Do not buy any products for Christmas were your return window is limited.  This product was not opened until Dec 25th and was minimally used until the semester started the 2nd week of January.  Now, 11 days past the return date, the battery is not working (does not last past 1 hour) and the computer keeps freeqing during exams and usage..... AMAZON CHAT WAS HORRIBLE..... no help at all. Will never buy anything electronic through amazon, nor will I buy anything other than books and then I may switch to Chegg..... This has been terrible......
