Yoga 900-13ISK usb-c port not workingwith Dell P2421C monitor

2021-02-22, 15:55 PM

I have a lenovo yoga 900-13ISK, serial number: xxxxx, product number: 80MK000WMZ. I tried to connect this to a dell monitor P2421DC via the usb-c cable that came with the monitor. It doesn't work and the error message on the monitor says "no usb type-c signal from your device". Can anybody help me? 

 

thank you

Hello, I have a Lenovo yoga 500 and have a similar issue and more.

1. None of my 3 usb ports work:- but Device manager says 'working well'.

2. My card reader wiped several adcards then no longer works.

3. And worst of all: My yoga-14ISK screen flickers so badly when unplugged from electricity that it is unusable.

 

Any ideas how to solve these issues?

I've checked all driver updates.

And system declares them working.

Thanks.

@ITALCHUX 

 

You should probably start your own thread as this is a different model with a likely different issue. I suspect the OP's issue is a USB-C video implementation difference between the 900, which was designed in the early days of USB-C and the monitor, which came out much later. There are a lot of posts about earlier computers having issues with USB-C docks. I haven't had time to research it further and Lenovo techs probably can spot that faster than I.

 

As one of our mods puts it, "USB-C: Just cuz it fits don't mean it works."
