Yoga 370 no display when connected to Lenovo USB-C to Displayport Adapter

Q: Yoga 370 no display when connected to Lenovo USB-C to Displayport Adapter

Hi Everyone, Recently purchased Yoga 370 with USB-C to Displayport adapter (FRU 03X7204) to connect to my DELL U2412M. When I plugged in the adapter to the Yoga, it detects as "USB Billboard Device". Google tells me that it means something went wrong when during the handshake between dongle and notebook for initializing DP alternate display mode. I have nothing else to go on because there is no error message displayed... I have switched TB 3 mode to Displayport and USB in BIOS and that did not work. Anyone has any ideas? Much appreciated in advance.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Everything is working except - no sound via monitor.  Have updated audio drivers,  Suggestions??

A:Yoga X1 ThinkPad thunderbolt LG Monitor Connected via DisplayPort - No Sound

You might need to enable it. 
 
With the monitor connected, turned on and displaying your computer's desktop:
 
Right click on the speaker icon in the taskbar and select "playback devices." 
 
In the white area of the dialog box, right click and make sure both "show disabled devices" and "show disconnected devices" are both checked.
 
Right click on the various playback devices to make sure they're all enabled. 
 
If you start something with audio, you should see the little green "meters" bouncing on one of the devices. Right click that device and set it to default.

I have a Lenovo Yoga 2 Pro hooked to a Think Pad 3.0 Dock and use two external Dell Monitors.  Everything worked fine for quite awhile, then one day while working the external monitors stopped and are no longer identified or detected.   I replaced all of the cables and insured all of the drivers are up-to-date.  I also confirmed that both monitors still work on another computer.  I borrowed another Think Pad Dock to see if the dock may have fried, but the new one does not work either.Any suggestions?  Thanks.

Hi Guys, I have a Lenovo Yoga 2 laptop. This is the second time I have had issues with the WiFi dropping out frequently.  The first time was when I first downloaded windows 10 - I downloaded a new driver from the Lenovo website and everything worked perfectly.  The last couple of months it has been playing up again. My phone and any other devices will be connected to the internet however my laptop will repeatedly disconnect from the internet, this happens a ridiculous amount of times everyday - and it's not just my home wifi! Im currently at my university library and it does the same thing. It just drops out randomly and says "not connected - no connects are available" I have to keep restarting my laptop for it to reconnect to the internet (I know that's probably not the best thing to do but it's the only thing that sometimes works). I've tried uninstalling and reinstalling the driver software, I've scanned for hardware changes and nothing comes up?? Has anyone got any ideas on anything else I could try?  Thank you all!

Hello, recently the wireless symbol in the taskbar disappeared from time to time and connection via WiFi was not possible but connection via LAN cable was possible.I checked the network and internet settings and a WiFi-adapter was not listed anymore.I checked the device manager of my Lenovo Yoga 2 Pro but the "Intel (R) Wireless-N 7260" device disappeared.Only when I choosed "Show faded out devices" I saw the "Intel (R) Wireless-N 7260" device.When I choose Properties from "Intel (R) Wireless-N 7260" this message appears:  "This device is not connected to the computer (Code 45)".Some times when this problem occured I could bring the device to work by a hard reset. It also happened a few times that the laptop did not boot and a hard reset solved the problem of not booting and the not connected wireless module.Now the device is gone again but a hard reset does not solve the problem anymore. What's remarkable is that often before the problem occured I could surf the web intensively via WiFi then I closed the laptop cover (Hibernation mode is set) but when I waked it up again WiFi was gone. The newest Intel driver for the device has been installed after an OS upgrade from Windows 8.1 to Windows 10.

So here is a new one:  I have a Yoga 910 that has had many networking issues. It appears that if I unplug the computer from my USB-C dock (the dock still has power), the dock network connection freezes my router. This is repeatable, and annoying. As soon as I powered down the dock (by unplugging it), the router starts working. I am using an ASUS RT-AC5300 "mother of all routers" (when I bought it), and it has been rock solid until I started with my new Yoga. It is running the latest firmware, and I have updated the firmware on the dock as well. Ideas?

