my macbook pro wont turn on

I know it has been a while since this got posted but I recently had the same problem and I'm sure others will come here for help. Green charge light but my MacBook Pro wouldn't turn on. I pressed and held the power button for 10 seconds then waited about 1 second then pushed the power button briefly. It came on right away.

IM having exact same problem any suggestions

I also am experiencing the same issues as described starting only this morning. It was purchased December '12, and have had zero issues until now.

genius bar appointment determined it's likely an issue with video card. Because i could hear start-up chime but had no screen or monitor display, the video card is most likely faulty component.

My Macbookpro is fully charged but won't turn on?
