## Configuration

### ClickPad

Works out of the box.

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 key lock can be switched with Fn + Esc.

### Backlight

Backlight control in GNOME with multimedia keys (Fn + F[5/6]) works out of the box. To configure brigthness level on startup see Backlight#Udev rule.

### Audio

Out of box 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

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 into Alt_L

Lenovo Forums topic

Issue can be meet on notebook with BIOS older than v2.16. Problem can be solved with BIOS update up to v2.16 or newer. 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. Always, do it at your own risk!

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

1) Download firmware from official support page:

BIOS v2.16:

    wget http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/j9uj16wd.iso

BIOS v2.18:

    wget http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/j9uj18wd.iso

Newest version can be found at E440 Downloads

2) Install the geteltoritoAUR utility.

3) Convert ISO image (change 'XX' to match the filename of downloaded .iso):

    geteltorito.pl -o bios.img j9ujXXwd.iso

4) Use USB stick to write image to. Suppose, you stick is /dev/sdb. Warning: all information on USB stick will be lost!

4.1) Unmount all /dev/sdb partitions:

    sudo umount /dev/sdbX (where 'X' is a partition of 'sdb')

4.2) Write image:

    sudo dd if=bios.img of=/dev/sdb bs=1M

5) Reboot you PC and boot from your USB stick.

6) FOLLOW ALL INSTRUCTIONS written in the update utility!
