Hi, I have an HP pavilion entertainment PC (hp pavilion dv4). Well my lap top needed and update one day and i pressed okay but the problem is that once it shutdown it would not even turn on. I mean the laptop would turn on but not the screen I tried doing the power option meaning i held the power button for 30 secs then 60 secs after it didn't work. i removed the battery and all that. I cant even do safe mode start up because the screen is black. no even the logo windows shows up. I connected it to a monitor but nothing. The caps and the scroll button turn on and off after a few secs then again. I have a huge 15 page paper due and it's in here, please tel me someone can help. I'm freaking out!
