Example Input: Hello everyone! I bought this computer and unfortunately I hadn't any luck. In just one week the laptop performance changed completly, working worst than another seven years old laptop that I have. Here in Brazil I let the computer in an authorized service, there are more than one month and Acer can't solve my problem. I'm without the laptop, without any news about what is gonna happen and I'm deeply disapointed with this brand. I don't recommend.
