I don't know, but my Acer is next to worthless. Would not recommend this machine for you to purchase. Called Acer 6 days after purchasing & it was recommended that I reformat from their web-site. Slick way to accomplish this but not any better. Second call & some guy wanted to sell me a $500 policy to keep computer running for 5 years. Reformated 2 more times with no improvement. Also, my machine has McAfee protection and got a new Net Gear Router.
