Ideapad 720s 13IKB - Thunderbolt port not working

Q: Ideapad 720s 13IKB - Thunderbolt port not working

I have only had this laptop for a month or so, but the Thunderbolt usb-c port stopped working. I can still use this port to charge my laptop, but it won't connect to any other devices nor output video to an external monitor. Has anyone encountered this problem before? Does it mean I need to send my computer back for a repair? Thanks.

Hello all, I have a problem with my Thunderbolt 3. I had to do a clean install of windows 10. I used the built-in function of windows 10. And did a hard reset, so no bloatware survived. After the reset everything worked well, but the thunderbolt software did not install itself, like the rest did. I downloaded the driver and software from the support page for my device. (here: https://pcsupport.lenovo.com/nl/nl/products/laptops-and-netbooks/700-series/720s-13ikb-type-81bv/81b...). But after this it still doesn't work..! I think I'm missing the firmware part.(Like this for the thinkpad x1 carbon: https://support.lenovo.com/nl/nl/downloads/ds120382) It looks like this:How it should look Print Screen Thunderbolt SoftwareI contacted Lenovo support here in The Netherlands but he said I had to do a reset. I know this isn't gonna work, because it'll just reset itself to standard Windows. And then i still don't have the firmware..Anybody an idea or know where I could maybe get the firmware?

Hi,I have new 720s - 13IKB with 8th gen processor and I'm trying to connect HDMI through USB C dock. I have Minix Neo C and iTec(with usb and HDMI). Both are working fine with Samsung S8, Asus Tranformer Pro 3 and Macbook Pro with LCD diplay and projector, but I'm not able to make it work with Lenovo at all. It seems that projector is able to recognise something in HDMI because it take few seconds at HDMI before it ignore it. I updated all drivers. I even tried VGA driver directly form Intel.Is there any known issue with it or any list of supported docks? I found tthat there was some update for Yoga 920 solving similar issue..

My IdeaPad, suddenly will not turn on. Pressing the Power button, a led on the button is white for about 4 seconds and then turns off. I experience the same if it's running on battery or AC adapter. The led next to the AC adapter is white when the USB C charging cable is attached. I've tried holding down the Power button for +15 seconds with and without the AC adapter attached. Any ideas for further troubleshooting before returning the laptop for repair? Thanks, -Martin

Hi all, I just received the laptop mentioned above... and already stumpled other the very fancy soundy fan... it turns on early and it has a nice high frequency noise... very bad. I am used to the Yoga 720 and there a silent mode which was very helpful as it reduced the need of the fan overall (not heavy usage here). 2nd issue: Installed newest bios... and now the CPU is stuck at 1,5 GHZ and below... what the hell? I was wondering how that can be true (red it before in a test), that a bios available for quite some time can have such an issue. Lenovo? I changed power modes, tried own energy plans and so on... stuck at 1,5 GHZ. Best,Andy

Hi all,Last October I bought an Ideapad 720s 13IKB, and ever since I always had problems with the touchpad. Sometimes it works, sometimes it gets blocked, sometimes even the cursor doesn't show. I've surfed the Internet and tried all the possible solutions:- Checked for any possible update (both Windows' and the Lenovo's driver);- Uninstalled the driver and rebooted the laptop in order to let it find and install the driver by itself;- Tried several types and versions of drivers;- Rebooted I-don't-know-how-many-times the laptop, hoping that things will get better;- And yes, I checked the touchpad is enabled through the F6 button. I don't think it is a hardware problem, since the touchpad sometimes works I'm sick and tired of this problem, since the computer is new and it costed a little fortune and I need it everyday since I use it for work. Any saviour?

