How can I lock the light effect? Miya February 07, 2023 03:59 Updated For the regular K series, please press the fn+L +light effect key for 6 seconds to lock it. Related articles If I turn off automatic sleep mode, do I have to turn off the keyboard (by switch) every time I turn off my PC? Should the keyboard be cleaned frequently with alcohol? When I have the backlight turned off, the keyboard still has a very dim light that is only visible in a pitch black environment, is that normal? Is there any way I can remap 'fn1' and 'fn2' on my K6? Does the K2 PBT Keycaps fit on the K8?
