So on Thursday, I came home to boot up my computer as usual when I noticed something funny. The internal display wouldn't turn on. I heard the disc drive turning on, and the LED's on the caps lock and num lock worked. So naturally, I was scared since I haven't had a backup in a while. I tried to look online for answers but came across a support page from Apple with instructions on how to fix it. I tried most of them and they didn't work, unfortunately. After various tests, I realized that it could have been the Nvidia problem that people have been experiencing. I called Apple and they had me run through basically the same things. I reset the PRAM and other various things and nothing worked. At last, I decided that I should bring it in to Apple for repairs...It was the start of my Winter Vacation so that was a bummer. It would take a week too! So after it sitting there for a half hour, I decided to try to boot it for the last time. It worked. I was so amazed!!! How could this be?? I immediately backed up my files and such and waited for it to crash or something. It didn't. I haven't shut off my computer in 2 days because of the possibility of it dying on me. I have a few questions that I hope some of you can answer. Has this ever happened to you before? How long does a Macbook usually take to fix? Will my MacBook Pro eventually need fixing? Is my laptop affected by the "nVidia chip"? Thanks for your time and I'm dying to hear your response.
