I use this product since last one year. I bought this product from hp official store.
it is integrated with intel i5 processor, 4 GB ddr3 ram and 2 GB internal intel graphics.
It comes with windows 8.1 operation system. now I upgrade it in windows 10 .
It is the best performance PC . I do not found any performance issue and any computer esseseries issue. Battery backup is also good . it gives backup upto 4 hr in initial 4 to 6 month but it reduce to 1 to 2 hr after six month.
It is very good laptop in rs 42000 price range.
