About ThinkPad S440

The Lenovo Thinkpad S440 was sold with optional touchscreen and optional ATI graphic card in addition to a standard intel graphic card. This entry is based on a non-touch model with the standard intel graphic card only.

Lenovo stopped selling the Lenovo ThinkPad S440 model [1]

BIOS

The Lenovo Thinkpad S440 has BIOS settings you probably want to adapt when deploying Linux on it. Download the user manual (Third Edition, published Jan. 2015) and have it at hand to understand the settings and their various option values. In the manual, go to Using the ThinkPad Setup program where a table of BIOS options can be found. BIOS settings which might be required for a successful install and can be found in the table below:

Menu item Submenu item Selection Explainations
Intel Smart Connect Disabled This function is not documented in the manual! Intel Smart Connect periodically fetches mail, social network messages and runs cloud synchronization while the computer is in standby. There are reports that this function leads to unwanted wake-up from power-safe modes.
USB USB UEFI BIOS Support Enabled (default) Keep on "Enable" if you plan to install Gentoo from USB stick.
Virtualization Intel(R) Virtualization Technology Disabled (default) Enable this if you want to run virual machines.
Virtualization Intel VT-d Feature Disabled (default) Enable this if you want to run virual machines (and utilize I/O virtualization).
Anti-Theft Intel AT Module Activation Disabled Intel® Anti-Theft Service will be terminated by the end of January 2015.
Anti-Theft Computrace Disabled Computrace is an optional monitoring service from Absolute Software.
Secure Boot Secure Boot Disabled (default) Required to boot "unauthorized operating systems" (a.k.a. Linux)
UEFI/Legacy Boot UEFI Only Use this setting to make 100% sure UEFI is used to avoid future confusion.
UEFI/Legacy Boot CSM Support No Prevents booting from MBR-partitioned disks because its successor, the GUID Partition Table (GPT) should be used. If you have trouble booting the installation medium temporarily set this to Yes.
Boot Mode Diagnostics Verbose boot process.

Leaving Microsoft Windows Installed

Lenovo's ThinkPad S440 comes with M$ Windows (8.1 or 7) pre-installed. I recommend to keep M$ Windows installed because

  • firmware or BIOS updates usually require M$ Windows (on their download site they offer Linux based tools too, so there is hope)
  • it comes in handy for troubleshooting sometimes
  • no M$ Windows install medium comes with the laptop. Therefore, reinstalling Windows is tiresome.

Lenovo's official download website for ThinkPad S440 is here.

If Gentoo was installed in dual-boot configuration with M$ the partition table should look similar(!) to this. Comments (marked by #) were added manually by me.

Kernel Configuration

Wireless LAN

In case you followed Wifi, it is sufficient to enable MVM Firmare support only. MVM supports Intel 7260 (which is built into this model) and 3160 devices, while DVM Firmware support supports all other Intel devices.

KERNEL 
    Device Drivers  --->
    [*] Network device support  --->
        [*] Wireless LAN  --->
            <M>   Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi)
                < >     Intel Wireless WiFi DVM Firmware support
                <M>     Intel Wireless WiFi MVM Firmware support

MMC/SD Card Reader

In order to use the MMC/SD card reader (the slot is on the left hand side of the notebook) you need to enable the respective drivers in the kernel config.

KERNEL 
    Device Drivers  --->
    <*> MMC/SD/SDIO card support  --->
        <*> MMC block device driver
        <M> Realtek PCI-E SD/MMC Card Interface Driver

Required packages

Sound

It may be that sound does not work out of the box. This is caused by the order in which the kernel modules are loaded and the fact that there is a HDMI and PCH sound card in the laptop.

First, test if the PCH sound card is functional. Get a list of all PCM devices

root linux #aplay -L
null
    Discard all samples (playback) or generate zero samples (capture)
default:CARD=PCH
    HDA Intel PCH, ID 510f Analog
    Default Audio Device
sysdefault:CARD=PCH
    HDA Intel PCH, ID 510f Analog
    Default Audio Device
front:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    Front speakers
surround21:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    2.1 Surround output to Front and Subwoofer speakers
surround40:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    4.0 Surround output to Front and Rear speakers
surround41:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    4.1 Surround output to Front, Rear and Subwoofer speakers
surround50:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    5.0 Surround output to Front, Center and Rear speakers
surround51:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    5.1 Surround output to Front, Center, Rear and Subwoofer speakers
surround71:CARD=PCH,DEV=0
    HDA Intel PCH, ID 510f Analog
    7.1 Surround output to Front, Center, Side, Rear and Woofer speakers
hdmi:CARD=HDMI,DEV=0
    HDA Intel HDMI, HDMI 0
    HDMI Audio Output
hdmi:CARD=HDMI,DEV=1
    HDA Intel HDMI, HDMI 1
    HDMI Audio Output

Next, test sound output (you should hear noise):

root #aplay -Ddefault:CARD=PCH /usr/share/sounds/alsa/Noise.wav
Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

Finally follow the advice given in ALSA#HTML5_does_not_play_in_firefox_browser and

FILE /etc/default/grubswapping sound card order
...
# change load order sound cards
GRUB_CMDLINE_LINUX_DEFAULT="snd-hda-intel.index=1,0"
...

Reconfigure and reinstall grub and reboot to make the change effective.
