Re: Yoga 920 USB C to HDMI not working

2018-01-22, 16:19 PM

Last week I taught a training class and had the USB-C, C106 connected from roughly 8AM until 5PM Tuesday-Thursday and 8AM until 2PM Friday. I was not using pass through power and the only thing connected was HDMI which I had no issues with. Mouse - Microsoft Arc Moue Surface edition Bluetooth - worked correctly for me

Re: Yoga 920 USB C to HDMI not working

2018-01-25, 6:49 AM

Same issue as others on the thread: usb-c to HDMI not working on brand new Yoga 920. I tried several brands of high quality dongles that work on all Yoga 910 machines in the office.

 

Several painful conversations with Lenovo customer "service" who informed me that I was the problem - and only Lenovo dongles will work with machine (though not sold at the point of sale where I bought machine). Even though this is in clear breach of Australian consumer law which states product must do what the specs say it does i.e. USB = universal serial bus and this Yoga 920 doesn't work with non Lenovo dongles, no one at Lenovo cares. Told me I was dumb for expecting the 'universal' in USB to mean it's actually universal.

 

So reluctantly bought the Lenovo dongles, arrived late, took 10 days to deliver to metro Sydney. Plug in the new dongles (travel and one:one usb-c to HDMI). Kinda worked once on the one:one Lenovo dongle, doesn't work on the Lenovo travel dongle.

 

Finally speak to someone there who was helpful issues a DOA number for a return (or refund). Since I was pot committed on the accessories rolled the dice again. The new version works perfectly, first time! ON ALL DONGLES inc. the SATECHI.

 

So if you have this problem accept nothing less than a replacement machine - your machine isn't working as stated by Lenovo. Suspect Lenovo have this as a known fault on the Yoga 920.

The only problem I have is the USB-C Thunderbolt ports aren't hot when the machine is off.  That's one of the advertised features.  Anyone else have the problem.  Easy to figure out if you have a cable to plug your phone in with.  With the computer off, plug the phone in to either of the Thunderbolt ports and see if the phone starts charging.

 

As with the early HDMI problems, they want it sent back for repair.

Are you sure about that?  I understood that the USB 3.0 Port was the always-on port for charging phones, not the Thunderbolt USB-C ports.  The USB 3.0 port is situated on the right side of the system towards the rear.

Hi All together,

had the same issue also posted it on this Chat and found a quick easy solution that hasn't been posted here as it seems.

DOWNLOAD LENOVO VANTAGE from Windows store
RUN THE UPDATE because there is an update that affects the USB-C Port
USE ANY USB-C to HDMI I am now using a cheap multiport adapter having SD, USB3 and HDMI and it works perfect - have returned all the other expensive ones that I tried - they are not necessary

 

Hopefully, this helps

@Andy_Lenovo: I have a Thunderbolt to Lightning cable and have used it to charge my phone while the computer was off and I was on the train. This was before the HDMI driver was updated so HDMI works and on a previous computer that was returned per Tech Support.
Tech Support has issued a return for my current computer for repair of the USB-C ports.

Hi ZRon,

 

Thanks for that; i couldn't find anything about that in the documentation, only that the USB 3.0 connector provided power for charging.  I'll go back and check with the engineers.
