Lenovo ThinkPad T450s

Installation
It is a good idea to update to the latest BIOS available, check the official page.

The installation procedure from a Gentoo installation media works perfectly as described in the Handbook.

Make sure to boot in UEFI mode (BIOS, Startup, UEFI/Legacy Boot must be set to [UEFI Only]) and follow the UEFI variants in the guide. Genkernel should generate a working kernel with pretty much everything working out of the box.

To customize the kernel, the section below describes the needed modules.

CPU
It is recommended to enable the microcode update support as explained in Intel microcode.

Kernel modules
These sections contain only the specific portion needed to enable the device. Most of the drivers can be compiled as modules or built directly into the kernel, it is up to the reader to choose the preferred way of compilation.

Hotkeys
If you have a recent BIOS installed all the Fn keys should work out of the box.

Bear in mind there's a BIOS option to alternate between standard F1-F12 functions and media functions: BIOS, Config, Keyboard/Mouse, F1-F12 as Primary Function.
