Abstract:
1. In an apparatus, a method of operation comprising: powering the apparatus from a backup power source, in response to the apparatus being in an AC absence condition; initiating, by an Operating System of the apparatus in response to the apparatus being in the AC absence condition, a suspend to memory process to place the apparatus in a suspended to memory state wherein an operational state of the apparatus is saved to volatile memory requiring a source of electrical power to sustain the suspended to memory state, and wherein no further activity occurs while the apparatus is in the suspended to memory state including suspension of all data transmissions; setting, by a BIOS of the apparatus upon the initiation of the suspend to memory process, a timer to initiate waking up of the apparatus after a period of time and to facilitate shutting off the backup power source; and canceling, by the BIOS, the timer as part of a resume process initiated in response to AC power being re-present at the apparatus.
