Yes and probably also the x1 from the same generation, etc. The problems are:

1) Do we want to enable this on all without even a smoke-test ?
2) We need to have the DMI strings for these to add entries (I'm pretty sure we've those in
some old bugs / patches)

Tonight I should be able to loan an x240 for a few hours then I'll test to see if it indeed too
is too insensitive by default (according to the interwebs it is) and add an entry for it too.

Regards,

Hans
