This is one of the products from the Lenovo S-series, which is different from the IdeaPad S-Series.

## BIOS

The BIOS and the boot menu can be accessed by using the alternative power button, which is a small circular one on the left side near by the main power button.

## Wireless

Works after installing the proprietary driver module broadcom-wl or broadcom-wl-dkms, which supports Broadcom BCM43142. See the detailed Broadcom wireless page for further information.

## Graphics

See Intel graphics and xrandr.

## Backlight

Use one of the backlight utilities (tested with light) to adjust the backlight and control it with keyboard shortcuts by the method of your choice.

With kernel 4.0.x backlight can still be changed, but the keys for increasing or decreasing backlight brightness do not work anymore.

## Audio

Install alsa-utils. See ALSA for detailed information. To turn on the internal microphone, start `alsamixer` and increase the volume.

## SD Card Reader

This requires the `rtsx_usb` module [1]. Load the module and blacklist `sdhci`, `sdhci_acpi` and `sdhci_pci`, or install lenovo-s20-30AUR, then regenerate the initramfs.

## Changing fan mode

The fan mode can be changed with `echo 'X'>/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/fan_mode` provided by the ideapad-laptop kernel module, where X defines the fan cooling mode, i.e X can be one of the following possibilities:

- 1 = interval cooling
- 2 = regulate fan speed depending on temperature (default, but shows 133 or 5 by inspecting with `cat`)

In fan cooling mode 2, the fan starts, if the CPU temperature reaches 35°C and stops after the temperature is lower than 31°C.
