However, ideapad-laptop.c sets max_brightness to 1, which means that the brightness is either off (0) or on (1). This means that I'm unable to select the high intensity brightness from ACPI like I could on a ThinkPad (I don't= own one, but thinkpad_acpi.c sets max_brightness to 2, so I guess that it doesn= 't have that problem). Still, I don't know if this feature is present on all IdeaPad laptops. I couldn't find any documentation on this (there is an article on Lenovo's support, but it only refers to ThinkPads*). Even the user manual of my lapt= op doesn't mention this (it only says that it has keyboard backlight, not that= it has three levels). Finally, I never tested Windows, so I don't know if Leno= vo Vantage provides any more settings. Also, small note: right now, if the keyboard brightness is at high intensity (with Fn+space, since there is no other way to do it), then is set to 0 usi= ng ACPI (and *not* with Fn+space), then set to 1 again with ACPI (still *not* = with Fn+space), the result is that the keyboard backlight will turn on with high intensity (and the next Fn+space will turn it off) instead of low. *https://support.lenovo.com/us/en/solutions/ht104451-how-to-turn-onoff-the-= keyboard-light-backlit-on-your-laptop-thinkpad --=20 You may reply to this email to add a comment.
