So recently the bottom 1/3 of my screen gets corrupted or just doesn't display quite right, by pivoting the screen or pressing on parts of the top gently I can sometimes fix it. The problem is becoming more prevalent and I am not sure what I should do. I am not sure if it would happen if I took it to an Apple store and it didn't show up for demonstration, furthermore what happens to the data on the drive if they do end up taking it for repairs/replacement? (I have had the laptop for ~6 months) What should I do?
