I was using this Lenovo G450 since 3 years and I have experienced that this laptop is quite good. In first year it performed well as described and all things were going alright. In second year it’s battery got died which is a major problem and I also hate this problem, Infact I didn’t replaced the battery and used it normally. It works good when on charging and worst without charging.
It charge lasts upto 15 minutes after death but before death of battery it gave about 3 hours of battery backup. And last in 3rd year I changed the windows from XP to Windows 7 and it is working like a charm but battery problem is also there. But its performance increased and quality also. But I will not recommend anyone to buy this laptop at this price as many more good laptops are available at this price segment.
Thanks.
