"Dell XPS" is too generic a term to be useful. I've got an old XPS 13 which works perfectly; I also got a newer XPS 15 (top of the line, 4500€) which never managed to sleep correctly (thanks to Intel s0ix hybrid-suspend) and often overheated in the bag. I got rid of the latter after 1 year, it was a mess to use.
