I bought this laptop in October 2015 and I was so excited about it but after using 8 months some of its button stopped working. I went to the service center and got my laptop repaired. After 5 months its cooling fan stopped working since my laptop was out of warranty period so I had to paid Rs.5000 to get my laptop repaired. It worked fro 2 months but after that the cooling fan became too much noisy, it produces sounds more than my ceiling fan also the battery of my laptop is dead now. I have to keep the laptop charger plugged in while I use. so in one and half year my laptop became scrap. Now its so called Dolby advanced audio also stopped working. I have to use my earphone everytime when I watch or listen some songs or movies. Its processor became slow when I open autocad and Google chrome at same the laptop starts hanging so more that I have to switch off my laptop. So I would say that this is not a good laptop, if you want to buy then go for Dell laptops.
