ClickPad

The only tweak you may want is to resize active area. With default config, you can cosily use as pointer only top 1/3 of ClickPad. See Touchpad Synaptics#Buttonless touchpads (aka ClickPads) for instructions.

Keyboard

Fn and Ctrl keys can be swapped in BIOS.

Fn lock can be switched with Fn+Esc.

Backlight

Backlight control works with multimedia keys (Fn+F5/Fn+F6). To configure brightness level on startup see Backlight#Udev rule.

Audio

Default configuration could point to non-existent device because numbering of HDMI devices does not start with 0. Suggested solution is to set PCH device to default by placing a configuration file into /etc/modprobe.d. The following thread contains alternative solutions and detailed instructions: Fixing ALSA device selection.

Troubleshooting

Freezing on resume

Reason: This recommends using the LTS kernel, but this was added with Special:Diff/377658 in 2015: it's certainly not applicable today. (Discuss in Talk:Lenovo ThinkPad Edge E440)

When system is being suspended, it could freeze on wake up. Most likely, this bug occurs with BIOS v2.16.

Simple solution is to disable USB 3.0 in BIOS. Better solution is to update BIOS to v2.18. Instructions on update can be found below.

Even with new BIOS version (2.18), hibernation still does not fully work. Use the LTS kernel to fix issues.

With Fn and Ctrl_L keys swapped, Ctrl_L+s hotkey is mapped to Alt_L

Lenovo Forums topic

Issue is present on notebooks with BIOS versions older than v2.16. Problem can be solved with a BIOS update up to v2.16 or newer. See the BIOS v2.16 update changelog.

Blinking power LED after resume from suspend

This is not a real problem, but can be annoying and has a very simple solution: 

# echo "0 on" > /proc/acpi/ibm/led

For automation, create a script depending on the used power management tool.

BIOS Update

Steps below were tested by contributors of this page and work perfectly. However, do the following procedure at your own risk!

To update the BIOS from a USB drive, follow these steps (alternatively, you can download the ISO, burn it to a CD, and then boot from the CD):

  1. Download the latest firmware from the official E440 Downloads page (search for "BIOS Update (Bootable CD) for Windows").
  2. Install the geteltoritoAUR utility.
  3. Convert ISO image: 
    $ geteltorito.pl -o bios.img j9ujXXwd.iso
  4. Write the image to the USB drive. Suppose, your drive is /dev/sdb. Warning: all information on USB stick will be lost!
    1. Unmount all partitions associated to the drive (perform for every existing 'X'): 
      # umount /dev/sdbX
    2. Write image: 
      # dd if=bios.img of=/dev/sdb bs=1M
  5. Reboot you PC and boot from your USB drive.
  6. FOLLOW ALL INSTRUCTIONS written in the update utility!
