## System Configuration

### Fingerprint scanner

TODO: check.

### 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.
