摘要： A power management method and device for a multi-operating system (OS) electronic apparatus can employ a host OS including first power attribute files, each including a power pack name and a power attribute name. A guest OS includes second power attribute files, each including a pack name code and an attribute name code corresponding respectively to a power pack name and a power attribute name in each first power attribute file. When any second power attribute file is called, a pack name code and an attribute name code corresponding thereto are decoded in the guest OS to obtain a called power pack name and a called power attribute name, which are then sent to the host OS. The host OS then provides the corresponding first power attribute file to the guest OS. The invalidity risk of any power attribute file in the multi-OS electronic apparatus can therefore be reduced.
