thunderbolt dock 3 won't charge t580

Q: thunderbolt dock 3 won't charge t580

My thunderbolt 3 (135watt) dock will not charge my T580 intel core i7-8650 laptop while displaying on 2 monitors. Tried only 1 monitor and still won't charge. About 3 months ago first got a message that insufficient power to thunderbolt dock. Warranty replaced the dock last week and still won't work. I took the laptop to work since I have an identical rig and it charges and displays (only 1 monitor but will also charge an iphone). I brought a new 135w charger home and that didnt help. Also replaced little cord from thunderbolt to T580 and that didn't work. I even tried a different outlet on a different circuit and that doesn't help. Could it be that the i7-8650 needs the 230W thunderbolt?

Hey, I have a HP Elite 90W Thunderbolt 3 Dock that works fine with the hp work laptop that I have and 3 monitors. I just bought a simple thunderbolt 3 cable to be able to plug my Lenovo T580 to this and enjoy the external monitors with it as well but... it doesn't seem to work. (I don't know if it's relevant, but my t580 runs linux) I did try to look around on the internet but couldn't seem to find anyone who tried to do this. So is it normal ? Or is it supposed to work ? If so, could the problem come from linux ? Thanks in advance if you have any idea !  Cheers

(For those of you who have followed my previous threads, I've now ordered a T580 with 4k display). I'm looking for a T3 dock which can do the following on a T580. It would allow me to use just one cable to dock/undock it: 1) Attach a screen with a 2560x1440 resolution with 60Hz (digital connection)2) Attach a screen with a 1920x1200 resolution with 60Hz (digital or VGA connection)3) Full Ethernet port4) Charge the laptop (originally, it comes with a 45W power adaptor)5) Have at least 1 classic USB 3.0 port Unfortunately my budget is limited so that I can't go for the original Lenovo one. If there's a dock which can all the above except for attaching two screens, then this would be ok as well, for the time being (assuming I can run one screen via the dock, and the other screen directly from the HDMI of the T580). Then it would just be 2 cables for docking/undocking...

Hi all, In the past few days my laptop slowly degraded, starting with docking station connectivity not working (but does work with other laptops), then HDMI port not working (HDMI screen and cable works with other laptops), and now system no longer charges. Current status is that all USB-C ports (including charge) and HDMI port and not functioning. Computer doesn't charge when it is off, too.  I've looked at multiple solutions and threads on this website without any real solution. I've already tried - - run Lenovo Vantage a few times to check updates. Did the same on the Lenovo product website (using auto-discovery of serial #), everything is fully updated- Turned on/off Thunderbolt Service (on the Windows 10 control panel) - I turned it on and automatic but it always returns to Manual- Searched in the Device Manager for Thunderbolt (anything) - it's not there- Uninstalled and re-installed Thunderbolt software from the Lenovo website (both controller driver and FW, file names n1nta05w.exe and n1nth08w.exe)- Went to the BIOS/Configuration - enabled and disabled again all Thunderbolt related options - Used Paperclip to do hard reset using the emergency reset button Any ideas what left to be done?  Thanks!

I used the Lenovo System Update (v5.07.0074) and was prompted to download and install (was listed as Critical Update) the Firmware to my Dock.  As always, I closed all applications and sat as the Firmware downloaded. I got the expected prompt to ensure I was plugged in. I then watched as the upgraded prompted me to install. Installation completed and everything appeared to be fine.  I powered down the thinkpad and disconnected. Worked from the living room, then went back to the dock. Connected, and noticed that before I connected the White light on the power button was illuminated. Shrugged, and pushed the power button. Nothing. I un-plugged the Dock, got a cup of coffee, returned and plugged it back in. Nothing. I then noticed that none of the pass-through power was working on the dock.  So, I unplugged it again.  Unplugged everything connected to it, and held the power button down for 15 seconds in an effort. All of this at the recommendation of Lenovo Support. Who, by the way, was very nice and well spoken. Nothing we did worked. I happened to have another Thunderbolt 3 cable in my bag, and no change.

