Whenever I go to log in after my Macbook Air has gone to sleep, whether by it sitting long enough or me closing it, the whole screen seems to be shifted to the right by more than an inch! This problem goes away the moment I've logged in. This recently started happening, even after the Yosemite update it was fine to begin with, also this isn't an old laptop, not even a year yet. No extensive damage beside one drop, but the screen was fine after that aswell. Any help or tips would be appreciated, thanks!
