I believe the Lenovo is just a terrible hardware producer. I got a T410S when I started at my new company. It was brand new. 3 months later the screen had a 1" thick white line on the monitor. I treated the thing like royalty. A few months later the plastic casing started to crack despite the lack of obvious impacts. 6 months later, a fan error prevented it from booting. I bought a mac book air at the same time, and it's still looks/works like the day I bought it!
