Hii guys, I am used Lenovo ThinkPadX240 Laptop. I am not agree with this laptop features.I was purchased it about 2 years.In starting it gave a good performance.But when I started heavy use it can not work properly.mainly problem is battery, it is so bad because battery backup is just 1 hours now.When I contact to the lenevo care center, he tell me that your laptop will be exchange in about one week.But he did not gave me my laptop even 3 months, then I reported again lenovo center and this time he only repaired my laptop on the place of exchanging
