Introduction

Lenovo Y520 is a thin-and-light 15.6" workstation/multimedia laptop from Lenovo's 2017 Lenovo Legion lineup.

There are three laptop models in Y520 series:


The Y520-15IKBM model has a DisplayPort mini connector, while the Y520-15IKBA and Y520-15IKBN models have a Memory card slot 4-in-1 Card Reader (SD, SDHC, SDXC, MMC).

Lenovo Y520 is a good laptop for installing Gentoo Linux. The laptop has a solid build, a good keyboard, and a nice 15" 1920x1080 Full HD LED Backlit Anti-glare IPS Display. It is possible to have both NMVe and an SSD or spinning hard disk.

Note
Although it is possible to have both NMVe and an SSD, this page describes the model with NMVe only.

.

After proper configuration, every part of the Lenovo Y520 is Linux friendly.

Installation

The installation is per the Gentoo AMD64 handbook.

Some specific configuration options are:

  • USB support, configuring xHCI, EHCI
  • Audio according to ALSA and optionally PulseAudio. Make sure to enable build Realtek HD-audio codec support.

Firmware

Microcode

Intel released microcode updates that fixes fault on processors. Install the officially published microcode package sys-firmware/intel-microcode. For more info see Intel microcode.
