macbook pro screen wont turn on.
yesterday, i was using my macbook pro and i noticed it was getting kinda sluggish, from having all sorts of apps and things running all at once, so i figured i would quit all the apps and restart my mbp to free up all the ram, well when i restarted my mbp the screen was black, and nothing was happening, but i noticed the white light on the latch was a soldid white, so i restarted the mac again and this time i pressed the option key and it brought me to a screen where i can choose what i want to do, so i clicked on my macintosh HD icon, and it booted my mac and i was able to use it.
so i was using it and i had to shut it down and pack it up to go home (from work)
and when i got home, and went to boot up my mac, it did the same thing, but this time i cannot get to the screen that i mentioned.
i dunno what to do now. i'm worried that it is damaged and will need repairs, but i cannot afford to pay for the repairs, and i need all my data that is on the hard drive, it has all my itunes, and iphoto libraries
please help! thanks
