Lenevo Ideapad y510p is not so much good as expected. As per rumour about this product in the market it had not shown so much satisfactory performance.
One of the biggest issue is its battery backup which is quite bad. Another most important problem is that you cannot use it without cooling pad as it gets heated soon. So if any one have to use it then one should must have a cooling pad. I also used this laptop but this had disappointed me a lot.
So I suggest you to think atleast twice or thrice before buying this one.
Thanks.
