Well you could look here: http://www.ubuntu.com/certification/desktop/

But your laptop is already certified there, the sleep thing has been around in linux for a long time and the only thing is to make sure it goes to sleep before you put it away or shut it down when you are done.

Battery life again isn't going to improve with another laptop windows should be better for pretty much every supported laptop, you could look into buying a bigger battery maybe?

You could try System76 but I don't know that they will be better than an x220

I used a System 76 machine (pangolin) for two years. It was great, except battery life was never more than 1.5hrs. That's pretty bad for a 15" laptop.

If the machine will always be plugged in, I recommend System 76. But if battery life is an issue, there are better laptops out there.
