Hey, I have a HP 15.6 inch touchscreen laptop (not sure of the make). I've had it for almost 2 years and yesterday I left it to charge and when I came back to it (it was still supposed to be turned on) it kept making ghhhghhhhhghhhjjjjjj sound (I don't know how else to put it in words) and I couldn't get it to start up again so I tried to turn it on and get it to respond but it didn't and it kept making the sound. I then held down the off button in order to just get it to turn off in hope that it would be okay and then i immediately turned it on again and it did the same thing and I didn't know what to do so I shut it off again and left it and hoped that it would turn on and be okay later on. I turned it on today and the lights wouldn't even come on, I plugged in the charger but to no avail. It's gone and I'm not sure if it will work again. Help???? Is there anything I can do????
