I think Lenovo products are having lots of engineering issues and providing horrible customer support. I am having Lenovo ThinkPad T410s from past around a year. I noticed that FPS is getting drop to 2-4 when I am using couple of apps. I noticed that system of mine was started to overheat and getting shutdown automatically. I sent the same at service depot and they replaced fan and palm rest. After 15 again my laptop shutdown again. after couple of hours of checking, explaining and arguing with the customer representative he agreed that there was no fault of palm rest and took the device back. They again replaced plam rest as well as motherboard. After that there was no shutdown. As I connected headphone jack I got high pitch noise and static coming from the audio system. so again I sent my laptop to service center. So far I am having really worst experience with the Thinkpad and they had destroyed the brand by all mean.
