The Lenovo ThinkPad P50 laptop with the components described on www.ubuntu.com/certification/hardware/201512-20418/ has been awarded the status of certified pre-install for Ubuntu.
The system is available in some regions with a special image of Ubuntu pre-installed by the manufacturer. It takes advantage of the hardware features for this system and may include additional software. You should check when buying the system whether this is an option.
Standard images of Ubuntu may not work at all on the system or may not work well, though Canonical and computer manufacturers will try to certify the system with future standard releases of Ubuntu.
