This. I went to install Linux on a brand new $3k ThinkPad, to do this you had to disable dedicated Nvidia graphics during the install. Doing this on the the included bios bricked the machine and it spent two months getting the motherboard replaced at OfficeMax (lenovo had a partnership with them at the time). It took me another few weeks to get them to swap it for a new one because I didn't pay for a refurbished machine.
