If any body is buying this laptop to work in Internet then its better not to use this laptop. Because I saw critical wifi device in this laptop. I check and console with technician also but the problem couldnt be dedected. This unit has a know issue with poor wifi, completely known by Dell, yet they keep on selling it. I acquired two or three months prior, reported the prob instantly, tech turned out to change the card, yet as you’ll check whether you investigate this further, the prob can’t be altered.
Without that problem I fell good in performance in this.
