Cool, at least it is supported. I know someone with that got a brand new Lenovo about a year ago and had loads of issues with it, even with the bleeding edge kernels in Arch. > Does anyone know what I might be missing in my kernel config? > Or does anyone also have a X1 Carbon 3rd generation and would like to > share the .config with me? Do you have SUSPEND=y (just checking)? Other things that I can see related to suspend are SUSPEND_FREEZER, ACPI_SLEEP, APM_IGNORE_USER_SUSPEND, and a bunch of Thinkpad/Lenovo related options. I do not have suspend enabled on my laptop, so take this with a grain of salt. If you want to search various kernel options, you can run `make menuconfig` in the source directory and use '/' (forward slash) to search just like you're in `less'. Alec
