Hi, I just got a brand new MBP 17 for work at my office today. I left it on for 10-15 min to do something else, when I got back, the screen was dark. I thought it went to "sleep" so I tried to "wake" it up by pressing a key. The screen came back and immediately went to dark again. The screen was on but it was so dark, I could still see something but I couldn't see the mouse cursor. I tried to reboot the machine, tried to reset SMC(???), nothing helped. I haven't used the machine for more than 1 hour, but I did remember I was asked to do some kind of system update which I did. Does anyone know how to fix this issue? I am thinking to visit a nearby Apple store tomorrow to see I can get a replacement, but thing is that my IT purchased it from PCMall (along with AppleCare - I was going to install it but the screen was too dark to do so), can I get a replacement at Apple store, or I have to ask my IT to sent back to PCMall for a replacement. Thanks!
