My sister has a Macbook Pro that she bought from the Apple Store in May (new). She calls me tonight to tell me that it won't boot up and would like me to help her. I am hoping to get some ideas here. She said that she left it on overnight last night. When she woke up this morning, the computer was still on but the screen wouldn't come back on. It was almost like it was stuck in sleep mode or something. After trying to tap the keyboard and mouse to get the screen to come on, she finally did a forced shut down using the power button. Now, she says that the computer won't turn on at all. Any ideas are GREATLY appreciated on how to troubleshoot this. Thanks!
