I have been buying X1 carbons since gen 1 and I just recieved 5 Gen 4 carbons. We image all our X1's prior to deployment and I am disapointed that they are no longer including the eithernet dongle with the laptop and they changed the port to the a new onelink plus so none of my old dongles will work. I have a couple of lenovo USB dongles that I use to use to image the gen 1 X1 carbons. I am tying to use the usb dongle but it doesn't get regconized by the bios. Any ideas? I have orderned the a new onelink plus adapter but they are back ordered everywhere and I have 5 X1's I need to get imaged.
Solved! Go to Solution.

If you're trying to load after installing an OS, use this driver:

I am trying to PXE boot the device to image so the driver won't help. The old X1's would see the usb dongle as a boot device allow us to image the laptop. These new X1's don't see the dongle from the bios.

BIOS V: 1.14 shows these fixes:
- Fixed an issue where Ethernet LAN Option ROM might not work properly with PoE
- Fixed an issue where 32-bit aplication might not work in command prompt.
- Fixed an issue where "Boot Order Lock" in ThinkPad Setup cannot be changed
- Fixed an issue where "Ethernet LAN Option ROM" in ThinkPad Setup did not work.
I have no other ideas, other than wait for the onelink plus adapter

I don't have a pxe image to test and I don't have a gen 4 carbon, but I have the USB adapter and a ThinkPad Yoga 260, which has the same CPU options, so the BIOS may be similar. In the BIOS under config/USB, when I set the option for USB UEFI BIOS support to "enabled" and plug in the dongle, the light on my hub turns on, as if it is connected.

Tried that but it still doen't see the adapter. Maybe it has something to do with the USB 3 ports. On our old X1 the dongle only workingin the usb 2 port but the gen 4 only has USB 3 ports.

I guess I can't add anything. BTW, the Yoga 260 I tried is also only USB 3.0

I might also set the boot options to be "both, legacy first" and try that, and plan to set it back later.

Think Engineering has provided information that may assist you.
The BIOS for the X1 Carbon 4th Gen does not support the earlier generation of the USB-Ethernet dongle device for PXE boot. It appears from your comments that you are using Lenovo USB2.0 Ethernet Adapter P/N: 0A36322.
Lenovo recommends using ThinkPad USB3.0 Ethernet Adapter P/N: 4X90E51405 to perform a PXE boot on the X1 Carbon 4th Gen model. It can be purchased here:http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:item.detail?...
