Abstract
For one disclosed embodiment, power from a backup battery may be received by first circuitry. One or more other batteries different than the backup battery may be tested with the first circuitry. Second circuitry may be allowed to supply power from at least one of the one or more other batteries to at least one electronic component at startup based at least in part on the test having a first result. Startup of the at least one electronic component may be prevented based at least in part on the test having a second result. Other embodiments are also disclosed.
Claims30
An apparatus comprising:
- first circuitry to receive power from a backup battery, the first circuitry to test one or more other batteries different than the backup battery;
- and
- second circuitry to control supplying power from the one or more other batteries to at least one electronic component,
- the first circuitry to allow the second circuitry to supply power from at least one of the one or more other batteries to the at least one electronic component at startup based at least in part on the test having a first result, and
- the first circuitry to prevent startup of the at least one electronic component based at least in part on the test having a second result.
A method comprising:
- receiving power from a backup battery by first circuitry;
- testing with the first circuitry one or more other batteries different than the backup battery;
- allowing second circuitry to supply power from at least one of the one or more other batteries to at least one electronic component at startup based at least in part on the test having a first result;
- and
- preventing startup of the at least one electronic component based at least in part on the test having a second result.
An apparatus comprising:
- undervoltage detection circuitry to receive power from a backup battery, the undervoltage detection circuitry to identify whether a voltage of another battery different than the backup battery is less than a threshold;
- and
- direct current to direct current (DC-to-DC) converter circuitry to control supplying power from the other battery to at least one electronic component,
- the undervoltage detection circuitry to allow the DC-to-DC converter circuitry to supply power from the other battery to the at least one electronic component at startup if the voltage is greater than the threshold, and
- the undervoltage detection circuitry to prevent startup of the at least one electronic component if the voltage is less than the threshold.
A method comprising:
- receiving power from a backup battery by undervoltage detection circuitry;
- identifying with the undervoltage detection circuitry whether a voltage of another battery different than the backup battery is less than a threshold;
- allowing direct current to direct current (DC-to-DC) converter circuitry to supply power from the other battery to at least one electronic component at startup if the voltage is greater than the threshold;
- and
- preventing startup of the at least one electronic component if the voltage is less than the threshold.
