Abstract
A computing device includes: a battery compartment configured to removably receive a battery; a backup power source; a computing subsystem configured to receive power from a selectable one of the battery and the backup power source; a backup power regulator configured to supply backup power from the backup power source; and a power control subsystem configured, in response to detecting removal of the battery from the battery compartment, to: control the backup power regulator to increase an output voltage level of the backup power; and supply power to the computing subsystem from the backup power regulator.
Claims18
A computing device, comprising:
- a battery compartment configured to removably receive a battery;
- a backup power source;
- a computing subsystem configured to receive power from a selectable one of the battery and the backup power source;
- a backup power regulator configured to supply backup power from the backup power source;
- and
- a power control subsystem configured, in response to detecting removal of the battery from the battery compartment, to:
- control the backup power regulator to increase an output voltage level of the backup power;
- and
- supply power to the computing subsystem from the backup power regulator.
A method, comprising:
- supplying power to a computing subsystem of a computing device from a removable battery received in a battery compartment of the computing device;
- controlling a backup power regulator of the computing device to supply backup power from a backup power source at a nominal output voltage level;
- detecting removal of the battery from the battery compartment;
- in response to detecting removal of the battery, controlling the backup power regulator to increase the output voltage level of the backup power above the nominal output voltage level;
- and
- supplying power to the computing subsystem from the backup power regulator.
