/// ## Smart Battery Table (SBST)
///
/// If the platform supports batteries as defined by the Smart Battery Specification 1.0 or 1.1, then an Smart Battery Table (SBST) is present.
/// This table indicates the energy level trip points that the platform requires for placing the system into the specified sleeping state
/// and the suggested energy levels for warning the user to transition the platform into a sleeping state.
///
/// Notice that while Smart Batteries can report either in current (mA/mAh) or in energy (mW/mWh),
/// OSPM must set them to operate in energy (mW/mWh) mode so that the energy levels specified in the SBST can be used.
///
/// OSPM uses these tables with the capabilities of the batteries to determine the different trip points.
