I've upgraded original BIOS to this version: Vendor: LENOVO Version: G1ETA1WW (2.61 ) Release Date: 12/03/2013 BIOS Revision: 2.61 Firmware Revision: 1.12 > Mariano, any chance you could try with a 3.16 kernel ? > Yes, I tried 3.16.1 and the bug IS present > Also can you please try adding: "video.use_native_backlight=0" the the > kernel commandline with 3.14.6?
