## Installation

See [Category:Getting and installing Arch](/index.php/Category:Getting_and_installing_Arch "Category:Getting and installing Arch")

## Hardware

### Audio

There are two options to get audio working: [ALSA](/index.php/ALSA "ALSA") and [PulseAudio](/index.php/PulseAudio "PulseAudio"). With ALSA the sound works well, both headphone jacks work and volume can be set independently. With Pulse Audio you will generally get better quality and louder sound.

### Video

The notebook comes with the [Intel HD 4000](https://en.wikipedia.org/wiki/Intel_HD_and_Iris_Graphics "wikipedia:Intel HD and Iris Graphics") GPU, which uses the [xf86-video-intel](https://www.archlinux.org/packages/?name=xf86-video-intel) driver. See: [Intel](/index.php/Intel "Intel") for details.

### Keyboard

Keyboard worked out of the box.

### Touchpad

Touchpad worked out of the box. To enable scroll and more, install [xf86-input-synaptics](https://www.archlinux.org/packages/?name=xf86-input-synaptics). With the default configuration file it will work well, but if you want to fine tune the behavior.

See: [Touchpad Synaptics](/index.php/Touchpad_Synaptics "Touchpad Synaptics").

### Wireless

This laptop comes Broadcom Corporation BCM43142 wireless card, which requires [broadcom-wl-dkms](https://www.archlinux.org/packages/?name=broadcom-wl-dkms)

See: [Wireless network configuration](/index.php/Wireless_network_configuration "Wireless network configuration").

#### Toggle between HDMI/Monitor

See [xrandr](/index.php/Xrandr "Xrandr").

### USB, SD card slot, ethernet, VGA, HDMI, webcam

All work out of the box.
