Processor Intel Core i5 3rd Gen. Battery backup 4 hours plus. 2.40GHz laptop, everything is 100% okay, you can take it. It was sent from Japan/USA. Brother, I have been using it myself for 10/11 months, there is no problem at all. Everything runs very smoothly and fast, and you can do any kind of work very quickly. I am selling it now because I am buying a new one.
