# Lenovo Ideapad S10-3

## System Specification

- CPU: Intel Atom N450 (1.66 GHz, 512 MB L2 cache)
- Memory: 1 GB DDR2 SDRAM - can be expanded to a maximum of 2GB (one RAM slot)
- WiFi: Broadcom BCM4113
- Hard-Drive: 250 GB 2,5" SATA, 5400 RPM
- Optical Drive: None
- Integrated Graphics: Intel GMA 3150
- Sound: Intel HDA: Realtek ALC272

Note: Some newer models have an Intel Atom N455 (same spec as 450) and 1GB of DDR3 memory.

## Wireless

This laptop uses a Broadcom BCM4113 chipset for wireless networking. Some revisions have an Atheros AR9285 802.11b/g chipset.

### Free kernel driver for the Broadcom BCM4113 chipset

As of kernel version 2.6.37, there is now a Free driver in the kernel: brcmsmac. This driver should be loaded out of the box. It does however suffer from a resume issue in kernel 2.6.37 when the laptop resumes from suspend. The Wi-Fi does not come back up unless it is reloaded[broken link: invalid section].

### Non-free alternative driver for the Broadcom BCM4113 chipset

An alternative may be the 802.11 Linux STA driver, which can be installed from the AUR: broadcom-wlAUR

### Free kernel driver for the Atheros AR9285 802.11b/g chipset

The ath9k module is detected by udev and loaded out of the box.

Some users report issues with the `ath9k` driver and this particular chipset. In this case, use the ndiswrapper method. Also, add `!ath9k` and `ndiswrapper` to the `MODULES` array in `/etc/rc.conf`.

## Graphics

The Intel GMA 3150 requires the xf86-video-intel module. No xorg.conf file is required.

## Input

The keyboard and touchpad work more or less without problems using the xf86-input-keyboard and xf86-input-synaptics modules, respectively. Right- and left-clicking works, as well as vertical edge scrolling and right-click tapping. I have not managed to get two- and three-finger taps to work, nor two-finger scroll.

### Function keys

The function keys only work for some extent, e.g. the keys for turning off the LCD backlight works but not those for turning on and off Wi-Fi, touchpad, etc. To make the volume keys work, map "XF86AudioRaiseVolume" to "amixer set Master 5%+" and "XF86AudioLowerVolume" to "amixer set Master 5%-"

Notes: please use the second argument of the template to provide more detailed indications. (Discuss in Talk:Lenovo Ideapad S10-3#)

The brightness keys do not work and do not appear to be recognized by the system. To adjust brightness, see [1] and map `Super`+`Up` and `Super`+`Down` to the up and down scripts, respectively.

Create a file called something like "brighness_up" in a directory of your choice, e.g. `/home/your_user_name/scripts/brightness_up`

Paste the text below, and save the file.

    #!/bin/bash

    # these are the possible values:
    # 42 56 70 92 AF CC E5 FF
    # 30 40 50 60 70 80 90 100 %

    Current=`sudo setpci -s 00:02.0 F4.B`
    case $Current in
      42)
        sudo setpci -s 00:02.0 F4.B=56
      ;;
      56)
        sudo setpci -s 00:02.0 F4.B=70
      ;;
      70)
        sudo setpci -s 00:02.0 F4.B=92
      ;;
      92)
        sudo setpci -s 00:02.0 F4.B=af
      ;;
      af)
        sudo setpci -s 00:02.0 F4.B=cc
      ;;
      cc)
        sudo setpci -s 00:02.0 F4.B=e5
      ;;
      e5)
        sudo setpci -s 00:02.0 F4.B=ff
      ;;
    esac
    Current=`sudo setpci -s 00:02.0 F4.B`
    case $Current in
      42)
        notify-send "Brightness is at 30%"
      ;;
      56)
        notify-send "Brightness is at 40%"
      ;;
      70)
        notify-send "Brightness is at 50%"
      ;;
      92)
        notify-send "Brightness is at 60%"
      ;;
      af)
        notify-send "Brightness is at 70%"
      ;;
      cc)
        notify-send "Brightness is at 80%"
      ;;
      e5)
        notify-send "Brightness is at 90%"
      ;;
      ff)
        notify-send "Brightness is at 100%"
      ;;
    esac

And make the file executable, e.g

    chmod u+x ~/scripts/brightness_up

For lowering the screen brightness, make a script containing this:

    #!/bin/bash

    # these are the possible values:
    # 42 56 70 92 AF CC E5 FF
    # 30 40 50 60 70 80 90 100 %

    Current=`sudo setpci -s 00:02.0 F4.B`
    case $Current in
      ff)
        sudo setpci -s 00:02.0 F4.B=e5
      ;;
      e5)
        sudo setpci -s 00:02.0 F4.B=cc
      ;;
      cc)
        sudo setpci -s 00:02.0 F4.B=af
      ;;
      af)
        sudo setpci -s 00:02.0 F4.B=92
      ;;
      92)
        sudo setpci -s 00:02.0 F4.B=70
      ;;
      70)
        sudo setpci -s 00:02.0 F4.B=56
      ;;
      56)
        sudo setpci -s 00:02.0 F4.B=42
      ;;
    esac
    Current=`sudo setpci -s 00:02.0 F4.B`
    case $Current in
      42)
        notify-send "Brightness is at 30%"
      ;;
      56)
        notify-send "Brightness is at 40%"
      ;;
      70)
        notify-send "Brightness is at 50%"
      ;;
      92)
        notify-send "Brightness is at 60%"
      ;;
      af)
        notify-send "Brightness is at 70%"
      ;;
      cc)
        notify-send "Brightness is at 80%"
      ;;
      e5)
        notify-send "Brightness is at 90%"
      ;;
      ff)
        notify-send "Brightness is at 100%"
      ;;
    esac

Note: With Kernel 3.10.10-1 the function keys, including Wifi, touchpad, volume, and brightness, work out of the box
