macbook pro 2013 will not start only fan
I left my Mac charging over night. I had not turned it off but had put it on sleep before closing it. When I tried to use it this morning it did not turn on, only the fan started running and does not turn off. Checked battery levels on side and it does not have any lights on even though it was completely charged. The front bottom on light is off as well. When I reconnect the charger it does not light up. Tried to use shift cntrl option per but nothing happens. Please advise on what to do. I did install Yosemite as my OS a few days ago.
MacBook Pro (13-inch Mid 2012), iOS 8.1, yosemite
