[Dockstar] Shutdown and Wakeup options

[sambul13]

I am trying to power off ALARM on Dockstar, but using halt, shutdown or poweroff commands with any available options does not result in switching its power off. The device remains warm indicating its still powered indefinitely. Is there a way to switch off its power without removing the power plug? I don't want it to die prematurely due to constant unneeded heatup.

And reversing the question, once the device is powered off or halted, is there a way to wake it up without reboot? How about wake-on-lan feature? For example, if the device is in low power mode, but miniDLNA server is still visible in a media player, would be nice to fully wakeup the device by starting browsing its miniDLNA DB on TV screen. Is that possible?

If powering off the device isn't possible, how to power off its select USB port(s) with connected USB drives? I have media drive in USB enclosure hooked to Dockstar, it stops on its own when not accessed for some time, but its USB PCB remains powered until connected to it devices powers off its USB port.

Poweroff: known issue, being resolved, iirc.

Wake-On-Lan : not supported by the hardware.

Usb: hdparm.

I don't think hdparm will do what I described. My USB drive is already smart enough to stop spinning when the data is not requested for some time. But the enclosure USB PCB remains powered on until the Dockstar USB port power is switched off. There should be a way to switch selected Dockstar USB to a power saving mode or port off, and restore full power to it once the data is requested from the USB drive (by miniDLNA or such). May be some features of PM-Utils and Laptop Mode Tools can provide needed controls? The tools seem to partially overlap functionality and also complement each other.

Ah, I see where you are looking to got with USB power. While I am not immediately aware of the capabilities of that on the dockstar, on ARM it's a bit more complicated than you seem to be accustomed to. If it is the case, it will most likely be available via a GPIO pin, and there just might be something in pm-utils that knows how to make use of that GPIO to disable the power, but I see it as a bit unlikely.

Let me put it this way:
You can put a wake on lan capable network card in an x86 box, but of the motherboard does not support it, you're SOL.



You're SOL.

But is it possible to put the Mobo into one of less demanding power saving states without switching off completely and still retaining lan service, so that it can be fully powered up again once minidlna or similar service is requested by a user say via TV or website (with switching relevant Dockstar USB ports power OFF/ON in the process)?

I got it, WOL isn't there, but leaving LAN port power On and putting the system into a select state may do the trick, as it doesn't seem to require actual wake up from Standby? There are several ACPI states available in Linux Power Management, and hopefully some don't require WOL functionality. The goal is not to heat up Dockstar when not in use. Btw, acpidump utility is available with pmtools to check plug computer board available ACPI tables.

What should at least be possible is to switch the Dockstar power Off completely via xterm shutdown command. Anyone actually checked, why it remains so hot after halting the proc? Something keeps working hard after that resulting in heat buildup, since the power supplied by its adapter is hardly further converted.

Ok:
- search the forum/github issues yourself.
- Mr. SP, then pull the tools and figure it out.

I'm not fluent in Linux enough to resolve such issues on the spot. It requires more experience.
