Macbook Air Haswell-doesn't wake up
As mentioned in the title, literally, my Macbook Air doesn't wake up occasionally.
Sometimes (3 or 4 times out of 3-50) when i close the lid of my notebook and open, nothing appears but the black screen appears and only the light of the keyboard glows. No input(including trackpad and the keyboard) helps get out of the black screen and the only thing i should do is to turn the power of and turn it on again.
It seems that some users using Macbook Air Haswell and some Macbook Pro models. And some explains it happens because of chrome browser. I purchased this notebook about a week ago and I can get a new one by contacting Apple Store. Should I get a new one and see if it happens? or should i just restore my notebook and see if it happens again? It's quite confusing and frustrating.
MacBook Air (13-inch Mid 2013), OS X Mavericks (10.9.1), 128GB (Sandisk SSD) SSD, 4GB RAM
