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.

Suspend to ram

After upgrading BIOS to latest version, notebook hangs after resuming. See bug description here. Solution is to disable USB 3.0 in BIOS.

Keyboard

Fn and Ctrl keys can be swapped in BIOS.

Fn key lock can be switched with Fn + Esc.

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

Problem solved with 'j9uj16wd'(v2.16) BIOS update.

DO IT ON YOUR OWN RISK!

To update BIOS, follow these steps:

1) Download firmware from official support page:

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

2) Install geteltorito utility from AUR:

yaourt -S aur/geteltorito

3) Convert ISO image:

geteltorito.pl -o bios.img j9uj16wd.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 load from your USB stick.

6) Follow all instructions written in the update utility!

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.
