Tested and Verified on Fedora 24
Information in this section has been tested and verified using Fedora 24.
In the BIOS (F1 to enter during boot), be sure to disable secure boot.
Security > Secure Boot > Secure Boot = Disabled
Also, if your planning to run any kind of virtual machines, make sure you enable the CPU virtualization support.
Security > Virtualization > Intel (R) Virtualization Technology = Enabled
And while your in the BIOS setup you may also want to immediately change the default Function key behaviour. On this ThinkPad by default the function keys will not work as one would expect. When pressing F1 you do not get F1, but you get Mute. To get F1 you need to press Fn-F1 or you first need to enable the FnLk (Fn-ESC). To reverse this behaviour back to how to should be, change the setting in the BIOS.
Config > Keyboard/Mouse > F1-F12 as Primary Function = Enabled
By default, the installation will hang immediately after the bootloader with a black screen. It is necessary to edit the boot options and add "intel_pstate=disable" to the end of the line of options.
After this, installation is straight forward; you can follow the generic Fedora install instructions.
As root, edit /etc/default/grub and adding the option
intel_pstate=disable which will prevent a hang at boot. After adding this, update the grub configs with the following (assuming default uEFI setup);
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
There is a work around for this BIOS bug in the 4.6 kernel, which is not available for Fedora 24 at this point.
X Server - Intel HD Graphics
Works out of the box.
If you have the HiDPI display option, it brings with it a whole lot of issues. Most of them are covered here; ArchLinux HiDPI.
Basically everything is quite large as it tries to scale everything 2x when a HiDPI display is detected. In fact a bit too large to my liking. On the archlinux website there are some hints and tips on how to scale things down a bit again, but it is really a hack and far from ideal.
Also having a HiDPI primary display causes everything on external non-HiDPI displays to appear huge as they will receive the same scaling factor. This is a limitation of the X11 windowing system. The long term solution would be to switch to a Wayland desktop which is able to handle multiple displays with various DPI settings.
