I was on my laptop (HP Pavilion dv7-1135nr) earlier today and the screen just went blank. I was plugged in and the battery was a full charge (or as full as it will get since it won't go past 85%), and the fan wasn't running really hard. Like I said, I was just surfing the web and the screen went blank. I restarted it a few times but that hasn't done anything. It did this one other time this week. I really need to get a few files off of it, please help!
