I bought this laptop in dec 2013 and till date I havent faced any issued with its working. It doesnt heat up, cooling fan doesnt feel too hot. The only issue with this laptop is that its a bit delicate. I used to use it on my lap until one day it fell and one of its back casing started coming off. I was under warranty, so called customer care.
They said this they cant send an engineer for on-site warranty as I didnt had ADP- accidental damage protection. How was I supposed to know what all kind of warranties you have for what parts. So then they said I had to go to my nearest service centre. I went there and the engineer there said he cant do anything. I said I am even ready to pay money, and requested him to ask for part. But he plainly refused and called service centre. Every time the lady said my laptop wasnt under ADP. I mean if I get it repaired from outside that would void the warranty, and they werent ready to guide me. I really didnt had good experience. So if you are one rough handler of laptop dont even think of buying this.
Also this laptop has nvidia 720m graphic card pf 2gb but still game lags and frames are lost. Rendering isnt good at all.