Hello everyone, I recently bought a Thinkpad X1 Extreme and I am now locking for a suitable Thunderbolt 3 dock. Although I've read a lot of posts about various docks I am still a little consfused about which one to choose. It seems like the following ones would all work with the X1 Extreme:1. Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W:https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...2. ThinkPad Thunderbolt 3 Workstation Dock (170W):https://www.lenovo.com/ca/en/accessories-and-monitors/docking/universal-cable-docks-thunderbolt/Thun...3. ThinkPad Thunderbolt 3 Workstation Dock (230W):https://www.lenovo.com/ca/en/accessories-and-monitors/top-tech/Thunderbolt-WS-230W-dock-US/p/40AN023... Please correct me if I am wrong but to me it seems as if the only difference between these docks is that the workstation ones come with two AC adapters each and a special Thunderbolt/Power cable to avoid using two different cables. Or are there any other technical differences? So if I am okay with a two cable solution couldn't I just use the Lenovo ThinkPad Thunderbolt 3 Dock Gen 2 135W and connect it via Thunderbolt while at the same time use my 135W AC adapter to charge the laptop? Thanks a lot in advance.

Hi all, I have a Thinkpad T580 and a Thunderbolt 3 Dock Gen2. It worked fine until now.I updated the Dock Firmware, and everything worked. I updated the BIOS from 1.21 to 1.22, and Thunderbolt is not working anymore. Were I work we have many Lenovo Laptops and Docks. I tried another Dock, but the thunderbolt software does not show a connected device. I reflashed the 1.21 BIOS version, but thunderbolt stays broken. How could that happen?I even set the Thunderbolt Security to "no Security" in BIOS, thinking it might have broke security, but no, does not work. When I plug it into USB-C it works, of course. But this way I only have 10GBit/s for everything, not 40Gbit/s like with Thunderbolt. That means not all of my monitors do work and bandwidth is limited. Any ideas how to remedy the situation? Best, maybeapreacher

First... long time T series user going back to the initial ones. Had been using a T520 up until I finally gave in and purchased a T580 over the BF in July sale. Since I have been using a dock for a long time and like the convenience factor I got the Pro Dock (40AH0135US) to go along with the T580. Long story short... the first T580 arrives with a blown system board. I send it back and 11 days later another T580 arrives. This one boots and has no issues off the dock. It's fast and definitely an upgrade from the T520. First thing I notice in placing it on the dock is that the side mount process is tedious. Reading other posts seems to confirm that experience. It's nowhere near as well engineered as the bottom dock solution and I spend more time trying to insert the dock mechanism than I ever had with the legacy dock solutions. I eventually get things perfectly aligned and power on. Right off the neither external monitor is working. I have two Dell UHD monitors connected to the DP's on the dock and neither comes on. I mess with the cables and nothing, I take the T580 off and re-insert... nothing. I call Lenovo and without even trying to diagnose the issue they issue an RMA for the dock. I get another dock 2 days later and this one works for exactly 1 day. The external monitors work and then 10 hours later when I come home from my job and place the T580 on the dock they don't work. Nothing changes but somehow things are back to not working again. To be clear at no point from powe... Read more

Hi there,  I've been experiencing issues with both Thinkpad T580's and 5th/6th Gen X1 Carbons. Basically any model that has USB-C/Thunberbolt connectivity.  I have had users report that their laptops either connected to their docking station or power adaptor  do not charge. Windows reports "Plugged in, Not charging", and power drops. The dock does not appear to work, external screens, network etc.  When disconnected from the power source or dock, the orange power light on the left site where the USB-C connector is stays on. This is the light that comes on when charging. When the laptop is shut down, the same orange light stays on.  The work around I've found is to go into the BIOS, Power settings, Disconnect the internal battery. (External battery needs to be removed for the T series). After selecting this, the laptop powers off and the orange charging light goes out. Once reconnected to a power source, the laptop will power on, work with the dock and properly charge.  I have encountered this on multiple T580's and multiple X1 Carbons. I've attempted to run the System Update utility (excellent app btw) and made sure BIOS and Thunderbolt firmware etc is up to date, yet the issue still persists. Logging into the BIOS and disconnecting the internal battery is not a viable solution.  Is there a solution for this, and are Lenovo aware of this issue?  Thanks,Adam

