Reason: Does not contain a hardware and function key table (Discuss in Talk:Lenovo Yoga 14s 2021#)

This page is for the Lenovo Yoga 14s 2021 (ITL) laptop equipped with Intel Core i5-1135G7, delivered starting from 2020-11-01 (China).

Special issues

Most things will work out-of-the-box, or just follow the normal set-up method. However, there are some issues you may want to solve before or during installation.

Keyboard not functioning properly

The keyboard may not function correctly, esp. normal input will not work. The behaviour includes: 1. keyboard light not switchable; 2. only some functional hotkeys are functioning. The issue may disappear after some time (varies from a few seconds to tens of minutes), or maybe not.

One way to workaround this is to add a kernel parameter during booting:

i8042.dumbkbd
Note: The light for the capslock key will not work with this method, though capslock is functioning as expected.

Screen flickering

This is due to Panel Self Refresh (a power saving feature of Intel iGPUs). See Intel graphics#Screen flickering for more information.

The current recommend way is to disable it, by adding with this extra kernel parameter:

i915.enable_psr=0

WiFi interface missing

The WiFi interface is missing sometimes after rebooting from Windows, but rfkill can still discover it.

It is known that after powering-off and booting again, this will be corrected.

Audio not working

This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.

Touch screen and pen not working

Update kernel to version >= 5.10.15
