@Reimundo: like in your case, many of my LEDs do not work in the UEFI mode. I ended up switching to the CSM where the samsung-laptop module is not blacklisted. Bluetooth and all LEDs on my laptop work just fine in the CSM. Until the samsung-laptop module is ported to the UEFI, our Samsung laptops are not very useful when booted via UEFI.
