I had this laptop for about 2 weeks and everything was working well.  Then after about 2 weeks, I had trouble turning it on or off with the power button.  When it was in sleep mode, I couldn't wake it up.  After some research, I found that this model did have a history of similar problems  The only way I could get it to work was to push in the reset button.  It appears there was a problem with the power button.I returned the laptop to Amazon with no problem.
