There are three ways to check your Slim Book Pro’s remaining battery power. First, you can open your iPad’s widgets and see it displayed as a percentage there. Second, you can download the mophie® Power app from your favorite app store. The mophie app will walk you through installation and how to use the app to check your battery life. Third, you can press fn + the battery key. This will cause the LED indicator to flash one of the following three ways:
- Three flashes = full battery life.
- Two flashes = approximately half battery.
- One flash = low battery. When your Rugged Book Pro reaches critical battery level, the LED will flash once every five minutes.
To help preserve battery life, your Slim Book Pro will enter sleep mode if left on and not used for several minutes; press any key to wake it. The Slim Book Pro’s battery has no memory and may be charged whenever you wish. For optimal battery life, turn your Slim Book Pro off when not in use for a prolonged time. The battery is not replaceable, so if your keyboard is not charging up and was purchased within the warranty timeframe, you can request a replacement by clicking here.
