I have had this laptop for about a month and from day 1 it has turned off at random intervals, i don't tons of research and numerous check to identify the problem and have found no solutions. It is not caused by overheating and my bios are up to date. What happens is without warning the screen will go blank and all sound will shut off, the screen appears be on but shows blackness and the power button remains lit. The only way for it to work again is if i hold the power button and turn it off then back on. Please Help!
