Laptop is the librem 13 (not helpful, I know). Graphics chipset is broadwell. Cpu is i5-5200. Haven't been able to get the motherboard model. However, I have model numbers from the bios. Bios is American Megatrends. BIOS Version is 108. EC version is 2.1u. M/B version is D. On March 12, 2016 11:45:00 PM EST, Adrian Chadd <adrian.chadd@gmail.com> wrote: >Hi, > >Which laptop?

Once that gets updated then yeah, the resume backlight will work. :-P -a
