Claim:
A method for starting up a mobile device having a battery, said method comprising: (a) examining a battery level of the battery; (b) determining whether the battery level is substantially depleted; (c) determining whether an external, power-limited power source is electrically coupled to the mobile device; (d) deferring start-up of the mobile device while charging the battery via power provided to the mobile device from the external, power-limited power source when said determining (b) determines that the battery level is substantially depleted and said determining (c) determines that the external, power-limited power source is electrically coupled to the mobile device; (d1) after a delay imposed by the charging during said deferring (d) of start-up of the mobile device, determining whether the battery level is at least adequate to assist the external, power-limited power source to at least achieve successful start-up of the mobile device; (d2) halting charging of the battery when the determining (d1) determines that the battery level is at least adequate to assist the external, power-limited power source to at least achieve successful start-up of the mobile device, wherein said battery level is less than fully charged; and (d3) starting-up of the mobile device using power from the battery and the power provided to the mobile device from the external, power limited power source.
