Yoga C740 is not charged by i-tec USB-C Metal 4K Docking Station w/ PD

2019-11-23, 21:16 PM

My new laptop Yoga C740 is not charged by usb-c i-tec docking station. All drivers are installed after docking is plugged and everything seems to work except charging. Is there any protection from using third party docking stations? The docking station has 85W, it should be enough, because original power adapter has only 65W.

 

I've updated BIOS and all available drivers via Lenovo Vantage. Battery safety feature is off.

 

Please, could you help?

 

Thank you.

Thanks for that.

 

The page you linked to seems to indicate a liklihood of PD incompatibility, which we frequently see with third-party devices. IMO, they test them with a Macbook and maybe one other brand and ship them out the door.  I will edit your thread title to add the model in case another C740 user has experience with it. In the meantime, you can apparently email support@itecproduct.com to see if they've tested it with a C740.
