I'm collecting notes related to this laptop, mostly regarding Linux support. I am running Gentoo Linux, but the information should be distribution agnostic.
Works out of the box
Works with extra effort
Does not work at all
BIOS update CD/ISO-image|
BIOS-Update for Windows
This laptop has no CD drive. If you have a dual boot system with Windows you can update there. If you have an external CD use that. Writing the BIOS update ISO to a USB stick is possible with these instructions and the geteltorito perl script.
Please note that the BIOS update 1.17 fixes security vulnerabilities CVE-2014-4859 and CVE-2014-4860.
|Hard disk||Lenovo mentions problems with earlier firmware versions of the HD and has a firmware update tool (Windows only). smartctl -a /dev/sda can show you the firmware version. In my system the SSD is called MZNTD512HAGL-000L1 and the current firmware version is DXT24L0Q.|
|CPU CFLAGS||gcc option -march=corei7-avx optimizes for the CPU.|
Xorg synaptics driver 1.8 got
better support for the touchpad.|
The current driver uses a deprecated PS/2 interface, it'd be better to use the RMI4 interface however it seems this is not ready yet.
|GPU/Backlight||The xf86-video-intel driver is lately in really bad shape, so it
is recommended to use xf86-video-modesetting instead.|
However the modesetting driver does not support controlling the backlight yet. There's a perl script called ybacklight that uses an alternative sysfs interface and works with the modesetting driver. Alternatively there's cbacklight written in Python 3.
