Battery management
Your keyboard has up to three years of battery life.*
Battery sleep mode
Did you know that your keyboard goes into sleep mode after you stop using it for a few
minutes? This feature helps limit battery usage and eliminates the need to keep switching
your devices on and off. Your keyboard is up and running immediately once you begin using
it again.
How to check the battery level
Turn the keyboard off, and then on using the On/Off slider switch on the top edge of the keyboard.
Look at the battery LED on the top case. If the LED glows green for 10 seconds, the batteries are
good. If the LED blinks red, the battery level has dropped to 10%. (You still have a few weeks of
battery usage left.)
On/Off slider switch
* Battery life varies with usage and computing conditions. Heavy usage usually results in shorter
battery life.
