with this setup: when the laptop is used at home, put to sleep, then plugged into the dock, the screen is displayed on the external monitor at maybe 200% (?).  That is, you only see the central portion of the image.  No fiddling with settings seems to correct it, but rebooting usually fixes it. The second problem also occurs with a similar Yoga 920 + Dock (d...

Also wanted to mention something I noticed while working on this: I saved a log from the Intel Utility. There is a section in there about "Maximum Image Size". This seemed to be correct for the laptop display (12.2"x6.69") but the Samsung was listed at 6.3" x 3.54"    It is a 24" diagonal display, so that is obviously wrong, but I don't know that it is important. Intel(R) UHD Graphics 620 Report Date: Monday, February 5, 2018Report Time [hh:mm:ss]: 1:21:19 PMDriver Version: 23.20.16.4849Operating System: Windows* 10 Education (10.0.16299)Physical Memory: 16225 MBVendor ID: 8086Device ID: 5917Device Revision: 07Graphics Output Protocol (GOP) Version: 9.0.1066Current Resolution: 1680 x 1050 Display Type: DigitalDDC2 Protocol: SupportedGamma: 2.2Connector Type: DisplayPortDevice Type: DisplayPortMaximum Image SizeHorizontal Size: 6.3 inchesVertical Size: 3.54 inches
