Partial Ping and Fuel Starvation

I noticed there was a dispute a few days ago about the "partial ping" and fuel starvation and I agree with Porterhouse that this is unlikely. The reason is that even assuming there was enough residual power from the ram turbine or some other source to power the SATCOM the fact is that the firmware of the terminal has to go through a boot sequence when it is powered on again--the length of time which is unknown. The boot sequence could be as little as a few seconds or as long as a minute or two. As an illustration: when the power flickers on and off in one's home the refrigerator powers off and then immediately powers back on again. On the other hand, when the power flickers on and off one's computer simply turns off an does turn on again until one presses the power button and goes through the entire boot sequence.

So it would be a hell of a coincidence for the power to go off from fuel starvation, come back on as the result of the ram turbine or something else, the boot sequence in the SATCOM firmware to comeplete, and just at the precise millisecond it is sending a ping to log-on to the system again the power dies again.
