As mentioned, the Slim Book features a powerful, rechargeable battery that lasts up to two years between charges. To check your Slim Book’s remaining battery power press the battery key. The LED indicator will flash one of three ways.
1. Three green flashes indicate 50% or more battery life remaining.
2. Three yellow flashes indicate between 25%-49% battery life remaining.
3. Three red flashes indicate less than 25% battery life remaining. When your Slim Book reaches critical battery level, the red light will flash once every five minutes.
To help preserve battery life, your Slim Book will enter sleep mode if left on and not used for several minutes. To awaken your Slim Book, press any key. The Slim Book’s battery has no memory and may be charged whenever you wish.
