Also, since I'm from Europe, I'm used to a map with Europe on the center. Since Lenovo didn't offer a version of the map with Europe in the center I ended up concatenating two maps, so that I could crop it at my will. The result was a big 3000px x 1200px image.
I didn't like that much the wallpaper I made, so I returned to my beloved Thinkdots, but I guessed someone else might want give it a try.
I've uploaded the original .PSD files I created, in case someone wants to make some modifications.
Grab the .PSDs here.
Here are the concatenated versions of the map (just crop them):
