Your keyboard will let you know when it is running low. From 100% to 11% your LED will be green. From 10% and below, the LED will be red. You can continue typing for more than 500 hours without backlighting in a low battery.
To charge your keyboard plug the USB-C cable at the top right corner. You can continue typing while it is charging.
NOTE: The cable is for charging purposes only.
Your keyboard has an embedded ambient light sensor that reads and adapts the level of backlighting accordingly.
|Vertical light reading under specific conditions||Backlight level|
|Low light - under 100 lux||L2 - 25%|
|Mid light - between 100 and 200 lux||L4 - 50%|
|High light - over 200 lux||L0 - no backlight*
Backlight is turned OFF.
Total backlight levels: eight.
You can change the backlight levels at any time. There are two exceptions — the backlight cannot be turned ON when:
- the room brightness is high
- when keyboard battery is low
Change backlighting effect
MX Mechanical has six different backlighting effects. By default the behavior is static. To swap, you can press Fn + the lightbulb on your keyboard or change it using the Logi Options+ software.
Install the software Logitech Options+ to get the most out of your keyboard.
You can find more information here.
Backlight level notifications
Change the backlight level and you’ll know in real time what level you have.
There are two factors that will disable backlighting:
When your keyboard has only 10% of battery left, when you try to enable backlighting, this message will appear. If you want backlight back, plug your keyboard to charge.
When the environment around you is too bright, your keyboard will automatically disable backlighting to avoid using it when not needed. This will also allow you to use it longer with backlight in low light conditions. You will see this notification when you try to turn backlighting ON.
When your keyboard reaches 10% of battery left, backlighting turns OFF and you get a battery notification on screen.
When you do Fn + Esc you swap between Media keys and F-Keys.
We’ve added a little notification so you know when you swapped.
NOTE: By default, the keyboard has direct access to Media Keys.
You can work on multiple computers with your MX Mechanical. With a Flow-enabled Logitech mouse, such as MX Master 3S, you can work and type on multiple computers with the same mouse and keyboard using Logitech Flow technology.
You can use the mouse cursor to move from one computer to the next. MX Mechanical will follow the mouse and switch computers at the same time. You can even copy and paste between computers. You will need to install Logitech Options+ software on both computers and follow these instructions.
