HELP! My macbook pro retina not charging
I left my macbook pro 15" retina a while ago, then it turned to sleep mode. When I came back, I noticed that the power connector have no lights (green, orange), so i turned on my mac, but I noticed that the battery percentage reduced to 80% which means that the charger isn't working. So I went to internet to look for possible solutions and so I tried the PRAM and the SMC, but still its not working. Hope you could help me before it drains out. Thanks!
MacBook Pro with Retina display, OS X Mavericks (10.9.2)