Hello, I have a pretty new Yoga 920-13IKB.  The USB Type A port just stopped working out of the blue yesterday.  I tried the normal stuff like deleting the usb entries in device manager, disabling fastboot and trying different devices, but nothing is recognized.  I have a USB C to USB A adapter and when I plug a USB A device into the laptop via the USB C port/adapter, that does work fine.  The USB A port does charge my phone though, so it's not totally dead. Anything else I can check on the software side?  It certainly seems like a hardware issue to me. As far as warranty support, I do have Microcenter nearby.  How does support with them work?  It looks like the USB A assembly is a separate board and is not part of the motherboard, so that should be easily replaceable.  Does Microcenter carry parts like that or do they still send it out for that? Thanks!

Weird enough the graphics seem load faster than the audio...(image plays already, audio kicks in 1-2 sec later)
 
I have already updated the drivers for both Intel Display Audio and Realtek High Definition Audio (SST) and performed the latest Windows update. Couldn't find anything helpful on the forum either.

I'm having issues getting the TB16 to work with the XPS 15 9550. I successfully installed all the drivers in the proper order as documented prior to plugging in the TB16 for the first time.

I've verified that I indeed do have a Thundrerbolt port - there is a Thunderbolt symbol next to the USB-C port.
When I do plug in the TB16 the power button on it will power the system off/on.
I've used a usb-c to Displayport adapter and a usb-c to usb 3.0 adapter with a flash drive. Both worked successfully so the basic functionality of the usb-c port is working.

When I plug in the TB16 I never got an authentication window pop-up. In the Thunderbolt software it shows no attached devices.

The details setting in the Thunderbolt software looks fine, it appears to have the proper driver and firmware levels.

When I check the Thunderbolt driver it says that 'the hardware device is not connected to the computer'.
I'm at a loss - everything looks good except for the fact that nothing happens when I plugin the TB16. I'm wondering if there's a hardware problem with the Thunderbolt controller itself? I'd appreciate any help that anyone can give me.

A:XPS 15 9550 - Thunderbolt port not working - TB16

You might open the Thunderbolt software and set it to allow all devices.  I reset my system and redid the TB16 and it shows the cable and dock as approved devices.
It was not hard for me.  The thunderbolt controller is on the computer.  You show some correct info for that controller, although since I have a 9365, that specific info may be different, but you do show a different controller generation..

Hello.
I have purchased the new XPS 13 2-in-1 laptop.
The Thunderbolt 3 port on the left side of the laptop is not working.
I have also purchased the TB16 dock and it is not recognized at all.
In the Thunderbolt software details, it shows the Controller driver as "Unknown".
I am out of ideas.
I have done the following:
1. Clean install Windows and run all updates.
2. Install all of the latest drivers and Bios updates, in order, according to the official Dell guide for this laptop.
3. Followed guides in this forum and Reddit forums.
4. Had Dell support come in and replace the motherboard.
The TB16 dock is still not detected, nor is any other Thunderbolt or USB-C device connected to the port on the left.
The TB16 dock, however, does charge he laptop and properly shuts it down if I press the power button on the dock.
I have checked the Bios settings, and also tried updates/fixes from Intel. Nothing works. The Thunderbolt firmware update cannot even run because it cannot detect the controller. It still says Controller Driver as unknown.
I have the i7 with 16GB RAM, and 512GB SSD.

A:XPS 13 9365 - Thunderbolt/Power port not working - TB16

So you have loaded the Thunderbolt drivers (firmware and Controller) and it is enabled in the Bios?
There are also Dock Drivers.

Hi,
I myself own an XPS 15 9550 and noticed that I was not getting the full Thunderbolt 3 speedover it's Thunderbolt 3 port. I expected speeds around 2700MB/s, because of the overhead withthe theoretical gross speed of 3870MB/s, but I only ever got 1400MB/s out of it.
I did some digging and found out that none of the XPS notebooks with Thunderbolt 3 are evenable to achieve the full TB3 speeds, because they are only connected with two PCI Express lanes (x2.3).You can read more about this on the following links:Dell Subreddit PostChipset Digging on Forum

Thunderbolt 3 and the promised speeds were the MAIN REASON I even bought this notebook.I feel very cheated here.
