Abstract: An example computing device includes a battery to power the computing device, a first operating system (OS), a second OS, and a hypervisor. The hypervisor is to: monitor a parameter of the first OS related to power to be drawn by the computing device for the first OS to enter a hibernate state; monitor a parameter of the second OS related to power to be drawn by the computing device for the second OS to enter the hibernate state; set a first modified remaining battery capacity of the first OS based on an actual remaining battery capacity of the battery and the parameter of the first OS; and set a second modified remaining battery capacity of the second OS based on the actual remaining battery capacity and the parameter of the second OS.

Abstract: As part of starting a system including a system-on-a-chip (SoC) device from a mode in which power is removed from the system, the SoC device determines, based on the metadata, whether to resume the system to a prior system state. In response to the metadata indicating that the system is to be resumed to the prior system state, the system is resumed to the prior system state using system state information stored in the on-chip non-volatile memory.
