Lenovo IdeaPad S400 Touch
Installation/Setup
When I first purchased the laptop it came preinstalled with Windows 8.1. In order to begin the Arch Linux installation I had to, in Windows 8, enable booting into the BIOS via the Advanced Settings tab under Settings. Once in the BIOS I had to disable Secure Mode, enable USB boot, and enable Legacy Boot. From here I was able to install Arch without any problems. I chose to completely remove Windows 8.1, but should you want to preserve this OS please refer to the Beginners' guide for more information.
Wireless
Wireless works out of the box however it is recommended that you install the broadcom wireless drivers as I have found the wireless speed can become throttled without them.
Post-Installation/Configuration
Touch Screen
Works out of the box however gestures are not supported, the touch interface essentially just acts as another way to left-click.
