## Questions & Answers

**Q: Will this work with the new 6th X1 Carbon?**
A: It will absolutely NOT work. The 6th Gen Carbon X1 requires this: 
ThinkPad Ethernet Extension Adapter Gen 2
Part Number: 4X90Q84427
Lenovo has redesigned the port, and older adapters will not fit. Unfortunately, Lenovo does not have them in stock, and other sites, namely CDW, are price gauging. CDW wants $39.00 for it. Lenovo's list price is $29.99. They don't know when the part will be readily available (and thus readily available on Amazon). They are not sure why there is such shortage of these adapters. It's probably due to how new the X1 Carbon Gen 6 is.

**Q: How is this better than a standard usb-c ethernet adapter?**
A: It is made for the proprietary port on the Lenovo ThinkPad X1 Carbon so you would not need to tie up a USB port for the standard USB to ethernet adapter.

**Q: Is it compatible with X1 Carbon 5th generation model 2017?**
A: Yes, I have used this on a 5th gen - the connector is the same.

**Q: will this work on my Carbon X. I had the adapter but lost it...previously i bought the 04X6435.  The connectors look the same but I am not sure.**
A: This is specifically for Thinkpad X1 Carbon.
