WORKJING DELL 4K Alienware 15 R2 Intel Core i7-6700HQ 2.60 GHz 1TB 16GB (USED).  Has 970M GPU, repasted with new thermal paste. The number 2 key works but the keycap fell off, it works perfectly fine though but instead of pressing on a keycap you press on the rubber dome. The stickers can be taken off if requested.
