I purchased Lenovo G50 few months back and I am totally dissatisfied with the performance of this laptop. It takes about 20 to 30 second to refresh a page if you will right click then it will take 10 to 20 seconds .I found this laptop very slow. I will suggest never buy this laptop because if you will buy this laptop your money is going to be wasted.
This laptop hangs very frequently and doesn’t give any good performance even while watching movies it get sometime hanged .I complaint about this to Lenovo service centre the a person from lenovo came and he updated my system but still the problem was same.
