Hi People reading this post,I've been having so many problems with the P640RE Def ||but in the last week or so random shutdowns while idle or gaming, I suspect it is motherboard 'cause when it shutdowns and I try to turn it back on it doesn't and have to wait some seconds also the charger needs to be replugged. On time varies for some reason. Sometimes it's 5 minutes or 8 hours?!!?!Google Fu is useless here!Thx,Abdullah
