I have a Dell inspiron 15 3000. The thing is that I'm unable to start my laptop. I've tried to take out it's battery and also tried to start it with it's adapter. It's been 6 months that I have bought it. I'm concerned that this happened just in the period of 6 months. It's just about last night that rather than shutting it down I just pressed the power button directly. But I have been doing that periously 2 to 3 times, but this didn't happen before. Need Help!
