lenovo also hides s3 support so it makes it impossible to install anything other than windows and sleep/wake reliably. Never buying lenovos again.

There's a meaningful distinction between "Linux doesn't support certain firmware functionality well" (as is still, sadly, the case for s0ix) and "Linux is literally unable to boot unless firmware configuration is modified", which is the case here

What? I literally had to disable Linux compatibility in Lenovo BIOS' to get deep sleep on Linux working. It's not hidden?
