Okay so a few months ago my windows 7 laptop started powering off without warning. It usually happens when I turn the computer on and it can't even make it past the login screen most of the time. Recently my problems with this have gotten much more severe. Now the laptop can't make it past the login at all unless it's in safe mode. I have replaced the battery and have also cleaned out the entire laptop of dust but none of it helps. I have even gone so far as to factory reset the whole thing and still my problems reappeared after a few days. Also one more thing I have noticed is that whenever I turn on the laptop the sleep mode light on the front is always on, even when everything works fine. I'm about to give up on this whole thing if it can't be fixed so any help would be appreciated, thanks.
