== Thinklight and backlit keyboard ==
Both of these features work as expected out of the box.

== Brightness ==
Brightness control works using the expected Fn + function keys, however only 6 levels are detected. To control up to 16 levels of brightness, you can add the {{bootparm|acpi_backlight|vendor}} kernel parameter to the boot options{{footnote|1}} :
# Edit the {{path|/etc/default/grub}} file:<BR/>{{cmduser|gksudo gedit /etc/default/grub}}
# Append {{bootparm|acpi_backlight|vendor}} to the default kernel parameters:<BR/>GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
# Update GRUB:<BR/>{{cmduser|sudo update-grub}}

Reboot to make the changes effective.

== Wireless ==
Wireless does not work with 100% free drivers out of the box. The internal half mini PCIe card can't be replaced by a compatible card as this system uses BIOS whitelisting. There isn't a modified BIOS available yet (as of Jan 15 2013).

As a workaround, an external USB adapter such as those sold by [http://libre.thinkpenguin.com ThinkPenguin] can be used.

== Fingerprint reader ==
The fingerprint reader does not work with 100% free drivers out of the box.

== Battery ==
Several optimizations are needed to maximize battery time. Most apply to any Gnu/Linux distributions, except for running Libre kernels. See [https://trisquel.info/en/wiki/optimizing-battery-time Optimizing battery time] on the Trisquel wiki.

When testing the newest Libre kernels as indicated on the Trisquel wiki, some functionality was lost (like wireless access and brightness controls)
