INTELLIGENT BATTERY SYSTEM

摘要

An intelligent battery power system having a main battery and a swap battery including a battery presence detector for detecting whether the main battery is present and a power controller for operating the system in a suspend mode and applying power from the swap battery in a suspend mode when the battery presence detector detects that the main battery has been removed and for interrupting the power from the swap battery with power supplied from the main battery to operate the system in a resume mode when the battery presence detector detects that the main battery is present. The system prevents volatile data from being lost when the battery for a portable computer is removed or becomes detached for any reason.