 My T580 suddenly one day stopped reading my external USB-C hard drive, I tried updating the drivers and several other suggested repairs with none of them working. The power light on the drive would come on but the computer didn't read it, verified with a second drive and they both work on my other computers. Looking at the timeline, I realized that this happened while the computer was still within it's warranty period, but I was busy and just let the problem go. Then two weeks later the computer just shut down on me and after letting it sit with the lid closed for a while, it was able to restart and I got a warning message at the BIOS screen that "The Power Adapter is of lower wattage than the one supplied with the machine" or something along those lines. Once booted up I was able to see that battery nuber one was fully depleted to 2% and the 2nd battery was at 99%, it then shut down on me again. I ordered a replacement power adapter to test and got the same message and the same symptoms, the computer would basically trickle charge at a rate slower than it consumed power, at this point I finally called customer service and started a repair ticket, this is when they told me that the computer was three weeks out of warranty....I send it in and a week later recieve a repair estimate of $589 to replace the whole motherboard. I called right back and complained that this computer was having problems before the warranty was up and was simply told it was out of warran...

I found this post (https://forums.lenovo.com/t5/ThinkPad-T400-T500-and-newer-T/How-many-DisplayPorts-are-available-on-t...) that seems to indicate that this cannot be done, but it doesn't make sense since the dock utilizes two USB-C connections from the T580.

I got my new T580 today, and with it the Ultra Docking Station.It generally works fine except for some minor issues with my monitor still needing DVI, but that is easily solveable. The one big issue I have with it is my mouse:Moving it in circles shows freezes every few seconds, for up to a few seconds at a time! The mouse is practically unuseable as it is.It's a Logitech G500 mouse. Connecting it to one of the Laptops USB ports works makes it work just fine.Connecting one of our cheap default Microsoft mice to the dock also works just fine, but I'd really rather use my Logitech. I tried updating all the firmwares and drivers(OS in use is Windows 10 64bit), but nothing made any difference. The mouse is not only freezing, but judging by the constant device disconnect/connect sounds also completely reconnects every like 30-60 seconds. Using a USB event viewer confirmed that it is indeed the mouse being reconnected.

Hi,
I tried the Dell TB16 Dock which I’m totally unhappy with (noisy, too short cable, USB not working reliably) as well as the Belkin Thunderbolt 3 Dock. My laptop is a Precision 5510.
The Belkin works perfectly with the exception that it does not charge my laptop. The Belkin Thunderbolt 3 delivers 85W according to specification. This is less than the Dell Dock but it should be sufficient to (at least slowly) charge my laptop. To my understanding, the laptop and dock should negotiate the power and agree on 85W.
QUESTION:
- Does anyone know how to make the laptop accept power from the Belkin dock?
- Does anyone know an alternative Thunderbolt 3 dock that is accepted by the Dell laptop?
Thanks everyone!

Hi All, I recently received a Lenovo P53 for work along with a Thunderbolt 3 Gen 2 Workstation dock. I am having an issue with the docking station. It came with two power adapters, a 65W and a 230W, and right now when I plug in the 230W adapter the dock charges my computer but won't turn on the actual dock and run anything through it. But when I have the 65W adapter connected it will run the dock itself and I plug it into the laptop and it powers all of the screens, but it won't charge my laptop. I can't seem to figure out how to get my 230W adapter to power the whole dock like I think it should be. Any help would be greatly appreciated!

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?
