I’ve a hp dv7 laptop, my laptop getting a black screen problem from last few days. The keyboard lights are on and blink continuously. I don’t understand why this problem is happening in my laptop. Since I’ve brought this laptop I’ve never experienced this type of problem. I’ve called to hp service center they are charging 400$. now, I don’t understand how to solve this problem. Please tell me or give me some suggestion on this, thank you in advance.
