So a little bit ago fedex dropped off my macbook pro 13 inch refurb. I turn it on, get to the white screen with the apple logo....multiple 5-7dark pixels on my screen! WTF?! I called Apple care, told them the issue. I get told to do Control,shift,option, and power and hold them down for five seconds...Did that, still there. Told me to do software update...still there. He told me I could call my local apple store to find out if they can swap it out. I called them, guy there told me they don't do that, and i should call the apple care again. I called back, they told me I can do an exchange. That's cool. Now here I am waiting for a damn label to get to my email (up to 24 hours), then take it to fedex and ship it back. then up to 24 hours later, they will ship out a new one. I most likely wont get it to weds now. How can I figure out if they are stuck or dead? They don't show up on black, just white.
