I have installed windows 8.1 and converted it into fresh condition, now everything is
perfect and working no defect or problem except battery strength is very low now, maybe
5 to 10 minutes capacity so you need to use always in plugged in mode. I am selling it
because I need a better laptop for playing games likes GTA V or so.
