Experiments on power consumption (iPOD 5G, 30G)

Buschel:
@Llorean: Nevertheless turning off LCD (at least configurable for own build) could be a good point for additional power savings.

@linuxstb: Yes, putting the disk in sleep mode is what I understood from the source. Do you know how to completely power down the disk?

If I (or anyone else) knew how to do that, it would be in the code in a heartbeat.

AFAIK, no-one has done any serious investigation (i.e. disassembling the original firmware and/or experimenting with the aid of a multimeter to investigate how different hardware settings affect power consumption) of the ipod hardware - which is what's required.

mnhnhyouh:
Just a quick side note, and possibly a helpful hint, the power drain on the iRiver H320 was discovered, IIRC, by a thermal camera. This showed extra power consumption by the USBOTG chip.

Worth a try for the iPod?

Llorean:
Not likely to be. This has been suggested a few times, but the general feeling is that it's the PortalPlayer chip that's the problem, since the problem persists on all PP targets. Using an IR thermometer would just tell us what we already suspect: It's the PP chip and we don't know enough about it to know how to resolve it.

robin0800:
Just wonder if using electronic test equipment Logic Analyzers Ociliscopes etc the PortalPlayer chip, when running original firmware could give up its secrets, power supplies, data lines, signal input lines and outputs.
Just a thought.
