I claim: 1. A method of operating a machine for the treatment of sleep apnea comprising: providing a machine for the treatment of sleep apnea that operates on D.C. power, wherein the machine includes a motor and compressor that are operationally coupled with a mask for delivering pressurized air to a patient; providing a power supply system for providing D.C. power to the sleep apnea machine, wherein the power supply system includes: an A.C.-to-D.C. converter for receiving an A.C. power input and converting the A.C. power into a D.C. power output; a rechargeable battery operationally coupled with the D.C. power output of the A.C.-to-D.C. converter; and a D.C.-to-D.C. converter operationally coupled with the rechargeable battery and the D.C. power output of the A.C.-to-D.C. converter, wherein the D.C.-to-D.C. converter receives a D.C. voltage within a range having a minimum and a maximum and outputs a D.C. voltage at a fixed level for powering the machine for the treatment of sleep apnea; and activating an audible alarm sufficient to wake a sleeping patient when the rechargeable battery is nearly depleted and A.C. power to the A.C.-to-D.C. converter fails but not activating the audible alarm when the rechargeable battery is able to provide power sufficient to operate the machine for the treatment of sleep apnea. 2. The method of claim 1, further comprising the step of providing a power-failure indicator, wherein the power failure-indicator is operationally coupled with the A.C. power input and activates a visual indicator upon loss of A.C. power, wherein the visual indicator remains activated after restoration of A.C. power and is deactivated only by a manual reset and wherein the visual indicator does not wake a patient upon activation. 3. The method of claim 2, wherein the visual indicator comprises a LED. 4. The method of claim 1, wherein the step of providing the machine for the treatment of sleep apnea comprises providing a continuous positive airway pressure machine. 5. The method of claim 1, wherein the step of providing the power supply system comprises providing a single enclosure that houses the A.C.-to-D.C. converter, the rechargeable battery and the D.C.-to-D.C. converter. 6. The method of claim 5, wherein the method further comprises providing a fan positioned within the single enclosure and powered by the A.C. power input. 7. The method of claim 1, wherein in the step of providing the A.C.-to-D.C. converter, the rechargeable battery and the D.C.-to-D.C. converter, the A.C.-to-D.C. converter is suitable for converting 120 volts A.C. to 12 volts D.C., the rechargeable battery is a 12 volt D.C. battery, and the D.C.-to-D.C. converter is capable of receiving a D.C. voltage from as low as 9.2 volts to as high as 15 volts and providing the fixed level for powering the machine for the treatment of sleep apnea at an output of 12 volts +/-1%. 8. The method of claim 7, wherein the step of activating the audible alarm comprises activating the audible alarm when an output voltage of the rechargeable battery falls below a threshold of 9.8 volts. 9. The method of claim 1, further comprising the step of providing a solar panel operationally coupled with the rechargeable battery to provide power to the rechargeable battery during daylight hours. 10. The method of claim 1, wherein the step of providing the A.C.-to-D.C. converter comprises providing a constant current switch-mode battery charger. 11. The method of claim 1, wherein the step of providing the D.C.-to-D.C. converter comprises providing over voltage and overload protection. 12. A method of operating a machine for the treatment of sleep apnea and especially suited for distinguishing between a short interruption of A.C. power, which does not require alerting a sleeping patient, and a prolonged interruption of A.C. power, which may require alerting a sleeping patient, comprising the steps of: providing an A.C.-to-D.C. converter for converting A.C. input power to D.C.; providing a rechargeable battery operationally coupled with the A.C.-to-D.C. converter; providing a D.C.-to-D.C. converter operationally coupled with the A.C.-to-D.C. converter and the rechargeable battery, wherein the D.C.-to-D.C. converter receives a D.C. voltage within a range having a minimum and a maximum and wherein the range extends over at least two volts and provides an output D.C. voltage at a fixed level; providing a machine for the treatment of sleep apnea, wherein the machine is powered by a D.C. voltage and is operationally coupled with the D.C.-to-D.C. converter, wherein when the A.C.-to-D.C. converter receives A.C. input power the machine is powered through the D.C.-to-D.C. converter by the A.C.-to-D.C. converter and wherein when the A.C.-to-D.C. converter does not receive A.C. input power the machine is powered through the D.C.-to-D.C. converter by the rechargeable battery; and activating an audible alarm sufficient to wake a patient from sleep when an output voltage from the rechargeable battery is approximately at or near the minimum of the range of the D.C.-to-D.C. converter and the A.C.-to-D.C. converter is not receiving A.C. input power but not when the output voltage from the rechargeable battery is substantially above the minimum range of the D.C.-to-D.C. converter and the A.C.-to-D.C. converter is not receiving A.C. input power. 13. The method of claim 12, wherein the step of providing the A.C.-to-D.C. converter comprises accepting an A.C. voltage ranging from 96-267 volts at 47-63 Hz and converting the A.C. voltage to a nominal 12 volts D.C. 14. The method of claim 12, wherein the step of providing the machine for the treatment of sleep apnea comprises providing a continuous positive airway pressure machine. 15. The method of claim 12, further comprising the step of activating a latched visual indicator upon a loss of A.C. power to the A.C.-to-D.C. converter, wherein the latched visual indicator is insufficient to wake a sleeping patient and wherein the latched visual indicator remains active after resumption of A.C. power to the A.C.-to-D.C. converter until a patient manually resets the latched visual indicator. 16. The method of claim 12, further comprising the step of providing a fan operationally coupled with the A.C. input power. 17. The method of claim 12, further comprising the step of providing a fuse operationally coupled between the D.C.-to-D.C. converter and the machine for the treatment of sleep apnea. 18. The method of claim 12, further comprising the step of providing a fuse operationally coupled between the external rechargeable battery and the A.C.-to-D.C. converter. 19. The method of claim 12, further comprising the step of providing a detachable connector between the D.C.-to-D.C. converter and the machine for the treatment of sleep apnea.
