Installing OpenSUSE 13.1 on a ThinkPad T430s
Lenovo Thinkpad T430s 2356-LPG, BIOS G7ET90WW (2.50), ECP G7HT36WW (1.12)
This installation instruction describes these parts that do not or do not completely work after my OpenSUSE 13.1 DVD installation using KDE 4 as window manager.
Using the default BIOS settings, the Switchable Graphics with Intel HD Graphics and NVIDIA Optimus may cause high power consumption. Thus, if you do not need the NVIDIA Optimus graphics, change the BIOS settings from Switchable to Internal graphics before installation. Please read Switchable Graphics for the pros and cons. Note that I did not test the NVIDIA Optimus graphics.
LCD Brightness Buttons
The LCD brightness buttons stopped working because of a change in the 3.7 kernel. Adding
acpi_osi=\"!Windows 2012\" as a kernel boot parameter using YaST reverts to the old kernel behavior. However, there is no on-screen display feedback in KDE.
Suspend to RAM works out of the box. Unfortunately, the ThinkPad often reboots instead of shutting down. Installing the Laptop-mode-tools might help. But thereby SATA Link Power Management will be activated by default and the Intel SSD 520 with 180 GB and 240 GB could time out on heavy I/O load. There is a "beta" firmware update (LB3i) from Lenovo, but yet only for windows. Without the update, you have to set
INTEL_SATA_POWER="0" in /etc/laptop-mode/conf.d/intel-sata-powermgmt.conf.
However, there seems to be no need to install Laptop-mode-tools but to only set the PCI power management of the Ethernet controller
