Q: What are the Keys to push for "Apple-Check on functionality of MacBookPro"?
My six months old Mac Book Pro worked well until yesterday,
I shut it down and some hours later (after having placed it in my safe)
I could not restart Yosemite OS X:
1. Electric Power On - works - the MacBook is on, but
2. MacBookPro shows a dark empty screen: nothing on the screen and not going into the process of loading Yosemite OS X.
3. please send me the link to the Apple-Keys to push, to let Apple.com check my MacBookPro.
Support me with the Keys for "Apple-Checks my MacBook on functionality", please.
MacBook Pro, OS X Yosemite (10.10.1), null
