It looks like a typical thinkpad rubber back, but with the x1's "carbon fiber" design cutting through it with a wide diagonal line. Google only gives standard rubber backs. Anyone have any idea what this version of the design is called?
Looks custom. It seems unlikely that Lenovo would offer this.
Run your fingernail across the transition in each direction. Is the carbon fiber part higher than the rubber coating, or lower?
I really doubt it's actually carbon fibre why would you put carbon fibre on a laptop made of plastic? The plastic would deform from impact before the carbon fibre would, so it would have no benefit.
Perhaps Lenovo decided that they wanted to add a single design element to their laptop in a brave new move to be interesting.
The lid on many modern Thinkpads is carbon fiber composite (non woven CF). And the palmrest area is made of magnesium.
I am 100% certain that this is true for at least my T14S Gen 1.
higher. i doubt it's a sticker though, it's almost like its intergrated into the case.
fyi, i bought it from a local store called e-byte.gr, but the keyboard is nordic (probably swedish)
