I have a sony vaio z VPCZ217GG/X laptop which I bought 1 year ago. Just a slight minor issue, the palmrest area of laptop got darker as compare to the original color of the laptop. I think it slightly got discolored. Actually most of the day I keep working on my laptop so every time I keep it open and do my things. Even when I am not doing anything, I keep my hand on the rest area. Must be that caused the problem