I have an Lenovo Yoga 3 Pro and can't find a 12V DC car adapter anywhere. I have just bought an Lenovo 65W DC Travel adapter, but it dosn't have the right connecton til the notebook (USB). Is there a slim tip to USB converter or any other solution to connect my notebook to 12 Volt DC?

A:Lenovo Yoga 3 Pro and need a Travel / Car adapter

Welcome to the forum.
 
From what I can see this system uses a proprietary USB-like connector with a small notch on one corner. I'm not aware of a car charger for this format, either from Lenovo or from third parties. This blog explains some of the issues: UPDATE: Lenovo Yoga 3 Pro External Battery and Car adapter. See Update April 19, 2015.
 
Another option would be a 12VDC-to-110/240VAC car inverter, then use the standard AC charger that came with the Yoga 3 Pro. That is, of course, less efficient.

Hello everyone, I purchased Lenovo Yoga 900 Ideapad and I am currently using it in India. The power adapter seems to have gone bad and I wasn't able to charge the laptop with the given adapter.  Since the laptop is under warranty, I contacted the warranty help line only to know that I need to take the laptop to the service center. At a service center, no one really knew how the USB 3.0 charging port works and couldn't check whether the cable was short or the adapter had gone bad. Anyhow, they decided to replace it under warranty but again, they weren't sure when and if the replacement would arrive (as it depends on the inventory levels with Lenovo India).  An exclusive Lenovo shop then offered me an original Lenovo power adapter with USB 3.0 charging at USD 70 but only when it got delivered, I see that it is 40W and not 65W like the original one I had.  65W adapter - the USB 3.0 connecter (one which connects the laptop) is orange. The wall adapter doesn't heat up while laptop is charging.40W adapter - the USB 3.0 connecter is yellow. The wall adapter heats up quite a lot while the laptop is charging.  The Lenovo store representative has assured me that this is the right adapter but somehow I am not convinced.  Can the community throw some light on this:- Is it safe to use a 40W adapter for a 65W specification?- Is there any way I can get the adapter replaced by Lenovo US (I can ship the faulty adapter to US)?- I...

I'm not sure if I'm missing something here.  We purchased a Microsoft Wireless Display Adapter, and it appears to be working.  The issue we are having is when my laptop is connected to the wifi network (LAN), it doesn't find the wireless adapter.
 If I disconnect from the wifi network, it finds the wireless adapter and connects fine.  It appears that my laptop isn't creating a Wifi Direct connection when searching for the Adapter and therefore can't connect to the wireless adapter unless
the wifi is disconnected and therefore available.  Does anyone have experience with this, and ideas?
I haven't yet tried other laptops, but we did test with an Andriod phone, and that connected fine, and was also connected to the Wifi (LAN) at the same time. The laptop is Windows 8.1, and appears to be miracast compliant. (the search for wireless display
button is available)

Sound was working when I went to bed, in the morning it wasn't.  Popup on speaker icon in system tray says "no audio output device is installed." Updated all drivers using iObit Driver scanner.  When that didn't find an audio adapter I rand the driver scanner on the Lenovo support site and it said no new drivers were needed.  Ran recovery from the startup and chose option to completely wipe the hard drive, files, progrmas etc. and install Windows 10 to factory settings - still no sound adapter. Saw a similar forum post with a link to a Reatek driver so installed it - no change.  Also followed instructions to uninstall sound in device manager but it wasn't there to uninstall.

I am using a usb-c to hdmi adapter to output to a TV but the black levels look washed out. I had no issues with the same TV and a previous laptop that had a dedicated hdmi port. In the intel graphics settings usually there is a "quantization range" setting to change color space between RGB Limited and RGB Full if the intel graphics is driving the hdmi port. However, in this case, there is no hdmi port but instead a usb-c to hdmi adapter, thus the quantization range setting is missing. I've had the same issue before on a previous laptop with usb-c.

Hi all, We have a Lenovo Yoga 500-14ISK and a Samsung LED monitor (tried with other monitor too) connected with hdmi cable. After installed the graphic drivers the external display worked properly for 2-3 weeks. But then it became unseen for the notebook. I've reinstalled the driver and it worked again for 2-3 weeks. Last time I've installed the updated driver but the last week the problem appeared again. As usual I've installed the driver and after the 3rd restart it works again, but I don't know how long. Have You any idea what's wrong here? Thank You in advance,Zoltán
