Yoga 730-13IKB: One of the USB-C ports stopped charging.

The USB-C port closest to the montior will not charge the laptop at all.  The light on the side does not turn on, Windows says I'm on battery power even though the (Lenovo) charger is plugged in.

 

This only happens on the USB-C port closest to the monitor.  The other USB-C port lights up when you plug the charger into it.  Windows will say I'm plugged in.

 

Troubleshooting steps I've already done:

I've updated Windows and all Lenovo drivers (including a BIOS update).

I've run Lenovo diagnostics.  The only error I got was from "Accelerometer Noise," which I'm assuming happened just because I ran the diagnostics in a noisy room.  In other words, unrelated.

I've started the laptop with a Linux Live USB stick plugged in.  Linux Live would not charge from the USB-C port closest to the monitor either.  So it's not a Windows problem.

Just for giggles, I plugged my Samsung Galaxy USB-C charger into the port closest to the monitor... and the charging light lit up.  Windows said I was plugged in.  Switched to the Lenovo charger - again, nothing.

I pulled out my Jackery Supercharge 26800 PD battery pack (compatible with the Yoga 730 and I've never had problem with it).  It works on the USB-C furthest from the monitor.  I plug into the one closest to the monitor and get a connect noise, then an immediate disconnect noise.  Then same problem - no light, no charging.

 

Little help?  I'm concerned that this could be a preview of larger problems.

Hi Woobus,

 

Welcome to the Community Forums.

 

The details you have described here, sufficiently identifies probable hardware port failure specially if you have verified that the ac charger works just fine on other machine and the farthest type C port.

 

I suggest to have this reported to technical support so you guys can create an action plan on this matter.

 

I hope this helps you on how to proceed best.

 

Regards

Thanks! 

 

I tried one more thing before calling technical support: I got out my usb-c to HDMI cable and tried it in both ports.  At first, both ports showed a green display on the secondary monitor.  That made me check the connection on the secondary monitor.  Once I unplugged / replugged on both ends, I got a working (not green) display on the working usb-c port (farthest from the screen), but nothing on the other usb-c (closer to the screen). 

Fortunately, I'm on warranty and Lenovo support said I'm covered.  Time for the ol' Yoga to make a trip to the service center...

Hi

I have the same model and exactly the same problem.

Only the secondary port is charging, the one not intended to use for charging without the outlet logo.

did you solve this or return is the only option. I bought my laptop in USA but are actually in Ecuador

Well, my solution was a warranty repair.  The ports are integrated into the motherboard, so the entire motherboard was replaced.
