My friends each have a laptop (The same band) Well, a year ago one laptop went out. They would turn it on but the screen would be entirely black, the fans would stop after a few seconds and then the laptop would restart itself. After a while of trying to take the batery out and charger (Holding the pwer down) it wouldn't work but occasionally tapping the back would snap it on. Now it's back to black screen only.
Laptop two: This one would be fine but recently if left alone for an hour the laptop would be stuck on a black screen (Sleep or something I don't know they just walked away from it) They moved the mouse with no luck of turning it on. FInally they pressed the power button bu when it turned on it would flicker on for a second then turn off. Eventually it would be like laptop one (Black screen, no fans, restart itself) BUt this one does tend to snap on faster. Sometimes it they just restart the laptop it will boot up only a black screen then restart.
