so i got a MBP 13" from microcenter last week and i didnt really examine it after i got it. but i fell off my chair today and i noticed there is a gap about 1 millimeter at the top left side. that area also gets warm when im using the computer. is this normal or is this caused by expanding battery???? also, in the place where its like a black bar, if you look up closely, you can kinda see the inside. i dont know if this is suppose to be like this. i cant return it anymore because microcenter has a 7 day return policy. should i bring it to apple store?
