Discrete GPU
This model uses PRIME for combining the integrated and the dedicated GPU. As the external graphic ports are wired to the discrete GPU, drivers for the discrete GPU need to be present in order to use them. However, no special X.org configuration should be necessary, as xrandr should detect the ports automatically. If not, follow the instructions in PRIME#Reverse PRIME.
Disabling discrete GPU via acpi
The built in GPU can be disable and re-enabled on the fly via acpi call. This can significantly reduce power consumption and increase battery live up to a factor of 5.
See Hybrid graphics#Using acpi_call, the specific ACPI call for this device is \_SB.PCI0.PEG0.PEGP._OFF.
Fan control
The default operation of fans is noisy, as they are basically at medium power all the time. The thinkfanAUR program can be used to create a quieter operation, while retaining reasonable temperatures.
Here is an example /etc/thinkfan.conf configuration:
/etc/thinkfan.conf

Enabling Turbo boost
By default, the CPU power governor does not allow CPU frequencies to reach turbo boost speeds. This can be fixed via, for instance, cpupower-guiAUR.
This can be changed by modifying the file /etc/cpupower_gui.conf:
/etc/cpupower_gui.conf
[Profile] #This setting was: profile = Balanced profile = Performance
Then start/enable cpupower-gui.service.
Firmware
This Device has fwupd support.
